title: Primary extra-cranial meningioma following total hip replacement.
abstract: A 61-year-old man presented with pain at the left hip and decreased mobility 10 years after total hip replacement. Imaging demonstrated a large destructive expansile mass adjacent to the prosthesis. Histological analysis confirmed the presence of an extra-cranial meningioma. Primary tumours after total hip replacement are rare and include soft tissue sarcomas, bone sarcomas and lymphomas. To our knowledge, no previous cases of primary extracranial meningioma have been identified. The imaging features, histology, pathogenesis and differential diagnosis are discussed.
