A gossypiboma (a retained surgical sponge) usually has the characteristic appearance on CT of a soft tissue mass with air-bubbles and a whirl-like pattern. This finding may be confused in the early post-operative period with an abscess, especially when a fistula is present. We describe two patients, in whom this diagnosis was initially missed. A soft tissue mass containing air-bubbles in the early post-operative period with or without a fistula should include a retained pad, in the differential diagnosis. 相似文献

Gossypiboma is a foreign object, such as a mass of cotton matrix or a sponge, that is left behind in a body cavity during surgery. It is uncommon, mostly asymptomatic, and hard to diagnose. It may be incorrectly diagnosed preoperatively, which can lead to unnecessary invasive diagnostic procedures and operations. It should be included in the differential diagnosis of soft-tissue masses detected in patients with a history of a prior operation. We present a case of 36-year-old female who referred to emergency room with severe abdominal pain and distension. Imaging revealed a giant intra-abdominal mass resembling a soft tissue tumor, but revealed to be a giant gossypiboma caused by a sponge that was forgotten during previous ectopic pregnancy surgery. This case differs from others with the absence of findings supporting gossypiboma such as calcification or trapped gas bubbles and emphasizes the importance of this potentially life-threatening complication of surgery. 相似文献

An intrathoracic gossypiboma is a rare condition. Moreover, intrathoracic gossypibomas with intrapulmonary location are extremely rare and only a few cases of intrapulmonary gossypiboma have been published. Usually gossypiboma has the characteristic CT appearance of a soft tissue mass with high attenuation, air bubbles and a whirl-like pattern, but its radiological manifestations may be variable according to the location and chronicity of the sponge. We report a case of intrathoracic gossypiboma initially misdiagnosed as an aspergilloma owing to its intrapulmonary location and air crescent sign on CT. In addition, our case will show morphological changes of the gossypiboma on CT during the 10 year follow-up period and correlate the CT findings with pathological results. 相似文献

FDG PET CT features of an intraabdominal gossypiboma 总被引:1,自引:0,他引:1
Retained surgical sponge or gossypiboma in the abdominal cavity is an infrequent but serious surgical complication that may lead to medicolegal problem. The incidence of a surgical sponge retained at operation is difficult to estimate, but it has been reported as 1 in 100 to 3000 for all surgical interventions and 1 in 1000 to 1500 for intraabdominal operations. The natural evolution of a retained sponge, if aseptic, is to cause a foreign body reaction, followed by organization to form a foreign body granuloma, which may mimic a soft tissue neoplasm. Although features of CT and MR imaging of gossypibomas have been documented in the literature, they have often been misinterpreted preoperatively owing to the rarity of gossypibomas in daily clinical practice and to the low index of clinical suspicion. We report the FDG PET CT findings of a 42-year-old woman who had undergone cesarean sections twice previously, with an intraabdominal gossypiboma found incidentally in a routine health examination. We hope the PET CT findings in this case offer us useful adjunctive information to conventional imaging studies in the diagnosis of gossypiboma. 相似文献

Retained surgical gauzes: acute and chronic CT and US findings 总被引:2,自引:0,他引:2

Surgical sponges retained after laparotomy represent a diagnostic problem if they cannot be identified by radiopaque markers on standard radiographs. We report on 9 patients from different hospitals with an abdominal gossypiboma 7 days to 21 years after the surgical procedure. Plain radiographs may suggest the diagnosis if a textile foreign body is calcified, that is, is equipped with radiopaque marker, or when a characteristic "whirl-like" pattern is present. CT and US are necessary procedures in chronic cases, since the lesion may mimic a mass; US shows specific echogenic areas with acoustic shadow; CT usually reveals a hypodense mass with a thick peripheral rim. 相似文献

A 51-year-old Korean woman with a history of breast cancer underwent screening bone scintigraphy, which revealed minimal soft tissue uptake of Tc-99m methylene diphosphonate (MDP) in the right lower quadrant. CT and plain films confirmed that the uptake was due to a retained surgical sponge or gossypiboma. The incidence of gossypibomas has been reported at high as 1 in 1000 to 15,000 intra-abdominal operations. The natural progression of an aseptic gossypiboma is a foreign body reaction and granuloma formation. This inflammatory granulomatous reaction is the most likely cause of the extraosseous accumulation of Tc-99m MDP. This entity should be added to the already extensive list of etiologies of extraosseous MDP accumulation. 相似文献

The patient was a 61-year-old man who developed gossypiboma of the left thigh and femur resulting in the imaging appearances of a malignant surface tumor. He had a past history of surgery on the left femur for open fracture 40 years previously. Radiographs and CT showed a soft tissue mass with osteolysis and periosteal thickening of the left femur. On MRI, the mass showed heterogeneous signal intensity with contrast enhancement at the periphery, suggesting a malignancy. 99mTc-HMDP bone scintigraphy showed a faint ring-like uptake, but thallium -201 scintigraphy did not show any uptake in the tumor. An extensive intralesional excision was performed. Postoperative histopathological examination showed a fibrous foreign body with reactive changes. There were neither viable cells nor atypical giant cells around the foreign body. No malignant change was evident. Based on surgical and histopathological examinations, the tumor was finally diagnosed as gossypiboma related to a retained surgical sponge.The patient was treated by Dr. Kenshi Sakayama at Ehime University Hospital, Ehime, Japan 相似文献

The CT appearance of ectopic bone and its maturation in 25 patients were correlated with the findings on radiographs and bone scans. Ossification progressed from an early appearance of soft-tissue density of lower attenuation than muscle to a calcific density paralleling radiographic and scintigraphic evidence of bone formation. Persistent unossified, low-density soft tissue was detected adjacent to mineralized areas of ectopic bone in 14 patients up to 16 years after neurologic injury, often with bone-scan evidence of maturity of the ectopic bone. This soft tissue most likely corresponds to immature, unossified connective tissue, which may have a potential for ossification. Detection of areas of soft-tissue density by CT and their avoidance during surgical resection of an ankylosing mass of ectopic bone may reduce intraoperative hemorrhage and postoperative ectopic bone recurrence. 相似文献

PURPOSE: This study was undertaken to determine the feasibility of perioperative high-dose-rate brachytherapy (PHDRB) as an accelerated boost in patients with pediatric sarcomas. METHODS AND MATERIALS: Five pediatric patients (ages 7-16) with soft tissue sarcomas (STS) or soft tissue recurrences of previously treated osteosarcomas were treated with surgical resection and PHDRB (16-24 Gy) for R0-R1 resections. Patients with STS and osteosarcomas received 27 Gy and 45 Gy of EBRT postoperatively. RESULTS: After a median follow-up of 27 months (range, 12-50) all the patients remain locally controlled. Only 1 patient developed regrowth of pulmonary metastases and died of distant disease at 16 months. CONCLUSIONS: The use of PHDRB is safe in the short-term in this pediatric population. Only 1 patient suffered a partial wound dehiscence that may not be entirely related to PHDRB. Patients with recurrent osteosarcomas can be treated in a fashion similar to their adult soft tissue counterparts and avoid limb amputation. Younger patients with STS may achieve local control and prevent growth retardation with a combination of PHDRB and moderate doses of EBRT. 相似文献

Approximately 5% of patients with end-stage cirrhosis undergoing orthotopic liver transplantation have occult hepatocellular carcinoma. Careful follow up is required to detect recurrent tumour, and knowledge of the patterns of recurrence may avoid diagnostic confusion with other malignancies, such as post-transplantation lymphoproliferative disorder. This case report illustrates an unusual presentation of recurrent hepatocellular carcinoma in a 56-year-old man presenting with a para-aortic soft tissue mass, thought clinically and radiologically to represent lymphoma or post-transplantation lymphoproliferative disorder. This case demonstrates that recurrent hepatocellular carcinoma can present late after transplantation as retroperitoneal lymphadenopathy, and should alert physicians and radiologists to be aware of the radiological appearances of recurrence and of the need for early biopsy to avoid diagnostic confusion with other malignancies. 相似文献

The retention of foreign bodies after surgery is rare, but carries significant morbidity and mortality as well as financial and legal implications. Such retained items cause a foreign-body reaction, which in the case of cotton-based materials are called gossypibomas. We present the case of an 84-year-old woman with a pseudotumor secondary to a retained dressing gauze roll, presenting 5 months after resection of a gluteal sarcoma, which had raised concerns of local recurrence. We also outline the imaging modalities that may assist in diagnosis of a retained foreign body, and suggest the MRI “row of dots” sign as a useful radiological feature associated with gossypiboma. Awareness of the imaging appearances of retained foreign bodies allows the inclusion of this possibility in differential diagnosis of a mass in patients with a surgical history. 相似文献

Can FDG PET be used to successfully direct preoperative biopsy of soft tissue tumours? 总被引:4,自引:0,他引:4

Magnetic resonance imaging (MRI) has been the most useful tool in the anatomical definition of soft tissue sarcoma, although there remains the problem of defining the lesions as benign or malignant. The management of such lesions requires biopsy prior to surgical resection. If the most malignant area could be defined more accurately, then this area could be targeted for biopsy. Fluorodeoxyglucose positron emission tomography (FDG PET) has been found to be useful in identifying malignancy and variations in grade in soft tissue masses. The aim of this study was to assess the use of FDG PET scanning with or without co-registered MRI to indicate the most appropriate biopsy site. Twenty consecutive patients presented with soft tissue masses with clinical signs of malignancy. All patients underwent MRI and FDG PET scanning and the two images were co-registered. A biopsy site that was the most likely to be malignant was defined on the PET scan. All patients underwent an initial biopsy and then complete surgical resection of the mass. The histological results from the mass were compared with those from the biopsy specimen obtained from the site suggested by the PET scan. In malignant masses the biopsy site suggested by the FDG PET scan was found to be representative of the most malignant site on the whole mass histology. Benign lesions had low or no FDG uptake. In no case did the co-registered image add significantly to the appropriate biopsy site. FDG PET can be used to appropriately direct biopsy in soft tissue sarcoma and potentially may lead to computed tomography/MRI directed outpatient biopsy prior to definitive treatment. 相似文献

It should be clear to those who perform and interpret medical images of the spine following one or more forms of surgical therapy that the images are often difficult to interpret in part because of the superimposition of the original disease process, alteration engendered by the surgery, or a complication of the surgical procedure. Although long-term experience in this area is helpful in regard to improving interpretive skills, certain sequela can be predicted regardless of the interpreter's background. Once the normal or expected postsurgical findings are understood, the subtle and gross changes that depart from these observations can be analyzed better. The importance of a high level of competence in the domain of post-therapeutic neurodiagnostic imaging is in the knowledge that the patient returning for restudy may be acutely in distress or even in medical danger (e.g., postoperative spondylitis). In fact, the clinical presentation posttherapeutically may well be more severe or dire than was observed pretherapeutically. An indepth appreciation of the broad range of clinicoradiologic possibilities as presented [figure: see text] here should place the medical imaging physician in an excellent position to provide an experienced diagnostic evaluation in the patient presenting with recurrent or new signs and symptoms following any one of the spectrum of possible spinal surgical procedures. 相似文献

Intrathoracic gossypiboma, a retained surgical sponge in the thoracic cavity, is a rare but serious consequence following surgery. Because of its rare occurrence and non-specific clinical and radiographic presentations, the diagnosis is often missed. Herein we report a patient presenting with a chronic recurrent cough due to a retained surgical sponge in the pleural cavity. The patient has been misdiagnosed with bronchiectasis for 22 years. The characteristic spongiform appearance on CT and a history of previous thoracic surgery led to the diagnosis of a gossypiboma that was confirmed at surgery. 相似文献

Fibroma of the tendon sheath, a rare benign soft tissue tumor that most often occurs in the distal upper extremities (hands and wrist), is exceedingly rare to present as an intraarticular mass. Presented here is the first case in the English literature, to our knowledge, of a fibroma of the tendon sheath arising in the acromioclavicular joint. The patient presented with recurrent shoulder pain with activity without antecedent trauma. Radiographs were essentially normal. MR images demonstrated a lobulated, heterogeneous mass with contrast enhancement arising from the acromioclavicular joint. Following surgical resection, histopathology revealed hypocellular collagen matrix with spindle-shaped fibroblasts, confirming the diagnosis of fibroma of tendon sheath. The imaging features of the fibroma of the tendon sheath and a brief review of the literature are presented. 相似文献

This study reviews the clinicoradiological features of cranial and sacrospinal chordomas and identifies factors affecting survival. Nineteen patients seen between January 1980 and December 2000 with histopathological diagnosis of chordomas were retrospectively reviewed with reference to clinical presentation, imaging features, treatment modalities and post-therapy status. Eight had tumours in the skull base while 11 patients had spinal and sacrococcygeal lesions. Surgical resection was performed in 16 patients whose subsequent natural history was used to identify clinical indicators that may influence survival. Completeness of resection, age, gender and postoperative irradiation were subjected to analysis using the Cox proportional hazard models. Kaplan-Meir survival curves illustrate the survival distributions. Diplopia and facial pain are prime clinical presentations in cranial lesions, while extremity weakness and a sacrogluteal mass are common complaints in the sacrospinal group. Lesional calcifications are present in 40% while an osteolytic soft tissue mass is detectable by CT in all cases. Heterogeneous signals and internal septations on T2-weighted MRI are predominant features. In sacrospinal tumours, complete excision with adjuvant radiotherapy achieves the best results with a disease-free survival of more than 5 years. The clinical and imaging findings in this study are in accordance with those of other series. Except for complete surgical excision followed by radiotherapy in the subset of patients with sacrospinal tumours, none of the other clinical indicators show a statistical significant influence on survival. 相似文献

We report a 22-year-old man with a solid mass in the right proximal leg, which was furned out to be a gossypiboma. MR imaging revealed a well-defined mass lesion that showed intermediate signal intensity at T1-weighted imaging (T1WI) and slightly high signal intensity at T2-weighted imaging (T2WI). Wavy, low-signal-intensity stripes were visible within the fluid-filled central cavity. At surgical exploration, a sponge, retained after previous knee surgery, was discovered, and it was found that a granuloma had developed. Pathologic examination revealed granulomatous inflammation, with lymphocyte and giant cell infiltration. The presence of wavy, low-signal-intensity gauze fibers at T2WI may be a characteristic MR appearance of gossypiboma. 相似文献

Although newer imaging techniques aid in the diagnosis of soft tissue sarcomas and current surgical procedures and adjunct therapy decrease the incidence of their recurrences when patients are referred to oncologic centers, the majority of these tumors are suboptimally evaluated in general practice with frequent recurrences. Close surveillance of these patients is necessary for early recognition and treatment of recurrent disease. This article describes an organized, stepwise magnetic resonance imaging evaluation of these patients after surgery and radiation therapy. The initial sequence should be T2-weighted. Low signal intensity or diffuse high signal intensity without mass on T2-weighted sequence excludes recurrence in 99% of patients. A high signal intensity mass, however, should be studied with bolus injection of contrast medium. Although standard contrast-enhanced MR imaging differentiates the non-enhancing hygroma or hematoma from the enhancing recurrence or pseudotumor, dynamic contrast-enhanced MR imaging is required to distinguish the rapidly enhancing recurrent tumor from the slowly enhancing pseudotumor of inflammation. 相似文献
