Phosphoglyceride crystal deposition disease requiring differential diagnosis from malignant tumors and confirmed by Raman spectroscopy: A case report

Figure 1 Contrast-enhanced computed tomography shows a 50 mm × 40 mm × 48 mm mass protruding from below the serosa at the greater curvature of the upper stomach. A: Contrast enhancement is observed in the arterial phase; B and H: A 50 mm × 40 mm × 48 mm mass protrudes outward from the greater curvature of the upper stomach; C and I: A nodule about 7 mm in size is found near the accessory spleen; D and J: Three masses protruding from the abdominal wall into the peritoneal cavity are also observed. The most cranial abdominal wall mass measures 28 mm × 16 mm × 18 mm and has irregular margins; E and K: The middle abdominal wall mass measures 55 mm × 42 mm × 36 mm and has irregular margins; F and L: The most caudal abdominal wall mass measures 55 mm × 44 mm × 55 mm and has irregular margins. All of these masses show internal calcification and contrast enhancement; G: Plain computed tomography.
