Clinical Summary

60 Y/O women with headache, Rt ear fullness, hearing loss and pulsatile tinnitus

Imaging Findings

MRI demonstrated a mass in Rt CP-angel with encasement of VII and VIII cranial nerve, petros bone destruction and Flow void focies (reperesenting hypervascularity).effusion in Rt mastoid is present. Extension of mentioned mass to jugular region is present.

Differential Diagnosis

• Chordoma,
• Otitis Media,
• Eosinophilic Granuloma (Histiocytosis X),
• Meningioma,
• Schwannoma,
• Neurofibroma,

Final Diagnosis

Glomus body tumor in CP-angel

Discussion (Related Text)

Glomus body tumors are rare, slow-growing, hypervascular tumors that arise within the jugular foramen of the temporal bone. They are included in a group of tumors referred to as paragangliomas, which occur at various sites and include carotid body, glomus vagale, and glomus tympanicum tumors
