Radiology · Neuroimaging: meningioma

Sample item

A woman has a slowly growing extra-axial mass with broad dural attachment, homogeneous contrast enhancement and a thickened enhancing 'dural tail', with adjacent hyperostosis. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Meningioma

Meningiomas are the commonest benign extra-axial tumours, and often show calcification, CSF cleft sign, dural tail and bony hyperostosis. They are more common in women, and can be associated with NF2. Surgical resection is curative in many cases.

Option by option

  • A. Meningioma (correct)

    Correct. A dural-based mass with a dural tail and hyperostosis is a meningioma.

  • B. Metastasis from lung

    A metastasis is intra-axial and usually multiple.

  • C. Medulloblastoma

    Medulloblastoma arises in the cerebellum of children.

  • D. Glioblastoma

    Glioblastoma is intra-axial and necrotic.
