We report in this article the experience of the radiology department of the Hassan II University Hospital of Fez on 25 patients with a tumor of the PCA, over a period of 2 years, from January 2019 to December 2021. Clinical symptomatology consisted mainly of vestibular syndrome in 15 patients, headache in 8 patients, cerebellar syndrome in 5 patients and more rarely HTIC syndrome in 3 patients. An imaging assessment was performed, including a CT scan in 16 patients and all our patients had an MRI. A clinical-radiological-histological comparison allowed us to retain the diagnosis of certainty. The age of our patients ranged from 27 to 64 years, with a mean age of 45.5 years. Females were predominant (16F/9H) with a sex ratio of 1.7. The tumors identified were as follows: schwannoma (n=16), meningioma (n=6), epidermoid cyst (n=2), arachnoid cyst (n=1). The purpose of this work is to discuss the specific characteristics of CT and MRI imaging of the different tumors of the APC. Therefore, to show the importance of the different imaging methods in the diagnosis, therapeutic decision and monitoring.
