[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.
