Fine needle aspiration cytology of anaplastic meningioma

摘要

Meningiomas of the head and neck region are rare but well described on fine needle aspiration cytology (FNAC).1 Anaplastic meningioma is a rare WHO grade III intracranial tumour that has not been reported from extracranial sites or on FNAC. We describe here the cytological features of a case of anaplastic meningioma in a 15-year-old boy who underwent a subtotal resection with recurrence of multiple soft tissue swellings over the scalp, 2 months after surgery. FNAC performed from a scalp swelling showed a highly cellular aspirate composed of tumour cells arranged in loose clusters with prominent peri-vascular arrangement (Figure 1). The capillary-sized vessels were long and arborising with frequent branching.
