Diagnosis of Pituitary Apoplexy

In this article, we will discuss the Diagnosis of Pituitary Apoplexy. So, let’s get started.

Diagnosis

  • Plain X-ray skull: It may show enlargement of sella turcica and destruction of clinoid processes. It can be normal also.
  • Pituitary CT/MRI scan: The CT scan of the head may show a high density or inhomogeneous gland with or without evidence of blood in subarachnoid space and MRI scan is more useful than CT scan in identifying pituitary hemorrhage or hemorrhage in a tumor with pituitary stalk deviation and compression of pituitary tissue
  • Angiography: It is done to differentiate pituitary apoplexy from subarachnoid hemorrhage due to aneurysmal rupture
  • Other hormone levels: Initially they may be normal except cortisol whose deficiency may develop acutely. Thyroid hormones (T3, T4, TSH) and gonadal hormone fall over weeks.
