Often asymptomatic, they can manifest as midline swelling, headaches, seizures, or cerebral ischemia. Recognition and management are crucial for mitigating complications and ensuring favorable patient outcomes.<\/jats:p>\n <\/jats:sec>\n \n Case Description:<\/jats:title>\n A 14-year-old girl presented with swelling at the occiput for 3 months. Initial imaging was suggestive of an extra-dural abscess in the occipital region with surrounding bone erosion. An infectious workup, including tests for tuberculosis, was non-contributory. A suboccipital craniectomy was done. On lifting, the bone flap, thick, purulent, and sebaceous contents with hair were spotted, which was adherent to the inner table of the skull and the dura overlying the torcular herophili, suggesting an infected dermoid cyst. A near-total excision was done, and culture-directed antibiotics were given. Postoperatively, the child made a complete recovery.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The diagnosis of a dermoid cyst must be kept in mind, and it should be considered in the differential diagnosis of midline posterior fossa lesions. The risk of postoperative recurrence from incomplete excision should be weighed against the risk of injuring the venous sinuses during the extensive resection of dermoid cysts adherent to the torcular region.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_490_2024","type":"journal-article","created":{"date-parts":[[2024,11,15]],"date-time":"2024-11-15T09:44:05Z","timestamp":1731663845000},"page":"412","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An infected intracranial dermoid cyst at the region of torcular herophili: A case report"],"prefix":"10.25259","volume":"15","author":[{"given":"Soumya","family":"Pahari","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Shree Birendra Hospital, Kathmandu, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paawan Bahadur","family":"Bhandari","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shree Birendra Hospital, Kathmandu, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muna","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Medicine, Nepalese Army Institute of Health Sciences, College of Medicine, Kathmandu, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Purushottam","family":"Baniya","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Shree Birendra Hospital, Kathmandu, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deekshya","family":"Devkota","sequence":"additional","affiliation":[{"name":"Department of Medicine, Nepalese Army Institute of Health Sciences, College of Medicine, Kathmandu, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rahul","family":"Jha","sequence":"additional","affiliation":[{"name":"Department of Surgery, Nepalese Army Institute of Health Sciences, College of Medicine, Kathmandu, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prarthana","family":"Subedi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Nepalese Army Institute of Health Sciences, College of Medicine, Kathmandu, Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2024,11,15]]},"reference":[{"key":"10.25259\/SNI_490_2024\/ref-1","doi-asserted-by":"crossref","first-page":"226","DOI":"10.1016\/j.ijsu.2020.10.034","article-title":"The SCARE 2020 guideline: Updating consensus surgical case report (SCARE) guidelines","volume":"84","author":"Agha","year":"2020","journal-title":"Int J Surg"},{"key":"10.25259\/SNI_490_2024\/ref-2","first-page":"104","article-title":"Cerebral dermoid tumours","volume":"19","author":"Arseni","year":"1976","journal-title":"Neurochirurgia"},{"key":"10.25259\/SNI_490_2024\/ref-3","doi-asserted-by":"crossref","first-page":"e241","DOI":"10.1097\/SCS.0000000000006184","article-title":"Midline intranasal dermoid cyst with intracranial extension: technical details of a multidisciplinary approach to a rare condition","volume":"31","author":"Davis","year":"2020","journal-title":"J Craniofac Surg"},{"key":"10.25259\/SNI_490_2024\/ref-4","first-page":"71","article-title":"The torcular herophili (confluence of sinuses)","volume-title":"Tubbs imaging and surgery of the intracranial dural venous sinuses","author":"Granger","year":"2020"},{"key":"10.25259\/SNI_490_2024\/ref-5","doi-asserted-by":"crossref","first-page":"308","DOI":"10.1016\/S0028-3843(14)60047-5","article-title":"Ruptured intradiploic dermoid cyst overlying the torcular herophili","volume":"44","author":"Gulsen","year":"2010","journal-title":"Neurol Neurochir Pol"},{"key":"10.25259\/SNI_490_2024\/ref-6","doi-asserted-by":"crossref","first-page":"10","DOI":"10.33552\/ANN.2021.11.000765","article-title":"Infected dermoid cyst of the posterior fossa: Case report","volume":"11","author":"Hammoud","year":"2021","journal-title":"Arch Neurol Neurosci"},{"key":"10.25259\/SNI_490_2024\/ref-7","doi-asserted-by":"crossref","first-page":"414","DOI":"10.3109\/02688697.2013.841846","article-title":"Intradiploic dermoid cyst: A rare cause of intracranial hypertension","volume":"28","author":"Hashemi","year":"2014","journal-title":"Br J Neurosurg"},{"key":"10.25259\/SNI_490_2024\/ref-8","first-page":"bcr0820103245","article-title":"Intradiploic epidermoid cyst overlying the torcula: A surgical challenge","volume":"2011","author":"Khan","year":"2011","journal-title":"Case Rep"},{"key":"10.25259\/SNI_490_2024\/ref-9","first-page":"54","article-title":"A rare case of intracranial dermoid cyst in a young woman-a case report","volume":"10","author":"Kumar","year":"2023","journal-title":"Arch Integr Med"},{"key":"10.25259\/SNI_490_2024\/ref-10","doi-asserted-by":"crossref","first-page":"39","DOI":"10.1016\/0090-3019(90)90170-T","article-title":"Dermoid cysts of the posterior cranial fossa in children.
