meningioma mimicking cavernous malformation: a case report and review of the literature. Contrast-enhanced axial T1-weighted image revealing a heterogeneous contrast-enhancing lesion in the subcortical white matter of the right parietal lobe and no apparent dural attachment.
papillary meningioma of brainstem: case report and literature review. Preoperative magnetic resonance imaging demonstrating a cystic-solid mass of brainstem with mild edema. The solid part manifested homogeneous enhancement on T1-weighted gadolinium enhancement (thick arrow). The well-defined mass was mainly located in pons with the cystic part (thin arrow) extending to the right cerebral peduncle, but there was no evidence of attachment to dura mater. Axial T1-weighted imaging (A), coronal (B) and sagittal (C) post-contrast T1-weighted imaging.

These can occur at various sites but usually occur in the head and neck region.
