Sinonasal teratocarcinosarcoma mimicking chronic invasive fungal disease of paranasal sinuses

Sinonasal teratoid carcinosarcoma or teratocarcinoma is an extremely rare aggressive tumour. It usually arises in the nasal cavity and paranasal sinuses. In this study, the authors described magnetic resonance imaging and computed tomography findings from a patient with sinonasal teratocarcinoma. Computed tomography of the sinonasal teratoid carcinosarcoma can mimic paranasal fungal infections. Magnetic resonance imaging is a very useful tool for making a differential diagnosis between the sinonasal teratoid carcinosarcoma and paranasal sinusitis.

Sinonasal teratocarcinosarcoma treated with surgery followed by volumetric modulated radiotherapy: a case report with review of literature

Surgical excision along with use of postoperative radiotherapy forms an integral management of sinonasal teratocarcinosarcoma (SNTCS). However, given the rarity of the tumor, no standardised guidelines, dose, technique and target delineation exist especially in the era of modern radiation delivery techniques. This is a case of 55-year-old male diagnosed as SNTCS treated with radical ethmoidectomy followed by volumetric modulated radiotherapy, showing good local control and acceptable toxicity profile.
