[A case of foreign-body granuloma].

A 24-year-old male patient was admitted to our Ryukyu University Hospital, complaining of visual disturbance. He had had partial removal of a suprasellar region tumor in another hospital one year before the admission. Microscopical findings had shown two cell patterns of germinoma in the first operation. Following it, the patient received irradiation with a total dose of 54Gy. The tumor completely disappeared after these procedures. On this admission, plain CT scan revealed an isodensity mass in the suprasellar cistern extending to the right side of the third ventricle, which was enhanced homogeneously. In MRI, the mass showed low intensity in the T1-weighted inversion recovery sequence, and heterogeneously, high intensity in the T2-weighted spin echo sequence. By bifrontal craniotomy, the tumor was removed. Histologically, it consisted of granuloma containing fine cotton fibers. MRI findings of intracranial foreign-body granuloma were discussed.

[Cerebrospinal fluid transfer of cefbuperazone in the blood-brain barrier lesions of neurosurgical patients].

Cefbuperazone (CBPZ) was given in 15 patients after surgery. There was no infections except for 1 case in which signs of infections were suspected. As side effects, slight elevations in hepatic transaminase levels were observed in 3 patients during the CBPZ chemotherapy. CBPZ concentrations in 7 patients were studied. The subjects were divided into 3 groups according to CT finding during the chemotherapy to correlate CBPZ concentrations to degrees of blood-brain barrier lesions; Group I: no enhancement, Group II: mild or focal enhancement, Group III: diffuse and marked enhancement. It was interesting to note that the more marked enhancement were obtained, the higher levels of CSF concentration of CBPZ.

[Chronic subdural hematoma following advanced cancer: report of three cases].

Three cases of chronic subdural hematoma (CSH) following advanced cancer are reported. Case 1. A 54-year-old male patient was referred to our clinic in a semicomatose state. Bilateral CSH was evacuated through a pair of burr holes, and consciousness was recovered. However, subependymal hemorrhage occurred at the third ventricle 6 days after the operation. Hematological examination revealed thrombocytopenia. He died 12 days after operation because of hemorrhage in the lung. Postmortem examination disclosed metastatic adenocarcinoma of unknown origin to the dura mater, lymph nodes, lung and bone marrow. Case 2. A 50-year-old male patient who was diagnosed as having gastric cancer was referred to our clinic in a state of deep coma. CT scan revealed CSH and putaminal hemorrhage at the left side. Hematological examination revealed disseminated intravascular coagulation (DIC). After the subdural hematoma was evacuated, the putaminal hematoma enlarged and hemorrhagic infarction at the left temporo-occipital lobes occurred. He died 2 days after operation. Autopsy was not carried out, but histological examination revealed poorly differentiated malignant cells in the outer membrane of the subdural hematoma. Case 3. A 53-year-old female patient who had a history of gastric cancer operated on 4 years ago was admitted to our clinic complaining of headache and vomiting. CT scan revealed bilateral subdural hematoma. Following a pair of burr-holes and irrigation of the hematoma, hemorrhage recurred alternatively at the left side on the 6th and at the right side on the 27th day after the operation. Hematological examination revealed DIC, and bone marrow puncture disclosed metastasis of the adenocarcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)

Enterogenous cyst in the cervical spinal canal. Case report.

The case of an 11-year-old Japanese girl with an intradural and extramedullary enterogenous cyst is presented. A mass giving a low-intensity signal in comparison with the spinal cord was demonstrated on magnetic resonance imaging. Histologically, the diagnosis was confirmed on specimens stained with periodic acid-Schiff, alcian blue, mucicarmine, and immunohistochemical staining of carcinoembryonic antigen, and by electron microscopy.

[Moyamoya disease associated with persistent primitive trigeminal artery--a case report and review of literature].

A case of moyamoya disease associated with the persistent primitive trigeminal artery (PTA) is reported. 5 such cases reported in literature are reviewed. A 16-year-old female patient was admitted to our clinic, having complained of right hemiparesis for 8 years. CT scan revealed multiple low density areas in the left frontal, temporal and parietal lobes. In left carotid angiogram, the internal carotid artery was occluded at the C3 portion and basal moyamoya (stage IV) was found. In right carotid angiogram, the internal carotid artery was occluded at the C3 portion and basal moyamoya (stage V) was found. Furthermore the persistent primitive trigeminal artery was seen with marked moyamoya vessels from the posterior cerebral artery. In vertebral angiogram, the posterior cerebral artery was seen bilaterally with moyamoya vessels. In 133Xe-rCBF study, compared with the mean flow in each hemisphere, the flow decreased at the temporal lobe, but, in contrast, increased at the parieto-occipital lobes. Reviewing the literature, the following conclusions are suggested. 1. Persistent primitive trigeminal artery will promote the stage of moyamoya disease. 2. It will protect the brain from hemorrhage and/or ischemia in moyamoya disease.

[A case of calcified intracranial tuberculoma presenting unique MRI findings].

A 41-year-old male patient was admitted in our Ryukyu University Hospital complaining of parosmia. He had a history of miliary tuberculosis 21 years ago. Neurologically he showed left anosmia and hyperreflexia of the right upper extremity. Plain skull X-P and CT scan revealed a calcified mass, 25mm in diameter, at the left frontal base. In MRI, the mass showed isointensity using the T1 weighted inversion recovery sequence and heterogenously low intensity using the T2 weighted spin echo sequence. Surgery was performed by bifrontal craniotomy. Then the tumor was removed totally including two coexisting small tumors. Histologically, they consisted of calcified caseous tissue and thick collagen capsule, suggesting old calcified tuberculomas. Postoperative course was uneventful and did not result in meningitis. Antituberculous therapy of streptomycin, isoniazid and rifampin was given for 2 weeks, started on the operative day. MRI findings were presented in detail and the guideline of antituberculous therapy to the tuberculoma was discussed.
