A total of 48 cases of tuberculous lesion in the lymph nodes (43 cases), lung (3 cases) and soft tissue (2 cases), was subjected to fine needle aspiration cytology(FNAC). The age of the patients ranged from 19 to 77 year-old (average 33.6 years in age) and the male to female ratio was 1: 4. Thirty-four cases (70.8%) demonstrated distinct granulomatous reaction with or without caseation necrosis, nine cases (18.8%) showed no granulomas, but large amount of necrotic debris with numerous polymorphonuclear cells and histiocytes, and five cases (10.4%) revealed acellular material only. The overall AFB positivity in smears was 62.5%. In areas associated with granulomatous reaction and necrosis, AFB positivity was 55.8%, while it was 80.0% in cases with acellular necrotic material. There were 2 cases of parasitic infestation which could not be easily differentiated from tuberculosis based on aspiration smears only.

A case of adenocarcinoma of cystic duct associated with GB empyema is presented. A 72 year old male was admitted to Kwangju Christian hospital because of abdominal pain in right upper quadrant for 4 days. He underwent explolaparotomy under the impression of GB empyema or GB cancer. For seeking causative factor of GB empyema, serial sections of cystic duct and mapping were performed. We can find adenocarcinoma of cystic duct in the specimen removed at cholecystectomy. The criteria for disgnosis of cystie duct carcinoma which was outlined by Farrar. These criteria are; 1) The growth must be restricted to the cystic duct, 2) There is no neoplastic process in the gall bladder, hepatic and common bile duct. 3) Histopathological examination must be comfirm carcinoma. Here we report a case of adenocarcinoma of cystic duct associated with GB empyema with brief review of Literature.

PURPOSE: To correlate histologic subtypes with MR signal intensity in meniagioma and to find etiologic factors responsible for the signal characteristics of T2WI. MATERIALS AND METHODS: We. reviewed MRIs and histopathologic studies in 35 cases of meningioma. MR signal intenisty was measured with respect to cerebral cortex(gray matter) as hypointense, isointense, or hyperintense. Pathologically, meningioma was classified into subtypes, acording to the new WHO classification of brain tumors. The degree of cellularity, collagen, and vascularity was graded from 1 to 3, and presence or absence of psammoma bodies, microcysts, micronecrosis and microhemorrhage was obeserved. Multiple linear regression analysis was done to find relationship between the pathologic findings and MR signal intensity of T2WI. RESULTS: Even in the same subtype, cellularity, collagen and vascularty of the tumor were different. T1WI was not useful in discriminating pathologic subtype because most tumors were isointense or hypointense to the cortex regardless of histologic type. Most tumors showed various signal intensity on T2WI, but T2WI were not useful, either. Exceptionally, all five cases of microcystic meningiomas were hyperintense on T2W1. In analysing the relationship between MR signal intensity and pathologic factor, increased collagen content produced decreased signal intensity(P<0.01) and the existence of microcyst resulted in high signal intensity(P<0.01). Cellularity, vascularity, microcalcification, micronecrosis and microhemorrhage had no relationship with signal intensity on T2WI. CONCLUSION: Except for the five microcystic meningiomas with hyperintenty on T2WI there was no relationship between MR signal intensity and subtype of meningiomas. Pathologic factors influencing T2 signal intensity were microcyst and collagen. Even in the same subtypes of meningiomas, the T2 signal intensity was different. This may be due to different ratio of microcyst and collagen.

PURPOSE: We designed this study to identify and suggest the reasonable timing of adjuvant radiotherapy in the treatment of uterine carcinosarcoma according to the surgical intent and patterns of progression. MATERIALS AND METHODS: We retrospectively analyzed a total of 50 carcinosarcoma patients diagnosed between 1995 and 2010. Among these 50 patients, 32 underwent curative surgery and 13 underwent maximal tumor debulking surgery. The remaining five patients underwent biopsy only. Twenty-six patients received chemotherapy, and 15 patients received adjuvant radiotherapy. RESULTS: The median follow-up period was 17.3 months. Curative resection (p < 0.001) and stage (p < 0.001) were statistically significant factors affecting survival. During follow-up, 30 patients showed progression. Among these, eight patients (16.0%) had loco-regional progression only. The patients who had received adjuvant radiotherapy did not show loco-regional progression, and radiotherapy was a significant negative risk factor for loco-regional progression (p = 0.01). The time to loco-regional progression was much earlier for non-curative than curative resection (range, 0.7 to 7.6 months vs. 7.5 to 39.0 months). CONCLUSION: Adjuvant radiotherapy in the treatment of carcinosarcoma might be related to a low loco-regional progression rate. Radiotherapy should be considered in non-curatively resected patients as soon as possible.

PURPOSE: Holmium laser enucleation of the prostate (HoLEP) is known to have a steep learning curve and, as a result, its clinical usage has limitations. The purpose of this study was to analyze the learning curve and early complications following the HoLEP procedure. MATERIALS AND METHODS: A retrospective analysis was performed on 161 patients who had undergone the HoLEP procedure for lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH) from July 2008 to September 2009. The procedure was done by two surgeons. Perioperatively, enucleated tissue weight, enucleation time, morcellation time, enucleation ratio (enucleation weight/transitional zone volume), and enucleation efficiency (enucleated weight/enucleation time) were analyzed, and early complications were assessed. RESULTS: Mean enucleation time, morcellation time, and enucleation ratio were 61.3 min (range, 10-180 min), 12.3 min (range, 2-60 min), and 0.66 (range, 0.07-2.51), respectively. In terms of efficiency, enucleation efficiency was 0.32 g/min (range, 0.02-1.25 g/min) and morcellation efficiency was 1.73 g/min (range, 0.1-7.7 g/min). Concerning the learning curve, enucleation efficiency was stationary after 30 cases (p<0.001), morcellation efficiency reached a learning curve at 20 cases (p=0.032), and enucleation ratio had no learning curve in this study. There were several cases of surgery-related complications, including bladder mucosal injury by the morcellator (13%), capsular injury during enucleation (7%), and conversion to a conventional resectoscopy procedure (15%), which showed a reduction in incidence with time. CONCLUSIONS: The learning curve of HoLEP is steep; however, it can be overcome gradually. Further study is necessary with respect to long-term postoperative follow-up.

PURPOSE: Prenatal sonography resulted in increased recognition of renal duplication anomalies and, therefore, earlier urological referral and evaluation. However, surgical approach in very young children is debating. We attempt to investigate clinical features and to propose the management strategies in patients with prenatally detected ureteroceles. MATERIALS AND METHODS: From 1982 to 1997, there has been 35 patients (47 units) of duplex system ureter in which both preoperative and postoperative imaging studies including DMSA renal scan were available. Among these, detailed diagnosis and treatment of prenatally detected (PreD) ureteroceles associated with duplex system (9 patients or 12 ureteroceles) were assessed compared with post-natally detected (PND) ones (26 patients or 35 ureteroceles). RESULTS: There were 2 males and 7 female patients in PreD group, whose ureteroceles presented as 6 unilateral (right 1, left 5) and 3 bilateral units. There were 3 patients (33%) presented with urinary tract infection in PreD group and 24 patients (92%) in PND group. Functional evaluation by DMSA renal scan revealed that 8 units (67%) were functioning in PreD group while 37% in PND group, which was not significantly different between two groups. Initial treatment in PreD group were performed in 11 units; transurethral ureterocele incision (TUI, 8 units), ureteroureterostomy (UUO, 1) and upper pole nephrectomy (UPNx, 2). Additional surgery was performed in 8 units, all of which were initially performed TUI. When initial functional status of the upper pole (UP) determined by renal scan were analyzed by ultimate mode of treatment, initially nonfunctioning parenchyme resulted in UPNx in 4 units and 8 functioning moiety were led to parenchyme-sparing surgery, implying TUI actually had not modified ultimate clinical course. Taken both PreD and PND together, UUO and ureteral reimplantation showed lower secondary operation rate. CONCLUSIONS: Although statistics did not fully support our clinical impression, patients with PreD ureterocele have higher proportion in preserving UP function compared with that of a PND. Our results shows direct approach to the upper pole according to the functional status is preferred.

Journal of the Korean Neurological Association 2015;33(4):306-309
Tumarkin's otolithic crisis refers to drop attacks that are an unusual manifestation of Meniere's disease. It has been proposed that these drop attacks result from mechanical deformation of the otolithic organs related to the endolymphatic hydrops that occurs in Meniere's disease, as revealed by MRI with intratympanic gadolinium enhancement. Here we report a patient with Tumarkin's otolithic crisis in whom inner-ear MRI with intratympanic gadolinium administration during the acute attack did not reveal the presence of endolymphatic hydrops.

PURPOSE: To assess relative diagnostic value of Ga-67 planar, Ga-67 SPECT, and CT images for detection of head and neck tumors and cervical lymph node metastasis. MATERIALS AND METHODS: Thirty eight patients of pathologically proven head and neck tumors including squamous cell carcinomas(n=32), malignant lymphomas(n=3), undifferentiated carcinomas(n=2), adenocarcinomas(n=l) were enrolled in this study. Ga-67 planar and SPECT images were obtained with intravenous injection of 5mCi of Ga-67 citrate. On the basis of 30 and 20 mm in the greatest diameter of cervical lymph nodes, we compared lesion detectability of Ga-67 planar, SPECT, and CT. RESULTS: Thirty eight cases of head and neck tumors were detected in 29 cases(76.3%) with Ga-67 planar image, 37 cases(97.3%) with Ga-67 SPECT, and 32 cases(84.2%) with CT. 25 of 32 squamous cell carcinomas were positive with Ga-67 planar image and all of 32 cases with Ga-67 SPECT. Both of two undifferentiated carcinomas were positive with Ga-67 planar and SPECT images. Two of three malignant lymphomas were positive with Ga-67 planar image and all of three with Ga-67 SPECT. Eight of nine tumors were negative with Ga-67 planar image and those were less than 30ram. One case of adenocarcinoma was negative with Ga-67 planar and SPECT images. Seven of nine lymph nodes greater than 30mm were positive with Ga-67 planar image and all of nine with Ga-67 SPECT. On the basis of 20mm in greatest diameter, 16 of 21 lymph nodes greater than 20 mm were positive with Ga-67 planar and SPECT images. CONCLUSION: CT providing better resolution than Ga-67 scan permitted analysis of size and location of metastatic cervical nodes, however primary tumors of oral cavity, vocal cord, and nasopharynx were often not detected on CT when metallic and motion artifacts were present, where Ga-67 SPECT was useful. Ga-67 SPECT enabled better anatomical localization than Ga-67 planar image and was useful in detection of lymph nodes greater than 30 mm.
