Teratoma rupture has been reported in various regions such as the omental sac, mediastinum, pelvic cavity, occipitocervical region, and sacrococcygeal area. To the best of our knowledge, rupture of intracranial teratoma has not been reported to date. We present a case of spontaneous rupture of a large intracranial teratoma. A 16-year-old female patient presented with six months history of headache and dizziness. Her medical history was unremarkable and she did not have any history of trauma. On examination, the left nasolabial groove was superficial and there was a decrease in the angle on the left side of her lips. The uvula deviated to the right side and there was a loss of pharyngeal reflex on the right side. She also had ataxia. Computed tomography (CT) scanning revealed a large lesion in the posterior fossa and the suprasellar region with a maximum diameter of 9.35 cm. This lesion was mostly composed of fat with attenuation value of -36 HU. The solid part of the lesion was heterogeneous in density with multiple calcifications or ossifications within it. Scattered "oil" was seen in the pontine cistern, bilateral cisterna ambiens, and bilateral ventricles, suggesting rupture of the tumor [Figure 1].
