“…These are benign tumours, but due to their large size may compress adjacent organs, e.g., causing hydronephrosis. Retroperitoneal lipomas of considerably sizes (several kg) have been reported in children, where the main clinical sign has been an enlarged abdomen of long duration [ 15 ]. As in humans, perirenal lipomas should be considered in calves with distended abdomen, even in cases without other signs of tumours.…”

Congenital infiltrative lipomas and retroperitoneal perirenal lipomas in a calf

BackgroundCongenital lipocytic tumours have rarely been reported in cattle. Lipomas are benign tumours, but infiltrative lipomas have significant health implications due to their aggressive infiltrative growth pattern.Case presentationA calf was born with skeletal malformations and soft tissue proliferations, primarily on the external thoracic wall. The calf was euthanized for welfare reasons and submitted for post mortem examination. Necropsy, histopathology and post mortem computed tomography scanning revealed two types of lipocytic tumours. Widespread infiltrative lipomas were present in the muscles and connective tissues along the vertebral column and diffusely invaded the external soft tissues of the right thoracic wall. The neoplastic lipocytes had invaded intervertebral spaces thus causing congenital vertebral malformations, and further invaded the vertebral canal and the bone marrow of coccygeal vertebrae. Periosteal localization of the tumour was associated with costal hyperostosis. Two large retroperitoneal lipomas enclosed the kidneys and occupied much of the abdominal space.ConclusionThe development of congenital bone malformation in this calf illustrates the severe consequences of the infiltrative and aggressive growth of infiltrative lipomas during foetal development. The congenital retroperitoneal lipomas occupied a large part of abdominal cavity, but did not invade the adjacent tissues. Due to their large size, perirenal lipomas should be considered in calves with distended abdomen, even in cases without other signs of tumours.

“…[3] In a series of 190 retroperitoneal tumors in infants and children only two were lipomata. [4] Till 1979, only 12 cases of retroperitoneal lipoma in children, diagnosed in the first decade of life, were reported in the literature. [45]…”

“…Two cases of histologically proven giant retroperitoneal lipomas, evaluated by CT and sonography, appear to be similar on CT, but they exhibit different echographic patterns sonographically. [7] Weather the lipoma is congenital in infants is uncertain, as abdominal masses are not seen at birth in most cases,[4] but the presence of a huge abdominal mass in early infancy, in this patient, indicates that this retroperitoneal lipoma is most probably congenital. The lipoma may be too small at birth to be recognized.…”

“…Differential diagnosis includes a wide range of possible pathological origins although 90% are Wilms tumors or neuroblastomas. [1][2][3] Most of the remaining retroperitoneal masses, such as in multicystic kidney, hydronephrosis, or adrenal hemorrhage, can be excluded by ultrasonographic scanning. 1 Retroperitoneal lipomatous tumors are very rare in children.…”

6-MONTH-OLD BOY was referred to our hospital for evaluation of a left upper quadrant abdominal mass. The infant was born of an uneventful pregnancy. Findings from several routine checkups after birth were normal. A few days before admission to the hospital, the mass, detected during a routine physical examination, was thought to be splenomegaly. There was no history of abdominal pain or fever. Physical examination disclosed an egg-sized, clearly definable, smooth, nontender mass in the left upper quadrant of the abdomen. The mass was unmovable. Imaging procedures included an ultrasonographic
