ABSTRACT

Diagnosis: Chondrosarcoma of the skull base

History: 37 year old woman who presented with headaches.

Findings: Homogeneous mass centered in the right petro-clival fissure. Low signal on T1, high on T2, with marked homogeneous enhancement. There is also extension of the tumor through the skull base into the right nasopharynx, anterior to the longus colli muscle and compressing it. The lesion is also producing mass effect in the region of the fossa of Rosenmueller.

Ddx: Chondrosarcoma Chordoma (same MRI signal pattern but usually midline) Metastatic disease Plasmacytoma (usually low T2 on MRI) Lymphoma (usually lower signal on T2 and bright DWI) Adenoid Cystic Carcinoma (ACC) from nasopharynx

Dxhow: Biopsy

No MeSH data available.


Axial post contrast T1 with fat sat. Enhancing mass with areas of non enhacement likely representing chondroid matrix.
