61 years Female Reason: Evaluate IACs History: Right Asymmetrical SNHL Provider Name: EMMANUEL J VILLEGAS EMMANUEL J VILLEGAS No abnormal foci of enhancement are appreciated within the internal auditory canals. The cochlea and semicircular canals appear intact. The cochlear nerve can be followed bilaterally tracking into the cochlea. The modiolus is well formed bilaterally.No abnormal enhancing lesions are appreciated at the cerebellopontine angle cisterns nor the internal auditory canals.There is right periorbital soft tissue swelling present adjacent to the right side, along the lateral (temporal) aspect of the right orbital rim which can also be identified on the prior exam from 4/25/2013. At that time it appeared to measure approximately 7 x 11 mm axial dimensions on the current exam it measures 24 x 13 mm axial dimensions. This appears to extend to the skin surface. It appears to extend into the right extraconal space. The extraconal involvement is not completely included on the current exam.
1.No abnormal lesions are identified in the internal auditory canals or inner ear structures to explain the patient's asymmetric sensorineural hearing loss. 2.There is redemonstration of a right periorbital soft tissue lesion which appears slightly larger on the current exam when compared to the prior exam from 2013. The lesion is not entirely included on this exam and as a result cannot be adequately assessed. A biopsy from 7/2/2013 indicates that this represents xanthogranulomatous inflammatory change.
