Cerebellopontine angle lymphoma presenting as chronic mastoiditis

Area of Science:

• Otolaryngology
• Neurology
• Oncology

Background:

• Middle ear tumors are often misdiagnosed as mastoiditis.
• Early and accurate diagnosis is crucial for effective treatment.

Observation:

• A case of cerebellopontine angle non-Hodgkin's B-cell lymphoma presented with symptoms mimicking a middle ear inflammatory process.
• The initial presentation suggested a common middle ear infection.

Findings:

• The patient was diagnosed with non-Hodgkin's B-cell lymphoma, a rare cause of middle ear symptoms.
• The tumor's location in the cerebellopontine angle contributed to the diagnostic challenge.

Implications:

• Persistent or treatment-resistant mastoiditis warrants investigation for underlying neoplastic or other rare causes.
• This case underscores the importance of considering uncommon diagnoses in refractory ear conditions.
• Improved diagnostic strategies are needed to differentiate between inflammatory and neoplastic middle ear pathologies.
