ABSTRACT

Diagnosis: Cholesterol granuloma of the right petrous apex.

History: A 13-year-old girl presented with a 2-month history of intermittent right-sided headaches and diplopia. She described mild dysequilibrium but no hearing loss and had no

Findings: Abnormal hyperintense lesion in the far anterior petrous apex on the patient's right. Sharply marginated

Ddx: • Normal petrous fatty bone marrow • Cholesterol granuloma • Endolymphatic sac tumor

Dxhow: Endoscopic surgery

Exam: Physical examination demonstrated right-sided sixth nerve palsy. The remainder of the exam was within normal limits.

No MeSH data available.


The right petrous apex is expanded by a homogeneous, hyperintense mass.  On T1WI obtained without contrast (not available), the lesion is similar in appearance; in other words, there is not significant enhancement.  On T2WI (also not available), the lesion has high signal intensity.  On CT images (also not available) there is a thin rim of intact bone surrounding the lesion.
