   Case Report Top


A 60-year-old gentleman with known diagnosis of ileocecal neuroendocrine tumor (NET) underwent right hemicolectomy with ileocecal anastomosis. On 68-Gallium DOTANOC-PET/CT scan, multiple somatostatin receptor positive hepatic lesions were detected. Incidentally, a well defined fat density lesion was found in the left lung.

[Figure 1] shows axial CT and fused PET/CT images showing a left intrathoracic fat density lesion [Figure 1]a with no 68-gallium DOTANOC uptake in it [Figure 1]b. In lung window settings, no extension in to adjacent lung parenchyma is noted [Figure 1]c with no 68-gallium DOTANOC uptake in it [Figure 1]d.
Figure 1: (a) Axial contrast-enhanced CT in soft tissue window shows a well defined left pleural lesion with fat density, which on fused 68-Gallium DOTANOC PET/CT (b) shows no somatostatin receptor expression. (c) In lung window axial CT, there is a lesion seen in the left thoracic cavity, with no extension into the adjacent lung parenchyma. (d) Fused 68-Gallium DOTANOC PET/CT in the lung window shows no somatostatin receptor expression in this lesion
