Summary

Inferior petrosal sinus sampling (IPSS) can help diagnose Cushing's disease. However, a rare but serious complication of brain stem ischemia highlights the need to carefully consider its use.

Area of Science:

  • Endocrinology
  • Neurology
  • Neurosurgery

Background:

  • Inferior petrosal sinus sampling (IPSS) is a diagnostic procedure to confirm pituitary-dependent Cushing's disease.
  • It aids in localizing microadenomas before transsphenoidal surgery.

Observation:

  • A 14-year-old boy experienced a severe complication following IPSS.
  • The complication involved brain stem ischemia, leading to abducens nerve palsy and hemiparesis (Raymond's syndrome).

Findings:

  • This case highlights a rare but significant risk associated with IPSS.
  • The event underscores the potential for serious neurological complications.

Implications:

  • The findings necessitate a re-evaluation of the indications for performing IPSS.
