Hemangioblastoma is uncommon, accounting for 1 to 2.5% of all primary neoplasms of the central nervous system. Ten to 20% of hemangioblastomas occur as part of Von Hippel-Lindau disease(VHL). Multiple hemangioblastomas are seen only with VHL and these are seen in up to half of VHL-associated hemangioblastomas. We have treated two cases of multiple hemangioblastomas associated with VHL disease in a family, sister(case I, 48/female) and her brother(case II, 41/male). Both patients had renal and pancreatic cysts in addition to CNS hemangioblastomas. Their hemangioblastomas were removed totally, and then their neurological symptoms had Improved. With a review of the literature, the authors present a family of VHL-associated multiple hemangioblastomas.

OBJECTIVE: Spontaneous intracranial hypotension(SIH) is a rare condition presented with cardinal postural headache and low CSF pressure. The authors describe the characteristic clinical features, imaging findings, and treatment methods in the patients with spontaneous intracranial hypotension. METHODS: Between May 1994 and Aug. 2001, eight patients were diagnosed with spontaneous intracranial hypotension based on characteristic radiologic and clinical findings in our department. All cases were shown diffuse meningeal enhancement(DME) on magnetic resonance(MR) image. Two cases had subdural hematoma. RESULTS: The most characteristic feature on Brain MR image is DME with/without subdural fluid collection. Radionuclide image reveals direct leaking point and rapid appearance of urinary bladder activity. Direct leaking points were detected in all four cases who performed radioisotope study. Autologous epidural blood patches were applied to four cases, and all of them were improved without complication. Among four patients treated with conservative method, three were improved, but one patient was died of spontaneous chronic subdural hematoma. CONCLUSION: We suggest that 1) meticulous studies need to be performed aggressively if SIH is diagnosed clinically and radiologically, 2) the most effective study may be radioisotope study, and 3) if leaking point is found, aggressive management such as autologous epidural blood patches is recommended.

BACKGROUND: This nationwide survey was undertaken to characterize the general pathological features of colorectal cancer in Korea, and especially to elucidate the geographical characteristics by means of their anatomical distribution. METHODS: We analysed 1,676 colorectal cancers (from 1,602 patients) surgically resected in 1998 at 15 institutions from nine geographical sites in Korea. RESULTS: The topographic incidence of colorectal cancer in seven out of the total nine geographical sites, was the highest in the rectum (32-54%); and those from Wonju and Cheongju were in the sigmoid colon (28% for both). The right colon cancer incidence was 42% in Wonju and 36% in Cheongju, while it was 17-22% in the other areas. The cecal cancer incidences in Wonju and in Taegu were 7% and 8%, respectively, but 0-4% in the other areas. As for histology, moderately differentiated adenocarcinoma was the most frequent (46-84%), except for in Wonju and Chonju, where the most predominant type was well differentiated (63% and 52%, respectively). CONCLUSION: The incidence of right colon cancer was higher in Wonju and Cheongju, than in the other geographical sites. The cecal predilection was prominent in Taegu and Wonju. The Elucidation of geographical differences in degree of differentiation for tubular adenocarcinoma seems to require further cumulative study with strict guidelines.
