However, a proportion of patients with these cysts will require cerebrospinal fluid shunting after tumor resection, despite resolution of the obstruction at the foramina of Monro. The goal of this study was to determine if colloid cyst size or preoperative ventricular volume predicted the need for postresection shunting.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>In a retrospective study design, ICD-9 codes 742.2 (colloid cyst) and 348.0 (brain cyst) were used to identify patients who had undergone resection of a colloid cyst at the University of Florida over the last 20 years. Preoperative imaging (CT or MRI) with a stereotactic software program developed at the University of Florida was used to measure volumes of the colloid cyst and the lateral ventricles. The relationships among ventricular volume, colloid cyst volume, and postoperative shunting were analyzed.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>The number of patients included in the study was 67, and their mean age was 37.7 years. Forty percent of the patients were female. Overall, 49.2% of the patients had a transcallosal approach, 35.8% a transcortical approach, and 14.9% an endoscope-assisted surgery. Mean preoperative ventricular volume was 76.5 cc in patients who never received a ventriculoperitoneal shunt (VPS) and 98.1 cc in those who were eventually treated with a VPS (p = 0.305). Patients with a postoperative VPS had an initial mean colloid cyst volume of 1.8 cc compared with 0.9 cc in patients without a VPS postoperatively (p = 0.019). Patients with colloid cysts larger than 0.6 cc (1-cm diameter) had a 12.8 increased odds of needing a VPS postoperatively (95% CI 1.81\u2013275).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Larger colloid cysts are associated with an increased need for postresection shunting independent of preoperative ventricular size. Prospective studies of patients with colloid cysts are necessary to further identify risks of permanent hydrocephalus.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2015.9.jns151183","type":"journal-article","created":{"date-parts":[[2016,1,29]],"date-time":"2016-01-29T15:03:24Z","timestamp":1454079804000},"page":"585-590","source":"Crossref","is-referenced-by-count":7,"title":["Do tumor and ventricular volume predict the need for postresection shunting in colloid cyst patients?"],"prefix":"10.3171","volume":"125","author":[{"given":"Kristin J.","family":"Weaver","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Florida, Gainesville, Florida; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"McCord","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Florida, Gainesville, Florida; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Neal","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Florida, Gainesville, Florida; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Bova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Didier","family":"Rajon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfredo","family":"Quinones-Hinojosa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Johns Hopkins University, Baltimore, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Rahman","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Florida, Gainesville, Florida; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns151183","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"1062","DOI":"10.3171\/jns.1998.89.6.1062","article-title":"Endoscopic treatment of colloid cysts of the third ventricle.
