Sheehan's syndrome is one of the common causes of hypopituitarism among women in developing countries, although its incidence in developed countries is declining owing to well- advanced obstetric care.
Sheehan's syndrome, first described by Sheehan in 1937,4 is a postpartum hypopituitarism caused by necrosis of the pituitary gland.
The diagnosis of Sheehan's syndrome was established in the background of appropriate history and hormonal studies and pituitary magnetic resonance images corroborated it by demonstrating a normal-sized sella that was empty with no pituitary parenchyma inside.
Sheehan's syndrome refers to postpartum hypopituitarism as a result of pituitary necrosis occurring during severe hypotension or shock secondary to massive bleeding during or just after delivery.
In view of symptoms of hypothyroidism dating back to her last delivery, which was associated with PPH, she was investigated for possible Sheehan's syndrome Hemogram revealed anemia of microcytic hypochromic type with normal counts.
Because of this, an absence of PRL rise after thyrotropin-releasing hormone (TRH) is considered to be the most sensitive screening test in patients with Sheehan's syndrome (8).
