    This case report details a rare pituitary choristoma, initially misdiagnosed as a pituitary adenoma. Histological examination confirmed the choristoma, highlighting its distinct nature and diagnostic challenges.

    Area of Science:

    • Endocrinology
    • Neurosurgery
    • Pathology

    Background:

    • Choristomas are rare congenital tumors composed of histologically normal tissue found in an abnormal location.
    • Pituitary choristomas, particularly those in the suprasellar or neurohypophyseal region, are exceptionally uncommon.

    Observation:

    • A patient presented with symptoms suggestive of a chromophobe pituitary adenoma.
    • Initial clinical presentation and radiological findings were consistent with a pituitary adenoma.
    • Histological examination was crucial for the definitive diagnosis of a posterior pituitary lobe choristoma.

    Findings:

    • The patient underwent surgery with a satisfactory post-operative course despite advanced age.
    • Post-operatively, endocrine and visual function disturbances remained largely unchanged.

  • This case represents the twentieth reported instance of suprasellar or neurohypophyseal choristoma in the literature.

    • Implications:

    • This case underscores the importance of histological examination for diagnosing rare pituitary tumors.
    • Understanding the clinical presentation, radiology, and treatment of pituitary choristomas is vital for accurate diagnosis and management.
    • Further discussion on the histiogenesis and nature of these rare tumors is warranted to improve clinical outcomes.
