Diagnostic Importance of Computed Tomography and Magnetic Resonance Imaging in Coalescent Mastoiditis, a Severe Complication of Acute Otitis Media

Coalescent mastoiditis, a severe form of acute mastoiditis, involves the breakdown of bony septae in the mastoid air cells, leading to abscess formation and potential intracranial complications. Despite its rarity due to antibiotic use, timely diagnosis is critical. Computed tomography (CT) is essential for detecting bone erosion, while magnetic resonance imaging (MRI) is superior for evaluating soft tissue involvement and intracranial extensions. This case report describes a 32-year-old male with coalescent mastoiditis successfully managed with intravenous antibiotics and abscess drainage, highlighting the crucial role of imaging in guiding treatment and preventing severe complications.
