F-18 fluorodeoxyglucose positron emission tomography/computed tomography image of gastric mucormycosis mimicking advanced gastric cancer: A case report

Figure 1 Upper gastrointestinal endoscopy images. This reveals a huge ulcer in the posterior wall of the stomach. The ulcer lesion was suspicious for Borrmann type II gastric cancer.

Figure 2 Contrast-enhanced abdominal computed tomography images. A: A huge ulcer lesion with diffuse wall thickening was detected in the posterior wall of the lower body of the stomach (yellow arrow head); B: Multiple enlarged left gastric lymph nodes were noted (yellow arrow).

Figure 3 F-18 fluorodeoxyglucose positron emission tomography/computed tomography images. A: The maximum intensity projection image shows uneven uptake on the stomach (black arrow); B: Axial scan shows increased uptake in the posterior wall of the lower body of the stomach (yellow arrow); C: Several enlarged hypermetabolic lymph nodes were seen at the left gastric chain (yellow arrow head).

Figure 4 Periodic acid-Schiff stain. A, B: Multiple fungal hyphae with positive periodic acid-Schiff staining were observed (black arrow).

Figure 5 Follow-up upper gastrointestinal endoscopy images. A, B: The follow-up endoscopic finding reveals marked improvement of previous mucormycosis lesion.

Figure 6 Follow-up contrast-enhanced abdominal computed tomography images. A: Previous mucormycosis lesion in the posterior wall of the lower body of the stomach showed much-improved state (yellow arrow head); B: Only small left gastric lymph nodes was observed (yellow arrow).
