Postpartum Pseudoadenomatous Hypophysitis Simulating a Pituitary Macroadenoma: A Case Report and Literature Review

Inflammatory hypothalamo-hypophyseal disorders are uncommon, representing only 1% of hypophyseal lesions. Among these, postpartum lymphocytic hypophysitis emerges as a particularly notable etiology. As a relatively recent entity, its recognition mandates a multidisciplinary approach to ensure preservation of compromised vital prognosis and amelioration of associated neuro-ophthalmologic and/or hypophyseal manifestations. We present a remarkable case of lymphocytic hypophysitis in a 32-year-old woman, unveiled during the postpartum period. Despite employing magnetic resonance imaging (MRI), preoperative diagnosis remained challenging. Surgical intervention became imperative due to progressive visual impairments. Postoperative course demonstrated favorable evolution, characterized by significant enhancement in visual acuity and normalization of cerebral MRI findings during follow-up.
