Objective Arachnoid cysts constitute 1% of all intracranial mass lesions not resulting from trauma. Suprasellar arachnoid cysts (SACs)
are uncommon. Obstructive hydrocephalus is the most common cause of initial symptoms and occurs in almost 90% of the patients
with suprasellar arachnoid cyst. We report on 17 patients with suprasellar arachnoid cyst who were treated with neuroendoscopic
intervention.
Materials and methods Seventeen patients with SAC had been operated on between 1999 and 2007 in our institution. Five patients had previously undergone
shunting procedures or craniotomy. Nine boys and eight girls ranged in age from 4 months to 17 years (mean 53.2 months). All
patients had hydrocephalus. A wide ventriculocystostomy (VC) or a ventriculo-cysto-cisternostomy (VCC) was done by using rigid
neuroendoscopes. Psychometric evaluation was administered postoperatively, when possible. Follow-up of the patients ranged
from 6 months to 7 years (mean 41.6 months).
Results Of the 17 patients, 12 underwent endoscopic procedure as the primary surgery. VC only was performed in the first patient.
In the remaining 16 patients, VCC was done. A slit-valve mechanism was observed in 14 patients. Three patients needed a VP
shunt, despite a successful VCC. Three of five patients, younger than 1 year of age became shunt dependent and none of the
patients older than 1 year of age needed shunting. In four patients presented with shunt malfunction, the shunts were removed
after endoscopic surgery. Only one subject’s total score was under the normal IQ limits but her subtests scores were heterogeneous.
However, there was marked discrepancy among her subtests scores.
Conclusion Endoscopic surgery should be the first choice in the management of SACs. Neuroendoscopic VCC is successful in the majority
of the cases.

Purpose
The purpose of the study was to investigate the predictive value of stone measurements by including a novel method on non-contrast computed tomography (NCCT) images for stone composition.Methods
We retrospectively evaluated patients who had stone analysis, NCCT images, and underwent percutaneous nephrolithotomy between 2013 and 2016. Patient characteristics, stone measurements on NCCT images, and stone analysis results were evaluated. Hounsfield unit (HU) values (maximum (HUmax), minimum (HUmin), and average (HUave) of HU values) were investigated on NCCT images. HUdiff was calculated as the difference between the HUmax and the HUmin values. Patients were divided into seven stone groups and data were compared. Then patients were separately divided into two groups according to mineral complexity (mono-mineral and multi-mineral groups) and calcium-based (calcium and other stone groups) evaluation.Results
In the study, 115 patients were evaluated. Age, gender, HUmin, HUmax, and HUave were significantly different between the stone groups. HUdiff and HUave were found to be 341.5 HU (AUC?=?0.719, p?=?0.017) and 1051.5 HU (AUC?=?0.701, p?=?0.029) as cut-off, respectively. Seventy of 72?>?341.5 HUdiff patients and 64 of 67?>?1051.5 HUave patients had multi-mineral stones (p?=?0.001, OR 9.26, and p?=?0.028, OR 4.27), respectively. In multivariate analysis, >?341.5 HUdiff rate was significantly higher in multi-mineral and calcium stone groups; HUave was also significantly higher in the calcium stone group.Conclusions
HUdiff and HUave were significant predictors of mineral complexity. HUdiff of <?341.5 HU showed 81.8% sensitivity and 67.2% specificity for identification of mono-mineral stones.84.

Purpose
To determine the value of diffusion-weighted magnetic resonance imaging (DW-MRI) in discriminating between hepatic alveolar echinococcosis (AE) and hepatocellular carcinoma and intrahepatic cholangiocarcinoma.Methods
We included 49 patients (27 men, 22 women; mean age: 52.02 ± 9.76 [SD] years; range: 25–72 years) with 57 histopathologically confirmed hepatic AE lesions. Fifty patients (18 men, 32 women; mean age: 58.93 ± 8.42 [SD] years; range: 42–71 years) with 61 histopathologically confirmed hepatocellular carcinoma and 50 patients (24 men, 26 women; mean age: 50.11 ± 7.70 [SD] years; range: 38–69 years) with 54 histopathologically confirmed intrahepatic cholangiocarcinoma lesions were used as control groups. All patients had MRI examination of the liver that included conventional MRI sequences and DW-MRI using b values of 50, 400 and 800 s/mm2. Two radiologists evaluated conventional MRI and DW-MRI images and calculated ADC values of hepatic lesions.Results
The mean ADC value of solid components of hepatic AE lesions was 1.34 ± 0.41 × 10?3 mm2/s (range: 0.9–1.59 × 10?3 mm2/s) and was significantly higher than that of the solid components of hepatocellular carcinoma lesions (mean ADC value, 0.99 ± 0.29 × 10?3 mm2/s; range: 0.7–1.15 × 10?3 mm2/s) and of intrahepatic cholangiocarcinoma lesions (mean ADC value, 1.05 ± 0.22 × 10?3 mm2/s; range: 0.86–1.18 × 10?3 mm2/s) (P < 0.001).Conclusion
In general ADC values can help discriminate between AE and hepatocellular carcinoma and intrahepatic cholangiocarcinoma. However, the use of ADC values cannot help differentiating Type 4 AE from hepatocellular carcinoma or intrahepatic cholangiocarcinoma. 相似文献85.

Objective: The aim of this study was to assess the efficacy of suction-assisted liposuction (SAL) in Simon grade 2b gynecomastia and its effect on sternal notch to nipple areola (SNN) distance.Methods: A retrospective analysis was performed on 21 patients with grade 2b gynecomastia who underwent SAL. Preoperative and postoperative SNN distances of the patients were measured, the results were analysed using a Mann–Whitney U test and a p-value <.05 was accepted as statistically significant. Aesthetic results were evaluated by the surgical team considering five criteria: breast size, breast shape, nipple-areolar complex positioning, scarring, and skin tightness of the breast envelope. A 10-point Likert scale was used to assess patient satisfaction with SAL surgery.Results: All of the patients were followed up for an average period of 17.8 months (range?=?12–28 months). The mean amount of lipoaspirate was 232?mL per breast (range?=?190–310?mL). The mean preoperative SNN distance was 22.3?cm (range?=?20–23.5?cm), whereas postoperative was 21.3?cm (range?=?19.2–22.8?cm); the difference was statistically significant (p?.05). There was one case of nipple areola necrosis, three hypoesthesia, five persistent pains, and four slight buttonhole deformities. The aesthetic result was evaluated as very good by the surgical team, and the overall patient satisfaction rate in terms of breast shape and volume was 92%.Conclusions: It was concluded that SAL provides a good aesthetic outcome in patients with Simon grade 2b gynecomastia and shortens the SNN distance by 1?cm, but further clinical studies are required to support this conclusion. 相似文献

Physicians are often confronted with the problem of differentiating between depression and anxiety. In accumulated data on 500 patients with subsequent diagnosis and successful treatment of primary depression, only a few had had a tentative diagnosis of depression rather than anxiety. Failure to differentiate between depression and anxiety results in inappropriate and ineffective treatment. 相似文献

Diseases and tumors of the appendix vermiformis are very rare, except for acute appendicitis. This study aimed to examine rare findings in the histopathologic examinations of specimens of patients undergoing appendectomy due to the diagnosis of acute appendicitis. The files of 1970 patients undergoing appendectomy due to the diagnosis of acute appendicitis between March 2012 and March 2016 were retrospectively investigated. Rare findings were found in 59 (3 %) patients, and these were evaluated in detail. Patients’ age, gender, pathology reports, and postoperation follow-ups were recorded. The rare histopathological findings of 59 patients were examined. Of these, 31 were female (52.5 %) and 28 were male (47.5 %). The average age was 33.1 ± 18.2 years. The unusual findings were as follows: 16 fibrous obliteration, 11 Enterobius vermicularis, 2 schistosomiasis, 3 appendiceal neuroma, 2 granulomatous appendicitis, 1 Crohn’s disease, 3 chronic appendicitis, 1 endometriosis, 2 hyperplastic polyps, 9 mucinous cystadenoma (+mucocele), 8 carcinoid tumors, and 1 lymphoma. All of the malignant tumors were localized in the distal end of the appendix, and all of the patients were treated with appendectomy. Patients with parasitic diseases also underwent anthelmintic treatment, while chemotherapy was administered to the patient with lymphoma. All of the patients diagnosed with malignancy were alive reported no problems at their follow-ups. Although all of the appendectomy samples were normal macroscopically, data from this study suggest that all specimens should be sent for routine investigation. 相似文献

Colitis cystica profunda (CCP) is an uncommon benign condition characterized by mucin-filled cysts located in the submucosa,
frequently associated with the solitary ulcer and rectal prolapse syndromes. The diagnosis of this entity is important as
it can mimic rectal cancer and therefore may result in unnecessary surgical resection. Endoscopic examination and barium enema
findings are suggestive but not specific, neither are superficial biopsy findings. Transrectal ultrasound is helpful in the
diagnosis by imaging the layers of the rectal wall. The authors report a 16-year-old male with a rectal lesion mimicking malignant
mass on endoscopic examination. The lesion was defined as CCP, based on MR imaging findings which disclosed multiple noninfiltrating
submucosal cysts, confirmed by histopathological examination. To our knowledge, this is the first case of CCP in the radiology
literature describing MRI findings. 相似文献

Extramedullary plasmacytomas are rare tumors. In majority of cases tumors arise in the head and neck region and endobronchial localization is extremely rare. The treatment is usually resection alone or combination of surgery with radiotherapy. Herein we present a case of solitary endobronchial plasmacytoma which was resected with bronchoscopic electrocautery, because of extremely rare occurrence of solitary endobronchial plasmacytoma and also the successful outcome of bronchoscopic electrocautery therapy. 相似文献
