Luc's abscess is an extremely rare complication of otitis media, caused by the spread of the middle ear infection to the subperiosteal area and its accumulation beneath the temporal muscle. Unlike other subperiosteal abscesses relating to otitis media, infection may not be associated with mastoid bone involvement. Therefore, it is defined as a benign complication of otitis media. However, its rare occurrence may lead to delayed diagnosis and treatment. Here we report a case of an 11-year-old boy diagnosed with Luc's abscess with mastoid involvement. We discuss its clinical presentation and treatment with a review of the literature.
