Non-Hodgkin diffuse large B-cell lymphomas of the mastoid that extend from the nasopharynx are extremely rare in children. Moreover, in lymphoproliferative diseases, the presence of otoneurological signs prior to systemic disease involvement is rare. Here, we present a rare case of non-Hodgkin B-cell lymphoma invading the middle ear and mastoid in a 1-year-old boy that mimicked acute mastoiditis with complete facial nerve palsy. As this case illustrates, physicians should consider a diagnosis of malignant lymphoma if a patient presents with otitis media and mastoiditis accompanied by facial palsy.

Cerebral venous thrombosis as a manifestation of paraneoplastic angitis and otitis media, revealing non-Hodgkin B-cell lymphoma (NHBL), is extremely rare. A 57-year-old woman presented with headache, auditory disturbance and recalcitrant otitis media. Magnetic resonance imaging showed brain edema in the temporal lobe and transverse sinus thrombosis. External drainage under antibiotic treatment was repeated based on a diagnosis of invasive otitis media and mastoiditis associated with infectious sinus thrombosis, but the condition deteriorated progressively. Open surgery for otitis media was performed 6 years after the initial symptoms and after a tumorous lesion had been detected in the middle ear. Pathological findings revealed NHBL. We report a rare case of NHBL presenting as otitis media and mastoiditis associated with sinus thrombosis, and a literature review.

Extra nodal presentation of Non Hodgkins Lymphoma (NHL) is a rare entity, and data available about the NHL that primarily involves of middle ear and mastoid is limited. We report a case of diffuse large B cell lymphoma (DLBCL), in a 2 year 8 month old boy, who developed otalgia and facial palsy. Computed tomography revealed a mass in the left mastoid. Mastoid exploration and histopathological examination revealed DLBCL. This case highlights the importance of considering malignant lymphoma as one of the differential diagnosis in persistent otitis media and/facial palsy.
