AbstractGlomus tumours involving the middle ear and the cerebellopontine angle are reported with emphasis on audiological findings. Magnetic resonance imaging (MRI), angiographic and pathological results are presented. Audiological tests, including impedance audiometry, evoked otoacoustic emissions and auditory brainstem responses, are valuable in evaluation of the effect of glomus tumours on the auditory system as well as their pathological extent.

Immunodeficiency Syndrome

abstractMost necrotizing (malignant) external otitis (NEO) occurs in diabetic patients and is commonly caused byPseudomonas aeruginosa. We report an acquired immunodeficiency syndrome (AIDS) patient with NEO caused byAspergillus fumigatusin which computed tomography (CT) showed destructive petrous bone involvement and magnetic resonance imaging (MRI) of the ear discovered extensive soft tissue and facial nerve involvement. Dedicated MRI studies of the ear in this type of pathology provide new insights relating to nerve dysfunction, that cannot be obtained with CT.

Incomplete Partition

Computed tomographic scanning of the petrous bone and magnetic resonance imaging sequences of the inner ear and cerebellopontine angle of a deaf patient were performed to find an explanation for his deafness, and to establish whether he would be a good candidate for cochlear implantation. The imaging features were considered pathognomonic for incomplete partition type III (IP type III). Further management and discussion of this deafness subtype are detailed.

AbstractConcurrent occurrence of brain tumors in the same location is very unusual and has been noted in patients with neurofibromatosis. Two lesions, occurring in close contact but of different histology, are called contiguous tumors. Schwannoma and meningioma are the two common histologies reported to present as contiguous tumor. We present two patients with contiguous tumors in the cerebellopontine angle. The magnetic resonance imaging characteristics in both cases demonstrate important findings that should be identified to raise the possibility of contiguous tumors. We discuss the surgical implications in identifying the facial nerve in this complex tumor morphology and steps we took to preserve function. Variable displacement of the facial nerve in the presence of multiple tumors needs to be kept in mind during surgical management and can be significantly aided by intraoperative monitoring.
