Pituitary Microadenoma Presenting With Varied Endocrine Manifestations: A Case Series of Four Female Patients Aged 19–39 Years

Pituitary microadenomas are small, generally non-malignant lesions under 10 mm in size, arising in the anterior pituitary. Despite their small size, these lesions may cause a broad range of clinical manifestations depending on their hormonal activity or mass effect. Magnetic resonance imaging (MRI) is instrumental in diagnosis, often demonstrating hypo- or isointense lesions on T1-weighted sequences with minimal or delayed enhancement. This case series highlights Four patients presenting with distinct symptoms, including amenorrhea, galactorrhea, and visual deficits, underscoring the critical role of MRI in early identification and management.
