3rd ventricular colloid cyst,Transcortical aproach

29 year old female presented with drowsy and comatose condition 3 months back, urgent CT brain was s/o gross hydrocephalus with 3rd ventricular colloid cyst. She was immediately operated with VP shunt and she became conscious postop. She was electively posted for excision of colloid cyst. Colloid cyst is benign colloid/ mucinous cyst of third ventricle which blocks foramen of monro causing acute hydrocephalus and can cause sudden death. Vp shunting is only emergency measure and cyst has to be removed because shunt may block anytime and despite of shunt colloid cyst can cause sudden death. There are two aproaches to open colloid cyst surgery interhemispheric transcallosal and transcortical. Transcortical aproach might be difficult in shunted patients because of difficulty in finding ventricle. In this patient i had chosen transcortical route and kept transcallosal route as standby option incase i dont find ventricle easily, luckily i found ventricle in first puncture. Gradual excision of colloid cyst was done. Nice intraoperative vdo with audio explanation has been sent kindly have a look. Post op patient had no neurodeficit and was discharged in 6 days. Preop post op scans, images of pathology are shared.
