Diagnostic and Treatment-Related Challenges in Sinonasal Teratocarcinosarcoma: A Report of Three Cases

Figure 4

Axial STIR, coronal, and axial postcontrast T1-weighted with fat saturation MR images of patient no. 3 with a T3N2bM0 tumor located in the right nasal cavity and sphenoid sinus. On the axial image, the primary tumor has an intermediate signal intensity. Note: due to obstruction by the tumor, the right maxillary sinus and the sphenoid sinus are filled with retained secretions displaying high signal intensity. The coronal image shows the enhancing tumor in the right nasal cavity just medial to the middle turbinate (arrow). Axial postcontrast image lower in the neck with a markedly enlarged lymph node in level II (fine needle aspiration cytology: TCS lymph node metastasis).
