The intrauterine device (IUD) is a widely used contraceptive method. One of the most serious and rare complications of using an IUD is colon perforation. We report a case of colonoscopic removal of an IUD that had perforated into the rectosigmoid colon in a 42-year-old woman who presented with no symptoms. Colonoscopy showed that the IUD had penetrated into rectosigmoid colon wall and that an arm of the IUD was embedded in the colon wall. We were able to remove the IUD easily by using colonoscopy. The endoscopic approach may be considered the first choice therapy for selected patients.

A gastric intramural hematoma is very rare and commonly associated with trauma, anticoagulation therapy, coagulopathy, pancreatic disease, aneurysm and peptic ulcer disease. This is a case of gastric intramural hematoma which occurred in a patient taking aspirin after hypertonic saline-epinephrine injection for bleeding from a biopsy site. We describe a case of gastric intramural hematoma that was successfully managed with conservative therapy.

Numerous studies have demonstrated the clinical activity of temozolomide, a second-generation alkylating agent, against malignant brain tumors, however, its activity has not been reported in an Asian population. This study analyzed the efficacy and toxicity of temozolomide in 25 adult patients with recurrent or progressive malignant gliomas after surgery and standard radiation therapy with or without chemotherapy, enrolled in our institution since July 2000. Sixteen patients had glioblastoma multiforme (GBM), six with anaplastic astrocytoma, and three with anaplastic oligodendroglioma. Of the 25 patients, 3 (12%) achieved a complete response (CR), 8 (32%) achieved a partial response (PR), 6 (24%) had stable disease (SD), and 8 (32%) had progressive disease (PD). Two patients achieved a CR, 4 patients achieved a PR, 3 patients had SD and 7 patients had PD in GBM, and 1 patient achieved a CR, 4 patients achieved a PR, 3 patients had SD, 1 patient had PD in the non-GBM patients. Median progression free survival was 8 weeks in GBM and 22 weeks in the non-GBM patients. The median overall survival of each group was 17 weeks and 28 weeks. Temozolomide demonstrated moderate activity in recurrent and progressive malignant gliomas without serious toxicity.

The authors present the case of a patient who suffered from cerebellar dysfunction, radiographically documented brainstem compression, and neurological deterioration after proximal artery occlusion in a giant vertebral artery aneurysm. Symptom resolution was achieved after complete embolization of remained lumen of aneurysm. The cause of neurological deterioration is brainstem compression due to mass effect of the aneurysm. In order to avoid this fatal complication, it is necessary to determine appropriate therapy for the vertebral artery giant aneurysm by evaluating cerebral blood flow and other factors about growth of aneurysm.

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.

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.

So-called, the double channel pylorus has been, relatively rarely, reported through out the world. All reported cases were almostly those of gastroduodenal fistula as a complication of peptic ulcer disease. The congenital forms of double pylorus were reported even more rarely. We found three cases of double channel pylorus in 25,000 cases endoscopy done at our unit. All those three cases were thought to be acqired form endoscopically, radiographically and histologically. One of those was undergone to operative resection because of uncontrollable bleeding and the others were on medical theraphy with satisfaction.
