Summary
Tectal plate cysts, though rare in adults, can cause significant neurological issues like hydrocephalus and eye movement disorders. Surgical intervention led to neurological improvement in two reported adult cases.
Area of Science:
- Neuro-oncology
- Neurosurgery
- Ophthalmology
Background:
- Tectal plate cysts are exceptionally rare intracranial lesions.
- Secondary hydrocephalus can arise from tectal plate cysts.
- Adult presentations of tectal plate cysts are seldom reported.
Observation:
- Two adult patients presented with benign tectal plate cysts causing secondary hydrocephalus.
- Patient 1 exhibited complex eye movement abnormalities, including Collier's sign and nystagmus.
- Patient 2 presented with ataxia and impaired upward gaze.
Findings:
- Both patients underwent successful endoscopic fenestration of the tectal plate cyst and endoscopic third ventriculostomy.
- Neurological deficits significantly improved following the surgical procedures.
Implications:
- This report highlights the potential for tectal plate cysts to manifest in adults with distinct neurological symptoms.
- Endoscopic management offers a viable treatment option for these rare cysts.
- Distinguishing tectal plate cysts from other quadrigeminal cistern lesions is crucial for accurate diagnosis and treatment planning.
