Severe fibromyalgia after hypophysectomy for Cushing's disease

Area of Science:

• Endocrinology
• Rheumatology
• Pain Medicine

Background:

• Cushing's disease is a condition caused by excess cortisol.
• Hypophysectomy is a surgical procedure to remove the pituitary gland.
• Fibromyalgia is a chronic disorder characterized by widespread pain.

Observation:

• A patient with Cushing's disease underwent hypophysectomy.
• Following surgery, the patient presented with symptoms consistent with fibromyalgia.
• Clinical examination identified tender points at 12 of the 18 criteria sites for fibromyalgia.

Findings:

• The case suggests a potential link between hypophysectomy and the onset of fibromyalgia.
• The patient met the American College of Rheumatology 1990 criteria for fibromyalgia classification.
• The exact cause of fibromyalgia remains unknown, but hormonal and pain modulation pathways are implicated.

Implications:

• This case highlights a possible iatrogenic cause of fibromyalgia.
• Further research is warranted to explore the relationship between pituitary surgery and fibromyalgia.
• Understanding the role of endorphin secretion and pain modulation after hypophysectomy may inform future pain management strategies.
