Keywords CPA tumours; diagnosis
Description The correct diagnosis of CPA tumours is a relatively common issue in both neurological and ENT practice, the omission of which can have serious consequences for the patient. Properly set clinical guidelines and diagnostic protocols are key aspects of good clinical practice. In the case of CPA tumours, two options are available: the first is diagnosis with the help of an ABR as the primary tool for determining the group of patients with a possible tumour; the second is an MRI scan of the posterior cranial fossa. With an appropriately set diagnostic protocol in place, and despite the 40% chance of failure of the ABR to detect tumours less than or equal to 1 cm, similar treatment results can be achieved with much higher cost efficacy in case of primary ABR testing.
