Intra-abdominal Necrotic Lipoma in a Terrier dog

A ten-year-old female unspayed terrier, weighing 13 kg, presented for chronic abdominal distention, urinary incontinence, and pollakiuria suspected of urinary bladder infection. Physical examination revealed abdominal pressure with pain in palpation. Other clinical signs of the vital organs were in the normal range. Hematology and biochemistry and urinalysis were done. Hematological examination, due to neutrophilia, showed increased white blood cell count (27.6 X 109/L). Other hematological parameters were in the normal range. Biochemical parameters including, albumin, total protein, creatinine, globulin, alanine transaminase (ALT) and aspartate aminotransferase (AST), and uric acid were in normal range except alkaline phosphatase (ALP) (160 IU/L) was higher than the normal range. Radiography and ultrasonography revealed an abdominal mass, measuring (100mm X 74mm X 56mm) near the descending colon. Ventrodorsally (VD) abdominal radiography demonstrated an oval soft tissue mass with areas of mineralization, caudal of the abdomen which displaced descending colon left laterally and was adjacent to the left kidney. Exploratory laparotomy was performed to remove the fatty mass. Histopathological examination revealed a necrotic and moderately calcified cystic lipoma.
