Third epidermoid tumors are a rare finding. The appearance of these tumors often makes them difficult to diagnose, and thus they require multimodality imaging.
A 48-year-old male patient reported to our hospital with complaints of vomiting and severe headache. The patient also complained of involuntary micturition for the past five days. We used a combination of computed tomography (CT) and magnetic resonance imaging (MRI) imaging modalities to confirm the presence of a malignant epidermoid cyst arising from the third ventricle. A contrast-enhanced CT of the head demonstrated minimal perilesional enhancement while an MRI revealed a large, lobulated and septated T2 hyperintense mass arising from the third ventricle. The maximum size of the lesion measured 73 mm × 65 mm × 64 mm in size.
Malignant epidermoid arising from the third ventricle in an adult male was reported using a combination of CT, MRI, and MR spectroscopy.
Core tip: The use of multi-modality imaging can help radiologist diagnose uncommon tumors in unusual sites. The combination of computed tomography, magnetic resonance imaging, and MR spectroscopy was useful in confirming the diagnosis of malignant epidermoid arising from the third ventricle, an unusual site in routine practice.
