Summary
A Rathke's cleft cyst, a rare pituitary cyst, was discovered in a teenage male. Surgical exploration revealed a colloid-filled cyst compressing the pituitary gland.
Area of Science:
- Neurosurgery
- Endocrinology
- Pathology
Background:
- An enlarged sella turcica was incidentally found in a 17-year-old male during imaging for facial trauma.
- The patient presented with hyposmia and left blindness, unrelated to pituitary dysfunction.
Observation:
- CT scan showed a non-enhancing hyperdense lesion within the sella turcica.
- Endocrinological evaluation revealed normal pituitary function.
- Surgical exploration via the transsphenoidal route was performed due to suspected non-functioning pituitary adenoma.
Findings:
- A cystic lesion filled with white mucous colloid material was identified, compressing the pituitary gland.
- Histological examination revealed a cyst wall composed of ciliated columnar epithelium with squamous metaplasia.
- PAS-Alcian blue staining confirmed the colloid material, and adjacent tubular gland-like structures were noted in the posterior pituitary.
Implications:
- This case highlights the importance of considering Rathke's cleft cysts in the differential diagnosis of sellar masses, even in young patients.
- The findings contribute to understanding the pathogenesis and radiological presentation of Rathke's cleft cysts.
- Surgical management via the transsphenoidal approach is effective for symptomatic Rathke's cleft cysts.
