Summary
Rathke's cleft cysts (RCC) can spontaneously regress over time, even without treatment. These rare cases show that cysts can shrink significantly within 6 months to 1 year, highlighting the importance of observation.
Area of Science:
- Neuroendocrinology
- Radiology
- Neurosurgery
Background:
- Rathke's cleft cysts (RCC) are common sellar/suprasellar cysts.
- They originate from remnants of the Rathke's pouch.
- RCCs can cause symptoms due to mass effect or hormonal dysfunction.
Observation:
- Two patients with Rathke's cleft cysts (RCC) were observed.
- One patient had a 0.45 cm³ cyst, the other had a 0.71 cm³ cyst.
- Both cysts showed spontaneous volume reduction over 6 months to 1 year.
Findings:
- Spontaneous regression of Rathke's cleft cysts occurred in both cases.
- Cyst volume decreased significantly without any medical intervention.
- No neurological symptoms like headache or visual disturbance were reported during regression.
Implications:
- Spontaneous regression of Rathke's cleft cysts, though rare, is possible.
- Extended follow-up periods are crucial for monitoring RCCs.
- Conservative management with observation may be a viable option for select RCC cases.
