Abstract

Sinonasal teratocarcinosarcoma (SNTCS) is a highly malignant and rare tumour characterised by a complex admixture of teratomatous and carcinosarcomatous components. In the head and neck area, it almost exclusively occurs in the sinonasal cavities; however, rare instances of nasopharyngeal and oral cavity involvement have been reported, with fewer than 100 cases reported in the literature.

Contribution: The contributed case involves the correlative CT, MRI and histopathology of a sinonasal teratocarcinosarcoma with intracranial involvement.

Keywords: Sinonasal teratocarcinosarcoma; computerised tomography; diffusion-weighted imaging; histopathology; intracranial; magnetic resonance imaging.
