“…We found 80% (4/5) noted the evidence of rupture, and only 20% (1/5) had no evidence of gross rupture. 7,[11][12][13] In our case, there were small areas of hyperintensity out of the lesion capsule on T1WI and T2WI, suggesting fat signal. The imaging features can demonstrate focal rupture of the cyst capsule.…”

BACKGROUND Dermoid cyst is a rare benign tumor exhibiting a typical radiological pattern and most commonly located along the midline. Laboratory examination was always normal. However, the features of some rare cases are atypical that can be easily misdiagnosed as other tumors. OBSERVATIONS A 58-year-old patient presented with tinnitus, dizziness, blurred vision, and gait unsteadiness. Laboratory examination showed the serum levels of carbohydrate antigen 19-9 (CA19-9) were significantly increased (186 U/mL). A computed tomography (CT) scan revealed a predominant hypodense lesion in the left frontotemporal region with a hyperdense mural nodule. The lesion appeared as an intracranial extradural mass with a mural nodule on the sagittal image, displaying mixed signal on T1- and T2-weighted imaging. A left frontotemporal craniotomy was performed for cyst resection. Histological results confirmed a diagnosis of dermoid cyst. No tumor recurrences were observed at the 9-month follow-up. LESSONS Extradural dermoid cyst with a mural nodule is extremely rare. When a hypodense lesion on CT shows mixed signal on T1- and T2-weighted imaging with a mural nodule, even if it is located in the extradural areas, it is important to consider a dermoid cyst. Serum CA19-9 combined with atypical imaging features may contribute to the diagnosis of dermoid cysts. Only recognition of atypical radiological features can avoid misdiagnosis.

“…Cranial dermoid cysts are rare, and to the best of our knowledge, there are only 10 previously published cases (Table 1) [4][5][6][7][8][9][10][11][12]. They occur near the midline and arise from epithelial cells abnormally retained during the closure of the neural tube during embryologic development.…”

Cranial dermoid cysts are rare, embryologic tumors containing fat, hair, and other ectodermal elements. They occur most frequently in the posterior fossa and are typically diagnosed as incidental findings on brain imaging done for an unrelated reason. Traumatic rupture of a previously unidentified intracranial dermoid cyst can mimic symptoms of post-concussion syndrome and should be ruled out with magnetic resonance imaging (MRI). Surgical intervention after traumatic rupture may not result in complete symptom control due to the persistence of dermoid cyst debris in the subarachnoid space. Here, we present the clinical scenario and radiological features of a ruptured dermoid cyst due to trauma, highlighting a rare complication of a classically benign lesion.
