The typical distinction between cerebellopontine angle (CPA) medulloblastoma and other primary CPA tumors was not fully known. While CPA medulloblastoma is very uncommon, it should be included in the differential diagnosis of patients with CPA tumors. Medulloblastoma is a highly malignant brain tumor that most often occurs in children. These tumors are usually located in the vermis or fourth ventricle. Extra‐axial cerebellopontine angle (CPA) medulloblastoma is exceptionally rare. We describe a case of CPA medulloblastoma mimicking a schwannoma in a 6‐year‐old girl. Although the patient underwent many innovative magnetic resonance imaging (MRI) sequences, the corrected diagnosis was not initially established. The typical discrimination between CPA medulloblastoma and other primary CPA tumors was not fully clarified. This paper underscores that while CPA medulloblastoma is exceedingly rare, it should still be considered in the differential diagnosis of patients with CPA tumors.
