A rare case of a mega mastoid antrum, an unusually large bony swelling in the temporal bone, is presented. This condition mimics other lesions and requires careful diagnosis, especially in patients without middle ear infection.

Area of Science:

  • Otolaryngology
  • Radiology
  • Pathology

Background:

  • Unilateral non-tender bony swelling in the mastoid region can indicate fibrous or bony lesions of the temporal bone.
  • Absence of middle ear infection symptoms is a key clinical feature.

Observation:

  • Radiological evidence of a large lucent area in the mastoid antrum without bony dehiscence.
  • A large lytic lesion in the mastoid segment of the temporal bone with an intact tympanic membrane.

Findings:

  • A mega mastoid antrum can present as a diagnostic dilemma, mimicking congenital cholesteatoma or eosinophilic granuloma.
  • This case highlights an unusually large mastoid antrum in a young adult with a cosmetic swelling and no middle ear suppuration.

Implications:

  • Accurate diagnosis of mega mastoid antrum is crucial for appropriate management.
  • Radiological findings and clinical presentation guide the differential diagnosis.
  • Further investigation may be needed to rule out other pathologies.
