Prognostic value of pretreatment contrast-enhanced computed tomography in esophageal neuroendocrine carcinoma: A multi-center follow-up study

Figure 3 A typical case of esophageal neuroendocrine carcinoma. A: Axial contrast-enhanced computed tomography image of a 75-year-old man with markedly enhanced esophageal neuroendocrine carcinoma in the middle segment of the esophagus (cT4N2M0). The patient showed a poor treatment effect from chemoradiotherapy with 3.6 mo and 8 mo of progression-free survival and overall survival, respectively; B: Sagittal-enhanced image of the patient. The tumor was 94.46 mm in length and exhibited moderate enhancement; C: Pathological specimen of the patient; D: Histological image of the patient.
