ABSTRACT

Diagnosis: Endolymphatic Sac Tumor

History: A 54-year-old woman presented with chronic ear pain.

Findings: "Bipolar" mass involving the petrous bone and posterior fossa Destructive petrous (temporal bone) mass - posteromedial, near vestibular aqueduct - extends to middle ear - erosion includes right sigmoid area - heterogeneous mixed cystic and solid - hyperintense on both T1W and T2W - proteinaceous and/or hemorrhagic fluid

Ddx: Endolymphatic sac tumor "Heffner tumor" cystic and papillary adenocarcinoma Chondroid tumor Chondroma/Chondrosarcoma Chondromyxoid fibroma Other destructive petrous masses cholesterol granuloma epidermoid metastasis

Dxhow: resection, pathology and histology

No MeSH data available.

MR images demonstrate an irregular multilobulated and heterogeneous (partially cystic and partially solid) mass involving the petrous portion of the temporal bone. On the T1-weighted images, the mass has high signal intensity. On the T2-weighted images, there are curvilinear serpentine hypointensities, suggestive of vessels, hemosiderin deposition, or calcification. Some of the right petrous mastoid air cells are fluid filled.
