Primary mucocele of the petrous apex: MR appearance.
نویسندگان
چکیده
Mucoceles of the petrous apex are rare. Their MR appearance varies depending on the degree of hydration or inspissation of the contents. Concise preoperative diagnosis is helpful, since mucoceles are better drained to the mastoids via an infralabyrinthine approach rather than the more risky middle cranial fossa approach used for cholesteatomas.

Petrous apex cephaloceles.
BACKGROUND AND PURPOSE Petrous apex cephaloceles (PACs) are uncommon lesions that are usually incidental but may be symptomatic. We reviewed MR and CT studies in 10 patients with PACs to identify characteristic imaging features that facilitate their diagnosis. METHODS MR and CT studies from 10 patients with PACs were reviewed retrospectively. In each case the PAC was characterized by lesion c...
متن کامل'Leave me alone' lesions of the petrous apex.
PURPOSE When troublesome MR imaging findings are noted in the petrous apex, the radiologist must determine if the area in question needs surgical therapy. Two nonsurgical entities, asymmetric fatty marrow and fluid-filled petrous air cells (trapped fluid), can be noted on conventional brain MR images and confused with pathologic lesions. Our observation that radiologists do not always confident...
متن کاملDilation of the subarachnoid spaces surrounding the cranial nerves with petrous apex cephaloceles in Usher syndrome.
Limited studies of brain MR imaging findings in Usher syndrome have reported atrophy with enlarged subarachnoid spaces. However, the specific appearance of the subarachnoid spaces surrounding the cranial nerves has not yet been described. Herein we describe the skull base MR imaging findings in an adult with Usher syndrome. Multiple cranial nerve exits were enlarged to the point of causing ceph...
متن کاملCholesterol granuloma of the petrous apex: MR and CT evaluation.
We reviewed the clinical, CT, and MR findings in seven consecutive patients who had a total of nine cholesterol granulomas. Preoperative MR scans were available for five of the seven patients; two patients were studied with MR after treatment only (one had a recurrent lesion and the other was asymptomatic at the time of study). Preoperative CT scans were available for all patients, except one p...
متن کاملMiddle ear cholesteatoma extending into the petrous apex: evaluation by CT and MR imaging.
CT and MR imaging findings were reviewed in four cases of acquired cholesteatoma of the middle ear that extended medially into the petrous apex and middle cranial fossa. In one case the lesion further extended anteromedially into the sphenoid sinus. CT demonstrated the lesions as nonenhancing hypodense masses with bone destruction, extending medially from the middle ear cavity to the petrous ap...
