Two challenging cases of pituicytoma

Area of Science:

• Neuro-oncology
• Endocrinology
• Neurosurgery

Background:

• Pituicytoma is a rare tumor originating from the neurohypophyseal pituicytes within the pituitary gland.
• This study presents two cases highlighting the diagnostic and therapeutic challenges associated with pituicytoma management.

Observation:

• Case 1: A 58-year-old female with decreased vision presented with a pituitary macroadenoma, diagnosed as pituicytoma via endoscopic endonasal approach (EEA) resection. Recurrence was noted at 1-year follow-up.
• Case 2: A 70-year-old female with a history of resected pituicytoma experienced tumor progression with cavernous sinus invasion, hydrocephaly, and panhypopituitarism, necessitating a transcranial approach. Recurrence was again observed, leading to consideration of radiotherapy.

Findings:

• Pituicytomas, despite being low-grade, demonstrate a propensity for recurrence, posing significant clinical challenges.
• Surgical resection via EEA or transcranial approaches are primary treatment modalities, but recurrence necessitates further intervention, including radiotherapy.

Implications:

• The rarity and potential for recurrence underscore the need for vigilant long-term surveillance in pituicytoma patients.
• Multidisciplinary management involving neurosurgery, endocrinology, and radiation oncology is crucial for optimizing outcomes in these challenging cases.
