An Unusual Location of a Primary Central Nervous System Lymphoma: The Temporal Horn

Abstract

Primary central nervous system lymphomas (PCNSLs) are commonly seen at the cerebral hemisphere, especially the corpus callosum, basal ganglia and thalamus. It is extremely rare for a PCNSL to occur in the temporal horn among pathology of intraventricular tumors. This patient was a 59-year-old man and referred our hospital due to confusion and gait disturbance. On the enhanced MRI, homogeneous-enhanced solitary mass was found within the temporal horn of the left lateral ventricle. That lesion was accompanied with increasing hypervascular tumor blush on the preoperative cerebral angiography. The author chose a craniotomy for removal of mass and tissue diagnosis and reported a patient with an extraordinary diagnosis of PCNSL at the temporal horn.
