[Intracranial dural malignant lymphoma: case report].
A case of intracranial dural malignant lymphoma was presented. A 35-year-old woman was admitted with generalized seizure. The neurological findings and laboratory data were normal. Computed tomography (CT) showed a nodular lesion in the left frontal convexity with marked enhancement by contrast medium. Angiography showed a slight tumor stain and the feeding artery from the ethmoid artery. On surgery, a soft pinkish tumor was found to be located in the dura and subdural space. It was resected subtotally. The histological diagnosis was malignant lymphoma of B cell origin. Postoperative Ga scintigraphy and abdominal CT disclosed no abnormalities in other organs, but bone marrow examination revealed lymphoma cells, which suggested that the patient might have systemic lymphoma. The patient and her family refused additional treatment. The patient is alive and well now over six years after the craniotomy. Primary central nervous system (CNS) lymphomas usually arise in the cerebral parenchyma, while secondary CNS lymphomas commonly involve leptomeninges and perivascular spaces. Mass lesions arising in the dura are very rare.
