Objective: The aim of this study was to evaluate the cochlear nerve diameter in patients with unilateral sensorineural hearing loss and to compare the diameter of the normal side with the hearing loss side. Materials and Methods: A total of 36 patients with idiopathic unilateral sensorineural hearing loss were included in the study. Magnetic resonance imaging (MRI) and audiogram were performed on all the patients. Both cochlear nerve diameters were measured on axial thin-section constructive interference in steady state (CISS) sequences. Results: The patients comprised 16 males and 20 females with a mean age of 52.3±13.7 years. Hearing loss was in the right ear in 11 patients, and in the left ear in 25. The average cochlear nerve diameter on the side with hearing loss was 0.13 cm while it was 0.19 cm on the normal side. There was a statistically significant difference between the two sides (p lt; 0.001). Conclusion: In patients with unilateral sensorineural hearing loss, MRI allows the assessment of the cochlear nerve with anatomic detail, and enables the exclusion of possible organic pathologies. Demonstration of decreased cochlear nerve diameter in idiopathic sensorineural hearing loss will contribute to elucidating the etiology of this disease in the future.

Ascariasis is a common parasitic infection caused by ascaris lumbricoides infestation. Although it is mostly seen in the intestines, it may occasionally be seen in the gallbladder. It generally presents with symptoms of right upper quadrant pain. Radiological imaging is very useful in diagnosis. Albendezol or mebendazole may be used in treatment. The case is here presented of a 22-year old male patient radiologically diagnosed with gallbladder ascariasis.
