Leptomeningeal metastasis with sturge-weber syndrome-like gyriform calcification on imaging: a case report

This case presented diagnostic challenges due to extensive gyriform calcification and the "tram-track" sign, which occasionally resemble SWS. However, the patient's late onset, absence of prior calcification, and lack of facial hemangioma were atypical for SWS. Furthermore, non-dominant hemisphere calcification did not align with aphasia symptoms. This single-case observation demonstrates that LM may present with radiologically heterogeneous features, and emphasizes the necessity of histopathological confirmation for accurate diagnosis.
