Cholesterol granuloma (CG) may erode into the middle ear, the mastoid bone and the petrous apex. However, aggressive erosion into the cranial cavity is extremely rare. Here we report a case of huge CG extending to the middle cranial fossa. Temporal bone computerized tomography showed a soft tissue mass which destroyed the bony plate of the posterior and middle cranial fossa. On magnetic resonan...

INTRODUCTION Gradenigo's syndrome is nowadays a rare condition characterized by a triad of otorrhea, facial pain with trigeminal nerve involvement and abducens nerve palsy. Most cases are caused by medial extension of acute otitis media into a pneumatized petrous apex and surgical drainage is usually the treatment of choice. We present a case highlighting the pathological mechanism of this dise...

ninges. Analyses of the cerebrospinal fl uid were normal including cytology. Multiple lytic lesions of the cranium were also found. A computerized tomography (CT) scan confi rmed the erosion of the left petrous apex as well as multiple bone lesions. Full examination of the patient’s blood yielded normal results. Mammography showed only fi brocystic breast disease. A CT scan did not reveal metas...

OBJECTIVES/HYPOTHESIS While there are many benefits to the endoscopic endonasal approach to the infratemporal fossa, involvement of the petrous portion of the internal carotid artery (ICA) poses a unique challenge. The endoscopic endonasal approach requires establishing the relationship of the petrous ICA to anatomical landmarks to guide the surgeon. This study evaluates the relationship of pet...

Submit Manuscript | http://medcraveonline.com characterized for having a cystic pattern containing cholesterol crystals that are usually surrounded by foreign body giant cells. Their growing pattern is very variable and it is related to the frequency and severity of the micro hemorrhages happening within. It can be found in different locations in the temporal bone such as in the petrous apex (P...

Most necrotizing (malignant) external otitis (NEO) occurs in diabetic patients and is commonly caused by Pseudomonas aeruginosa. We report an acquired immunodeficiency syndrome (AIDS) patient with NEO caused by Aspergillus fumigatus in which computed tomography (CT) showed destructive petrous bone involvement and magnetic resonance imaging (MRI) of the ear discovered extensive soft tissue and f...
