Background
Colloid cyst is a benign rare lesion that originates in the third ventricle. Headache, vomiting,
visual deterioration, and memory deficits are the most common presenting symptoms.
Endoscopic excision of colloid cyst is one of the recent advances in the field of minimally
invasive neurosurgery.
Aim
The aim was to assess the efficacy and safety of the endoscope for excision of the colloid cyst.
Patients and methods
In this study, we review our experience in 14 patients who presented to us in two University
Hospitals in south of Egypt in 2 years (2016 and 2017). The authors used LOTTA ventriculoscope
with HOPKINS wide-angle straightforward telescope 6°.
Results
Of fourteen patients, 13 (92.9%) improved completely postoperatively, and only one (7.1%)
patient who had visual deterioration did not improve after surgery. Total to near-total excision
was done in 11 (78.6%) patients, and evacuation of the cyst with partial excision was done
in three (21.4%) patients.
Conclusion
Endoscopic excision of third ventricular colloid cyst is a safe minimally invasive approach that
can be used in patients who present with colloid cyst without the need to do cerebrospinal
fluid diversion (shunt).
