A lateral supratentorial location of such cysts is extremely rare. A unique case of a lateral supratentorial endodermal cyst that required surgical intervention due to uncal herniation, complicated with postoperative seizures, is presented.<\/jats:p>\n<\/jats:sec>\n\nCase Description:<\/jats:title>\nA 48-year-old man presented with transient motor aphasia and diplopia. Magnetic resonance imaging showed a cystic lesion occupying the left frontal and temporal convexity with midline shift and uncal herniation. Cyst resection was performed, and cyst contents with mucous-like components were aspirated. Histopathological examination showed an endodermal cyst. The patient showed no neurological deficits immediately after surgery but developed tonic-clonic seizures 9 h after surgery. Sedation and intubation were required to control the seizures. After administering multiple antiepileptic drugs, he was extubated on the 5th<\/jats:sup> day after surgery. He was discharged home in a month with mild impairment in dexterity of his right hand.<\/jats:p>\n<\/jats:sec>\n\nConclusions:<\/jats:title>\nSurgical intervention for endodermal cysts can be complicated by postoperative seizures caused by chemical irritation of brain cortex due to spillage of cyst contents. It is important to irrigate the cyst wall very well intraoperatively and pay attention not to spill the cyst fluid to unaffected locations. Preoperative administration of antiepileptic drugs should also be considered if endodermal cysts, not simple arachnoid cysts, are suspected preoperatively.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_259_2019","type":"journal-article","created":{"date-parts":[[2019,8,25]],"date-time":"2019-08-25T11:46:15Z","timestamp":1566733575000},"page":"141","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Resection of a lateral supratentorial endodermal cyst complicated by postoperative seizures: A case report"],"prefix":"10.25259","volume":"10","author":[{"given":"Keisuke","family":"Nagata","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery, Tokyo Metropolitan Police Hospital, 4-22-1 Nakano, Nakano-ku, Tokyo, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Kiyofuji","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery, Tokyo Metropolitan Police Hospital, 4-22-1 Nakano, Nakano-ku, Tokyo, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Munehiro","family":"Yokoyama","sequence":"additional","affiliation":[{"name":"Departments of Diagnostic Pathology, Tokyo Metropolitan Police Hospital, 4-22-1 Nakano, Nakano-ku, Tokyo, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeo","family":"Sora","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery, Tokyo Metropolitan Police Hospital, 4-22-1 Nakano, Nakano-ku, Tokyo, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2019,7,19]]},"reference":[{"key":"10.25259\/SNI_259_2019\/ref-1","doi-asserted-by":"crossref","first-page":"128","DOI":"10.1007\/s10014-012-0114-0","article-title":"Symptomatic suprasellar endodermal cyst, possibly originating from the seessel\u2019s pouch, containing fluid with a high carcinoembryonic antigen level","volume":"30","author":"Akimoto","year":"2013","journal-title":"Brain Tumor Pathol"},{"key":"10.25259\/SNI_259_2019\/ref-2","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1016\/j.wneu.2016.08.089","article-title":"Neurenteric cyst or neuroendodermal cyst?
