Abstract

Context: Colloid cyst is a rare tumour of the brain that has a good outcome
upon surgical removal. Aims: We present the outcome of surgical management of colloid cyst
at our setup based on the experience of last ten years. Study Design, Setting and Period: The
type of study is a retrospective review of cases of third ventricular colloid cyst operated at the
Department of Neurosurgery, Civil Hospital Karachi, Pakistan, from January 2005 to December
2015. Methods and Material: The patient’s data including the clinical records, radiographic
data, operative and follow up notes were studied. The patient population was divided into
groups based upon the size of the cyst. The surgical approaches utilized were the transfrontal
transventricular and transcallosal approach. All the patients also underwent a series of tests to
determine the function of the somatosensory, motor and memory functions both pre and post
operatively and upon follow up. Statistical analysis used: Data was analyzed using SPSS
version 23. Mean and standard deviation was used for continuous variables, while frequency
and percentage was used for categorical variables. Results: The study population n= 60
patient, n= 36 males and n= 24 females. The size distribution of the cyst was, n= 4 (6.66%)
were less than 1.5cm, n=47 (78.33%) were 1.5-3cm and n=9 (15%) were >3cm. Headache
was the most common presenting complaint. Papilledema was observed in 71.66% of the
patients, while memory changes were observed in 8.33% of the patients. The surgical excision
of the cyst was performed in n= 52, patients while ventriculoperitoneal shunt was performed in
n= 8 patients. Conclusions: According to the results of our study the transcallosal approach, is
a safe technique, in which the neurological damage is limited due to minimal callosotomy and
manoeuvring of the fornix.
