From: Rare occurrence of metastasis from lung cancer to the anus: case report and review of the literature
Maximum intensity projection (MIP) image of 18F-fluorodeoxyglucose-staging PET/CT showing hypermetabolic left-lung primary and mediastinal/left axillary lymph node involvement (1a). Transaxial superimposed PET/CT images showing no focal pathological uptake at the anus (1b). After four cycles of chemotherapy, the MIP image revealed new involvement of the adrenals, multiple bone metastases, and perianal uptake. Partial metabolic response in the left primary lung tumor (2a). Transaxial superimposed PET/CT images showing intense focal uptake at the left aspect of the anus (2b)
