Posterior pituitary tumors: an entity unto itself.

Posterior pituitary tumors (PPT) are rare, benign tumors but may lead to compromised hypothalamic and pituitary function. A new study by Kremenevski et al. presents a single institution experience of these tumors, namely, pituicytomas, spindle cell oncocytomas, and granular cell tumors. They incorporate the revised 2022 WHO classification and highlight the preoperative and postoperative endocrine, metabolic, and radiologic outcomes of PPT. This study adds to our knowledge in this rare subset of tumors and underscores the need for ongoing surveillance for hypopituitarism and hypothalamic obesity.
