21-year-old woman with a cystic brain lesion.

摘要

A 21-year-old woman admitted to the hospital with severe headache. While driving, she suddenly could not feel the steering wheel in her right hand and experienced a feeling of getting lost. The symptoms subsided but followed by headache that gradually evolved into the worst headache in her life. Neurologic exam was normal and magnetic resonance imaging disclosed left parietal tumor with a large cystic component and enhancing mural nodule (Figure 1A). Differential diagnosis included ganglion ceil tumor (GCT), pleomorphic xan-thoastrocytoma (PXA) and pilocytic astrocytoma. The patient underwent left craniotomy with a complete resection of the tumor. Intraoperatively, the mass was intra-axial and consisted of a white-yellow firm 3 cm nodule located on a wall of a large cavity filled with an amber-colored fluid. There was no association with leptomeninges.
