Skull metastasis from papillary thyroid carcinoma accompanied by neurofibromatosis type 1 and pheochromocytoma: report of a case.

We report here a 74-year-old woman with a skull metastasis from papillary thyroid carcinoma (PTC). In her medical history, she was diagnosed with neurofibromatosis type 1 (NF1) at age 28 years, and she underwent thyroidectomy for PTC at age 52 years and adrenectomy for pheochromocytoma (PC) at age 58 years. She was admitted to our hospital with an increased mass in the forehead.

Giant cell type of primary intracranial malignant fibrous histiocytoma: a case report.

The primary intracranial giant cell type of malignant fibrous histiocytoma (GC-MFH) is rare, and the resemblance to meningioma causes diagnostic confusion. Discrimination from meningioma bears important therapeutic and prognostic implications. We report one such case in which an extracranial malignant neoplasm was seen after the initial diagnosis and treatment.

Skull metastases from atypical pulmonary carcinoid tumor in a 19-year-old man.

A 19-year-old man presented with a rare skull metastasis from atypical pulmonary carcinoid tumor (APCT) manifesting as headache, diplopia, and cough. Head magnetic resonance imaging showed a skull base tumor extending from the posterior clinoid process to the clivus, and calvarial tumors in the right temporal and occipital bones. Chest and abdominal computed tomography showed a round tumor, 4 cm in diameter, in the lower lobe of the right lung and multiple small tumors in the liver.

Brain metastasis from small-cell neuroendocrine carcinoma of the urinary bladder: a case report.

Eight months after radical surgery for small-cell neuroendocrine carcinoma (SCNC) of the urinary bladder, a 69-year-old man was admitted with a brain tumor in the left frontal lobe. The tumor, about 5 cm in diameter, was intensely but heterogeneously enhanced on computed tomography and magnetic resonance imaging. The tumor was subtotally removed, leaving only the portion adjacent to the anterior horn of the left lateral ventricle.

Postoperative modified stereotactic radiotherapy using a micro-multileaf collimator in patients with malignant glioma.

To achieve local control of malignant glioma, we designed a postoperative stereotactic radiotherapy using a micro-multileaf collimator (micro-MLC). The purpose of this study was to clarify the feasibility of this treatment. The treatment was performed in six patients who met the following eligibility criteria: (1) supratentorial tumor, (2) residual tumor volume < or = 40 cm3, and (3) Karnofsky performance status > or = 70.
