The CT and MRI observations of small cell neuroendocrine carcinoma in paranasal sinuses. SNEC of paranasal sinuses in a 41-year-old man (a-d). The lesion was symmetrical, and the size was about 5.8 cm × 5.7 cm × 4.3 cm. (a) CT image showed worm-eaten bone destruction in sphenoid sinus, anterior cranial fossa, and orbital apex; however, bone contours still could be seen. (b) T1-weighted MR image demonstrated isointensity. (c) T2-weighted MR image demonstrated isointense together with a ‘pigeon’ pattern. (d) Contrast-enhanced T1-weighted MR image demonstrated a moderate heterogeneous enhancement mass, which showed involvement of the pharyngonasal cavity, orbital apex, pterygopalatine fossa, sella, cavernous sinus, internal carotid canal, and jugular foramen.

The CT and MRI observations of small cell neuroendocrine carcinoma in paranasal sinuses. SNEC of paranasal sinuses in a 53-year-old man (a-d). The tumor size was about 4.3 cm × 4.1 cm × 3.1 cm. (a) CT image showed worm-eaten bone destruction in the right ethmoidal sinus and fossa orbitalis; however, bone contours still could be seen. (b) T1-weighted MR image demonstrated isointensity. (c) T2-weighted MR image demonstrated isointense mixture. (d) Contrast-enhanced T1-weighted MR image demonstrated a mild heterogeneous enhancement mass, which showed involvement of the pharyngonasal cavity and fossa orbitalis.
