Labyrinthine sequestrum, a rare inner ear infection, differs from labyrinthitis ossificans. Early CT and MRI scans are crucial for diagnosis and preventing complications.

Area of Science:

  • Otolaryngology
  • Radiology
  • Pathology

Background:

  • Labyrinthine sequestrum is a rare condition distinct from labyrinthitis ossificans.
  • It presents with unique clinical, radiologic, and histologic features.

Purpose of the Study:

  • To describe the characteristics of labyrinthine sequestrum.
  • To highlight diagnostic imaging and management strategies.

Main Methods:

  • Case series of 4 patients with labyrinthine sequestrum.
  • Involved clinical and laboratory investigations, CT, MRI, surgical procedures, and pathological evaluation.

Main Results:

  • Patients presented with otorrhea, otalgia, tinnitus, and profound hearing loss.
  • Imaging revealed osteolytic masses with calcified debris and erosion of the bony labyrinth.

  • Pathology showed inflammatory granulation tissue with calcification or osseous tissue.

    • Conclusions:

    • Labyrinthine sequestrum is attributed to chronic osteomyelitis with osteonecrosis.
    • Prompt CT and MRI, along with optimal management, are essential for diagnosis and preventing fatal complications.
