[Acromegaly and symptoms of the motor apparatus].

In this case report, a 72-year-old woman presented with symptoms attributed to arthritis, and MRI indicated sacroiliitis. However, the patient also experienced enlargement of hands and feet in addition to sweating and snoring, which in combination with coarse facial features suggested acromegaly. This diagnosis was biochemically confirmed, and MRI revealed a pituitary adenoma, which was successfully removed by transsphenoidal surgery. Symptom relief and reduced swelling occurred immediately post-operatively. Acromegaly can masquerade as arthritis or osteoarthritis, which may delay diagnosis.
