PURPOSE: Through 13 cases of lacrimal ductal cysts which were diagnosed by clinical or histopathological findings, we investigated the clinical characteristic and the effect of cyst excision on lacrimal secretion. METHODS: As a primary treatment, cyst excisions(6 cases), marsupialzations(4 cases), and needle aspirations(3 cases) were performed and their results were compared. Pre-and postoperative lacrimal secretion tests(Schirmer I & BST) were performed on 10 cases which underwent cyst excision either primarily or secondarily(due to recurrences). A biochemical analysis of cyst fluid and serum IgA level was also done on 7 cases. RESULT: There were no recurrences on 6 surgically excised cases, but 1 out of 4 cases with marsupia-lizations and all 3 cases with needle aspirations recurred and underwent cyst excisions secondarily. Two out of 10 surgically excised cases showed reduced value of postoperative lacrimal secretion tests. Cyst fluid IgA levels were higher than that of serum in all 7 cases. CONCLUSION: The higher cyst IgA level may signify the presence of an active secretory precess within cyst walls. A complete cyst excision seems to be the best treatment choice for the prevention of recurren-ces and marsupialization is also considered as an alternative treatment modality. The cyst excision itself does not seem to affect lacrimal secretion.

PURPOSE: To report the effectiveness of Minocin sclerotherapy in the treatment of renal cysts. MATERIALS AND METHODS: We performed minocin sclerotherapy to 19 patients with 21 renal cysts composed of 17 cases of solitary renal cyst and three cases of multiple renal cyst and one case of polycystic kidney comfirmed by ultrasound and CT. After aspiration of cyst fluid, if the amount was less than 50ml, 500mg of minocin was mixed with 3ml of normal saline,if more than 50ml, 1000mg of minocin mixed with 5ml of normal saline were injected, and each case was followed-up over 3 months by ultrasound. RESULTS: Of all 21 renal cysts, 14 cases were followed-up three months after minocin sclerotherapy. In 12 of 14 cases, the size of the cysts decreased by 10% or collapsed completely. Of the remaining two cases, one collapsed after 6 months while the other recurred after 6months. Three cases were followed up after 20 months and only one of them recurred. 19 of all 21 cases(91%) were cured, and two of 21 cases(9%) were recurred. Pain was the only complaint. and four of 10'cases needed analgesics. CONCLUSION: Sclerotherapy with minocin has low recurrence-rate and low complication, and relatively early high cure-rate.

A case of intracerebral ependymal(neuroepithelial) cyst of developmental origin is presented. The cyst had no communication with ventricular system or subarachnoid space. The protein content of cyst fluid was higher than that of the CSF. The preoperative, postoperative CT scan and operative findings are presented. The authors reviewed and discussed the previously reported cases. .

We report on a rare case involving a 23-year-old female patient with mediastinal cystic mass complicated with acute pericarditis and cardiac tamponade. Pericardial fluid demonstrated lymphocyte-predominant exudate and the level of carcinoembryonic antigen (CEA) was unexpectedly elevated. Successive aspiration of mediastinal cystic mass revealed a very high level of CEA (>100,000 U/mL) and carbohydrate antigen 19-9 (>15,000 ng/mL). This patient was clinically diagnosed as an infected bronchogenic cyst complicated with pericarditis and cardiac tamponade. The treatment resulted in alleviation of her symptoms.

Intraductal papillary mucinous neoplasm is frequently found recently and have recognized as precancerous lesions to pancreatic cancer that characterized by papillary growth of the ductal epithelium with rich mucin production and cystic dilatation of the main pancreatic duct and/or its branches. These tumors are asymptomatic and often multifocal. Preoperative differentiation between benign and malignant lesions is important to select the most appropriate treatment and to improve prognosis. Surgical resection is the treatment of choice to avoid malignant transformation when predictive factors for malignancy are present. These factors include mural nodule in the cyst, main pancreatic duct dilation, thick septum, cyst greater than 3 cm, atypias in the cyst fluid and the presence of symptoms. The follow-up of these patients who do not undergo surgical resection, is of great importance, since patients with IPMN appear to be at risk for pancreatic cancer. Patients who retain a portion of their pancreas following resection of an IPMN need to be followed up with periodic imaging to detect recurrences and metachronous lesions.

PURPOSE: To evaluate MR imaging findings of degenerating parenchymal neurocysticercosis and to determine the characteristics which distinguish it from other brain diseases. METHODS: MR imagings of 19 patients (56 lesions)of degenerating parenchymal neurocysticercosis were retrospectively evaluated, focusing on the size and locationof lesions, signal intensity patterns of cyst fluid and wall, the extent of the surrounding edema and features of contrast enhancement. RESULTS: Degenerating parenchymal neurocysticercosis was located in gray or subcortical white matter in 89.3% of 56 lesions(50/56); most of these (98.2%) were smaller than 2cm in diameter. Cyst fluidsignal was hyperintense relative to CSF on T1 and proton density weighted images (92.9%). A hypointense signal rimof the cyst wall was noted in the lesions on proton density (92.9%) and T2 weighted (98.2%) images. Surrounding edema was mostly mild. Peripheral rim enhancement was noted in all lesions, and this was frequently irregular and lobulated (67.9%) with a focal defect in the enhancing rim (41.1%). CONCLUSION: Findings which could be helpfulin distinguishing degenerating parencymal neurocysticerosis from other brain diseases are as follows : small, superficial lesions ; hyperintense signal of the cyst fluid on T1 and proton density weighted images ; hypointense signal of the cyst wall on proton density and T2 weighted images ; relatively mild extent of surrounding edema,and peripheral rim enhancement which is frequently irregular and lobulated with a focal defect in the enhancingrim.

PURPOSE: Sclerotherapy is performed additionally to improve the outcome of aspiration in simple renal cyst. Ethanol has been used most commonly as a sclerosing agent, however, drainage is necessary which complicates the procedure. For this reason, we used minocycline HCl as a sclerosing agent without need to be drained and evaluated the results. MATERIALS AND METHODS: From June 1990 to May 1999, 140 patients who underwent percutaneous minocycline HCl sclerotherapy for simple renal cyst were evaluated. Among them, 10 patients were missed during follow-up and 7 patients had bilateral simple renal cysts. The simple renal cysts were aspirated under ultrasonography, and then minocycline HCl 100mg mixed with 5ml normal saline was injected into the cyst per 50ml of aspirated cyst fluid. The follow-up ultrasonography was performed at posttreatment 3, 6 and 12 months. The recurred cases were retreated with same procedure. RESULTS: Among 137 renal cysts of 130 patients who could be followed up, 70 renal cysts (51.1%) were totally collapsed and 53 renal cysts (38.7%) showed a 50% or more decrease in cyst volume after first treatment. All 14 persistent renal cysts (10.2%) showed a 50% or more decrease in cyst volume after second or third treatment. Catheterization for drainage of the sclerosing agent was not needed. There were only some minor complications such as nausea, vomitting and local pain that subsided within one day with only symptomatic treatment. CONCLUSIONS: These results shows that percutaneous minocycline HCl sclerotherapy is simple, safe and effective and can be a alternative first line therapy of simple renal cyst.

We assessed cyst fluid of 14 cases of simple renal cyst. The aspirates were analyzed for color, lipid. protein, glucose, lactic acid dehydrogenase(LDH), amylase, electrolytes and Papanicolaou smears and cell blocks were performed. A clear amber fluid with minimal lipid content, LDH lower than that of blood and a normal cell pattern on Papanicolaou stain and cell block which are characteristics of transudate were seen in all cases. Although the number of cases are insufficient, it would appear that the content of simple renal cyst is identical to that of transudate.
