Abstract:
18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) with computed tomography (CT) has become the standard of care in staging, restaging, and response assessment of various malignancies including malignant melanoma. However, nonspecific uptake of FDG can occur in infectious and inflammatory conditions and can mimic a tumor. We present here a case of gossypiboma of the axillary region with FDG uptake detected in a patient with malignant melanoma of the upper extremity and discuss the potential pitfalls of this entity on FDG-PET/CT.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
