Neuroendocrine carcinoma is a malignant tumor derived from nerve crest silver-loving cells, with rare onset, with the function of secreting bioactive peptide hormones and neuromediators, and is more likely to occur in the digestive tract, pancreas, bronchi and other parts

The imaging manifestations of neuroendocrine carcinoma are inspecific, and ultrasound shows that the lesions are mostly isoechoic or slightly elevated echo, and the demarcation from the surrounding normal tissue is not clear

PET-CT is an uneven increase in metabolism of 18F-FDG and is radioactive concentration
