Nonsurgical management of thyroid abscess with sonographically guided fine needle aspiration

Treatment of thyroid abscess commonly includes the surgical drainage along with systemic antibiotic therapy. Alternatives for open surgical intervention may be the conservative management with use needle aspiration or catheter drainage. We report here two cases of thyroid abscess treatment with 21-gauge needle aspiration under ultrasound guidance. In each case needle drainage was performed twice, at the 1st and 5th day of admission. Antibiotics were administered in pills and injected into the abscess cavity followed the pus aspiration and lavage. Both patients were cured. Follow-up has not revealed recurrence during 6 month and 5 years.

Treatment of prostatic abscess: value of transrectal ultrasonographically guided needle aspiration.

The purpose of this study was to assess the effectiveness of transrectal ultrasonographically guided needle aspiration in the treatment of prostatic abscess. Fourteen patients with prostatic abscess were evaluated with this technique and treated with sonographically guided needle aspiration. Using this technique, all cases (100%) had one or more hypoechoic areas within the prostate that contained inhomogeneous materials; in 10 patients (71.0%), the lesion showed internal septa or solid portion. The margins of the hypoechoic area were well defined and thick in 11 patients (79.0%) and poorly defined in 3 patients (21.0%). The estimated volume of the prostatic abscess ranged between 2 and 28 ml (mean, 12.0 ml). The presence of a pus collection within the prostate was confirmed by transrectal ultrasonographically guided aspiration in all patients. However, successful treatment of prostatic abscess with transrectal needle aspiration was done in 12 (86.0%) of 14 patients; the treatment failed in 2 (14.0%) of 14 patients. One patient was treated with perineal incision and drainage and the other with transurethral resection. The amount of pus drained ranged between 1 and 39 ml (mean, 12.0 ml). On follow-up transrectal ultrasonographic examination, no remaining abscess pocket was found within the prostate in any of the cases. One year later, the prostatic abscess recurred in one case. In conclusion, transrectal ultrasonographic guidance is useful in the diagnosis of prostatic abscess as well as in the guidance for aspiration and the drainage of such abscesses. Transrectal ultrasonographically guided needle aspiration could be an effective method for treating prostatic abscess.     

A novel approach to enhance visualization during drainage of peritonsillar abscess

Routine emergency department care for uncomplicated peritonsillar abscess involves needle aspiration or incision and drainage. Standard technique involves use of a tongue blade and auxiliary light source. We describe the novel use of a disassembled disposable vaginal speculum with fiberoptic light, a device becoming commonplace in many emergency departments. This novel approach to managing peritonsillar abscess greatly enhances visualization and facilitates peritonsillar abscess drainage.     

Aspiration and injection-based technique for incision and drainage of a sacrococcygeal pilonidal abscess

The incision and drainage of a sacrococcygeal abscess is a common procedure in the Emergency Department (ED) both to decrease a patient's pain and to improve the local wound conditions for subsequent definitive surgical therapy. However, the local infiltration of anesthetics is often problematic due to the unacceptable and unavoidable pain resulting from the injection itself, as well as the inability to achieve a complete anesthetic response. Therefore, standard textbooks generally recommend the concomitant use of local and systemic analgesics in the treatment of sacrococcygeal abscesses. We describe herein an alternative technique to administer local analgesia after the aspiration of an abscess for incision and drainage of a sacrococcygeal abscess that is safe and rapid. The patient is placed in the prone position and the buttocks are separated from the midline with adhesive tape. The technique involves needle aspiration of the abscess with consecutive slow injections of the same amount of local anesthetic into the abscess cavity via the same needle, followed by abscess drainage by incision and gentle curettage. This method therefore eliminates multiple infiltrations of the abscess and the surrounding area and obviates the associated pain due to the low volume of anesthetic required. The described technique is well tolerated by the patient and reduces the frequently encountered difficulty with incision and drainage of coccygeal abscesses in the ED.     

Percutaneous management of breast abscesses. An experience of 39 cases

This is a review of our experience with percutaneous drainage by means of needle aspiration or catheter drainage of breast abscesses under ultrasound (US) guidance, and a suggested management algorithm. A retrospective study of the 39 patients (36 women, 3 men; mean age: 28.9 years) with breast abscesses who were treated by percutaneous US-guided procedures over a period of 13 years (1989 to 2002) was carried out. Of the 36 women, 34 were nonlactating and two lactating. Needle aspiration was used in the cases of fluid collections < or = 3 cm and catheter drainage in fluid collections of > 3 cm. Postdrainage care and US evolutive controls were carried out on an outpatient basis. Fine-needle aspiration cytology was performed in masses unresolved after postdrainage. Mammography was performed in patients over 30 years old. In all cases, US examination revealed images of fluid collection. A single needle aspiration was sufficient in 19 cases; 3 patients needed a second aspiration to resolve the breast abscess. A total of 15 cases were resolved by means of percutaneous catheter drainage. In 2 of the 17 patients who underwent catheter drainage, the mass persisted postdrainage; histologic findings showed a chronic abscess requiring surgical intervention in one and a breast carcinoma in the second. Mean follow-up was 8.4 months. Recurrence of breast abscess occurred in 4 patients, and these were resolved by surgical excision. Percutaneous drainage procedures in breast abscesses are a safe and effective alternative to incision and drainage. Needle aspiration is employed in cases of small abscesses and catheter drainage in abscesses larger than 3 cm. Although, in chronic abscesses, the treatment of choice is surgical excision, percutaneous drainage remains as an intermediate therapeutic option.     

Peritonsillar abscess. Why aggressive management is appropriate

Peritonsillar abscess is the most common deep neck infection in adults. Infections develop from purulent material collecting in the fascial spaces lateral to the capsule of the palatine tonsil. Infections are usually polymicrobial, and a significant number of anaerobes are isolated. The cornerstone of therapy is drainage of the abscess. With cooperative patients, careful permucosal needle aspiration is an accepted method of primary therapy. Large or recurrent abscesses require otolaryngologic consultation for adequate incision and drainage. Tonsillectomy may be necessary to prevent re-formation of abscess in patients with a history of recurrent tonsillitis.     

Ultrasound-guided drainage of peritonsillar abscess by the emergency physician

The diagnosis of peritonsillar abscess (PTA) poses a challenge to emergency physicians (EPs). The decision to perform an invasive procedure with potential complications is based on clinical judgment that is often inaccurate. Although there is some mention of intraoral ultrasound in otolaryngology practice, there is none in the emergency medicine (EM) literature. However, this bedside emergency application of ultrasonography has the potential to be of considerable use in EM practice, and could allow EPs who previously deferred blind needle aspiration of a potential abscess to perform the procedure themselves. We report the cases of 6 patients who presented with probable PTA and were evaluated with intraoral ultrasound at the bedside by an EP. All 6 patients then underwent needle aspiration. As diagnosed on ultrasound, 3 of the patients had negative aspirations and were diagnosed with peritonsillar cellulitis. Three others were found to have PTA, with 2 requiring real-time ultrasound needle guidance to accomplish abscess drainage after multiple failures with the blind approach.     

Tuberculous abscess of the thyroid gland: a report of two cases

Tuberculosis of the thyroid gland is very rare, with an acute abscess formation being the least common form of presentation. We report the sono-graphic features of two cases of tuberculous thyroid abscess that were confirmed via ultrasound-guided fine needle aspiration biopsy.     

Supralevator abscess: Evaluation with transrectal sonography

Transrectal ultrasound was used in 2 patients with supralevator perirectal fluid collections. In one instance, this technique was used to diagnose and plan surgical drainage of a perirectal abscess. In another patient needle aspiration under sonographic guidance was performed for removal of a septated fluid collection.     

TUBERCULOUS MASTITIS: A RARE DISEASE

SUMMARY Two cases of tuberculous mastitis are described. This disease remains rare. While routine laboratory investigations are not helpful in its diagnosis, fine needle aspiration to allow histologic examination of tissue and culture is essential — both to differentiate tuberculous mastitis from pyogenic breast abscess and breast carcinoma, and to guide antimicrobial therapy. Antituberculous drugs in combination with aspiration or surgical drainage are usually associated with an excellent outcome.     

Ultrasonically guided percutaneous drainage of abdominal fluid collections: A long-term study of its therapeutic efficacy

Fifty patients underwent ultrasonically guided percutaneous drainage (US-GPD) either with needle aspiration or catheter drainage. The procedures resulted in 70% complete recovery, 20% partial success and 10% of failures. The same patients were followed with clinical examination and sonography for a mean time of 36.3 months (minimum follow-up: 12 months). During the follow up period, 10 relapses occurred and one patient, considered for surgery after partial percutaneous treatment of a pyogenic liver abscess, recovered completely under conservative treatment. An analysis of the factors potentially related to the recurrence was made. It was found that one-step needle aspiration of abdominal abscesses and percutaneous treatment of chronic pancreatic pseudocysts are more prone to relapses. We conclude that US-GPD is an efficacious therapy for abdominal fluid collections, but an adequate drainage technique and a careful selection of the patients is crucial to avoid the possibility of relapse.     

Value of ultrasonography, fine needle aspiration, and percutaneous drainage of perinephric abscesses

With the advent of ultrasonography, perinephric fluid collection can be easily diagnosed and confirmed by fine needle aspiration. In the past these cases sometimes went undiagnosed for several months. We did fine needle aspiration under the guidance of ultrasonography in 16 patients without complications. The aspirant in 12 patients was purulent, confirming the diagnosis of perinephric abscess. In the remaining four the aspirated fluid was nonpurulent and the diagnosis was urinoma or hematoma. Percutaneous drainage was established in five of the 12 patients. The technique is safe and easy to perform, and may be the only treatment necessary in selected cases, thus avoiding unnecessary surgery and prolonged hospitalization.     

Prostatic abscess: transrectal color Doppler ultrasonic diagnosis and minimally invasive therapeutic management

The purpose of this study was to analyze the transrectal ultrasound (US), or TRUS, and color Doppler ultrasonography (CDU) findings and therapeutic strategies with TRUS-guided procedures in 13 patients with prostatic abscess. Over a period of 6 years, 18 prostatic abscesses were diagnosed in 13 patients (mean age: 59 years). Diagnostic workup included TRUS, analysis of midstream urine, and analysis and culture of abscess fluid for leukocytes and pathogens. These patients were treated either conservatively (for abscess cavities < 1 cm in diameter), or by aspiration or draining procedures (cavities > or = 1 cm). The transrectal CDU findings were correlated to the treatment effects. The predisposing factors were also reviewed. In the 13 patients, the most common clinical symptom and sign were urinary frequency (77%) and pus cell in the midstream urine (92%). Predisposing factors were found in 11 men, with diabetes in 5 of them. In 10 patients, the definitive preinterventional diagnosis was based on the TRUS findings. TRUS with probe palpation demonstrated tiny floating echogenic speckles in the abscess cavity in 4 patients. CDU demonstrated increased color-flow signals at the margin and surrounding tissue of the abscess pockets. Abscesses with poorly defined boundaries had more prominent surrounding color-flow signals and achieved, with relative difficulty, a satisfactory aspiration procedure. Aspiration was done for all 11 abscesses between 1 and 3 cm. A total of 4 larger abscesses (> 3.0 cm) were treated with aspiration or drainage using a 5-French pigtail catheter. No surgical drainage was performed. Transrectal CDU may help in the evaluation of maturity of an abscess pocket. US-guided aspiration with an 18-gauge needle or drainage with a 5-French pigtail catheter significantly shortened the hospital stay.     

Pyomyositis

Pyomyositis is a bacterial infection of skeletal muscle that is usually accompanied by abscess formation. Staphylococcus aureus is the most common causative organism. Pyomyositis should be suspected in any patient who presents with fever, muscle pain and leukocytosis. It is confirmed by needle aspiration and culture of the suspected muscle group. Treatment entails incision and drainage of abscesses and appropriate antibiotic therapy.

The sacral hiatus approach for drainage of anterior lumbo-sacral epidural abscesses. A case report and technical note

Lumbosacral epidural abscesses are managed either conservatively with IV antibiotics or with open surgery, particularly in the presence of acute neurological symptoms. Their location makes it difficult for image-guided interventional approaches either for biopsy or evacuation. We report the sacral hiatus and canal as a corridor for image-guided minimally invasive abscess of lumbosacral epidural abscess for aspiration. A 56-year-old man presented to the emergency department complaining of six weeks of worsening low back pain. MRI of the patient's lumbosacral spine showed osteomyelitis involving his L5, S1 vertebrae, L5-S1 discitis, as well as an anterior epidural abscess extending from L4-5 disc space to the S2 vertebral level. Blood cultures grew out gram-positive cocci. For drainage, a 5-French micropuncture kit was utilized to access the hiatus. Under fluoroscopic guidance a microwire was then advanced along the sacral canal. An 18-gauge needle curved to approximate the contours of the sacral canal was then advanced over the guidewire. Once anatomic access was established 2 ml of thick purulent material was aspirated. The patient tolerated the procedure well, and no focal nerve root symptoms were noted following the procedure. Image-guided aspiration of lumbosacral epidural abscesses can thus be carried out in a safe and effective manner using a sacral hiatus approach.
