title: [Lymphangioma--a rare cause of a space-occupying lesion at the base of the skull].
abstract: A case of an extremely rare lymphangioma of the sphenoid sinus in a 58-year-old woman is described in order to discuss the histogenesis, histopathology, and clinical symptomatology of lymphangiomas located in the base of the skull. The clinically silent course for many years is typical, as is the onset of acute symptoms after bleeding into the tumour. The therapy of choice is to achieve decompression. Prior to this, an aneurysma or a hemangioma should be excluded by fine-needle puncture or by puncture cytology.
