Summary

Spontaneous pneumocephalus, a rare delayed complication of mastoidectomy, occurred 37 years post-surgery. This case highlights the importance of considering pneumocephalus after middle-ear procedures.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Radiology

Background:

  • Middle-ear surgery, such as mastoidectomy, can have rare delayed complications.
  • Pneumocephalus, air within the cranial cavity, is a serious but infrequently reported sequela.

Observation:

  • A 43-year-old woman presented with spontaneous pneumocephalus 37 years post-mastoidectomy.
  • Clinical signs included cerebrospinal fluid leak, middle ear meningocele, and audible air entry into the cranium upon standing.
  • Radiological imaging revealed tegmen tympani destruction and temporal lobe pneumocephalus.

Findings:

  • The meningoencephalocoele and pneumocephalus were attributed to chronic pressure on a thinned tegmen tympani.
  • Surgical intervention via a combined middle-ear and subtemporal approach was performed emergently.

Implications:

  • Pneumocephalus should be recognized as a potential delayed complication following middle-ear surgery.
  • Advanced imaging (CT/MRI) is crucial for diagnosis, surgical planning, and understanding pathophysiology.
  • This case underscores the long-term risks associated with even routine otologic procedures.
