“…Calcification in tumors usually follows a cellular injury, such as tissue necrosis, inflammation, and hemorrhage (1). Calcification in tumor is commonly seen in association with certain benign and malignant tumors (9). In treatment-naive malignant tumors, calcifications are often associated with internal necrosis or high mucus content, the former indicative of poor differentiation of tumor cells (9).…”

“…However, tissue damage due to inflammation can also cause calcification. In humans, sclerosing mesenteritis has also been identified as a calcified mass (9). Tissue damage causes endogenous calcium release from the mitochondrial and endoplasmic reticulum reserves, which is augmented by increased exogenous calcium entry through the damaged cell membrane (1).…”

“…Calcification in the primary intestinal tumor is a very rare finding in both human and veterinary literature (2,5). In humans, the calcified primary tumors in mesentery, peritoneum, retroperitoneum, liver, gallbladder, pancreas, adrenal glands, kidney, urinary bladder, uterus, penis, colon, appendix, and lymph node have been documented (9). In dogs, the calcified primary tumors in the liver, pancreas, adrenal gland, prostate, mammary glands, and ovaries have been documented (5).…”

An eight-year-old, intact female, Shih-Tzu, weighing 4.5 kg presented with complaints of anorexia, pale mucous membrane, and vomiting for the past 5 days. On physical examination, nausea, abdominal pain, and melena were noted. On hematologic examination, severe anemia and thrombocytosis were identified. On radiographs examination, soft tissue opacity with small faint mineral opacity mass in the mid-abdomen and two mineral opacity regions in the cranial aspect of mass were identified. Ultrasonographic findings showed thickening of descending duodenal wall with loss of layering and mineralization within the duodenal wall and mesentery adjacent to the duodenal lesion. Computerized tomography showed circumferential wall thickening of descending duodenum with mineralization. Mineralization of the mesentery and mesenteric lymph nodes was identified. Based on the diagnostic imaging, the tentative diagnosis was descending duodenal tumor with dystrophic mineralization. Endoscopy revealed mucosal hemorrhage and erythema within the descending duodenum and stomach. Surgery was performed, and mineralization in the pancreatic tail to duodenum and mesentery was found. Resection of the duodenum, regional lymph node, and mineralized pancreatic region and the duodenal anastomosis were performed. The histologic examination revealed a high-grade undifferentiated duodenal carcinoma with metastases to the regional lymph node and mesentery. The patient was managed with supportive therapy for 8 days and discharged. The patient was followed up for 5 months and there were no complications.

“…The morphology that can be visualized on conventional radiology is calcification in the form of popcorn-like. (Zulfiqar, 2020) Figure 2. Plain abdominal radiograph shows a groundglass appereance with extension from the pelvic cavity to the abdomen with a superior displacement of bowel gas shadows (Hanifa, W., 1999).…”
