The most important differential diagnosis is the third ventricular craniopharyngioma. To the best of the authors\u2019 knowledge, there have been few cases of xanthogranulomatous variant colloid cysts reported in the English literature.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 77-year-old white woman presented with headaches, memory loss, and abnormal gait for the past 4 months. Magnetic resonance imaging revealed a solid cystic lesion measuring 3.0 cm\u00d72.8 cm\u00d72.9 cm located inside the anterior portion of the third ventricle causing obstructive hydrocephalus. The posterior portion of the lesion was predominantly solid and hypointense on T2 and T1, with areas of post- contrast enhancement, and the anterior portion was predominantly cystic with both hyper- and hypointense areas on T1 and T2, with no suppression on fluid-attenuated inversion recovery and no restriction to diffusion. The patient underwent a left frontal craniotomy with pterional approach, and the lesion was removed microsurgically.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Xanthogranulomatous reaction is rarely described in colloid cysts, which happens as a response to desquamation of epithelial lining, subsequent lipid accumulation, and as tissue inflammatory response to intracystic hemorrhage. Microsurgical resection is the treatment of choice. As compared to the plain colloid cyst, these lesions are difficult to fully excise as the inflammatory reaction to the xanthomatous material leads to adhesions to adjacent structures; therefore, the aspiration of cystic contents without spillage is advisable to achieve maximal resection of cyst walls.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_179_2019","type":"journal-article","created":{"date-parts":[[2019,8,30]],"date-time":"2019-08-30T13:08:02Z","timestamp":1567170482000},"page":"169","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Xanthogranulomatous colloid cyst: Radiologic\u2013 pathologic correlation and diagnostic difficulties"],"prefix":"10.25259","volume":"10","author":[{"given":"Matheus D.","family":"Soldatelli","sequence":"first","affiliation":[{"name":"Departments of Radiology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"},{"name":"Departments of Neuroradiology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francine Hehn","family":"de Oliveira","sequence":"additional","affiliation":[{"name":"Departments of Neuropathology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Am\u00e1lia Izaura Nair","family":"de Medeiros Klaes","sequence":"additional","affiliation":[{"name":"Departments of Radiology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"},{"name":"Departments of Neuroradiology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael Sodr\u00e9","family":"da Silva","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital Sao Francisco de Paula, Pelotas, Brazil"},{"name":"Departments of Neurosurgery, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1pio Cl\u00e1udio","family":"Martins Antunes","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marino Muxfeldt","family":"Bianchin","sequence":"additional","affiliation":[{"name":"Departments of Neurology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana \u00c1vila","family":"Duarte","sequence":"additional","affiliation":[{"name":"Departments of Radiology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"},{"name":"Departments of Neuroradiology, Hospital de Cl\u00ednicas de Porto Alegre, Porto Alegre, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2019,8,30]]},"reference":[{"key":"10.25259\/SNI_179_2019\/ref-1","doi-asserted-by":"crossref","first-page":"183","DOI":"10.4103\/0976-3147.112761","article-title":"Xanthogranulomatous colloid cyst of the third ventricle","volume":"4","author":"Alugolu","year":"2013","journal-title":"J Neurosci Rural Pract"},{"key":"10.25259\/SNI_179_2019\/ref-2","doi-asserted-by":"crossref","first-page":"256","DOI":"10.1016\/0090-3019(81)90048-3","article-title":"Mixed colloid cysts-xanthogranulomas of the third ventricle","volume":"16","author":"Antunes","year":"1981","journal-title":"Surg Neurol"},{"key":"10.25259\/SNI_179_2019\/ref-3","doi-asserted-by":"crossref","first-page":"24","DOI":"10.4103\/2152-7806.92932","article-title":"Acute hemorrhage in a colloid cyst of the third ventricle: A rare cause of sudden deterioration","volume":"3","author":"Carrasco","year":"2012","journal-title":"Surg Neurol Int"},{"key":"10.25259\/SNI_179_2019\/ref-4","doi-asserted-by":"crossref","first-page":"343","DOI":"10.1007\/BF00690969","article-title":"Xanthogranulomatous colloid cyst of the third ventricle","volume":"66","author":"Hadfield","year":"1985","journal-title":"Acta Neuropathol"},{"key":"10.25259\/SNI_179_2019\/ref-5","first-page":"221","article-title":"Colloid cyst xanthogranuloma of the third ventricle a case report","volume":"39","author":"Kudesia","year":"1996","journal-title":"Indian J Pathol Microbiol"},{"key":"10.25259\/SNI_179_2019\/ref-6","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1016\/0090-3019(85)90308-8","article-title":"Mixed colloid cyst-xanthogranuloma of the third ventricle.
