Hepatic nodular myelolipomatosis (myelolipomas) associated with a peritoneo-pericardial diaphragmatic hernia in a cat.
Multiple hepatic myelolipomas were found in a domestic cat with a concurrent congenital peritoneopericardial diaphragmatic hernia. Histological features of the myelolipomas consisted of unencapsulated nodules composed of adipocytes interspersed with islands of haemopoietic tissue. The myelolipomas probably originated as metaplastic change within the liver, initiated by chronic hypoxia caused by entrapment of the affected liver within the pericardial sac. Nodular myelolipomatosis is suggested as a more accurate term for the non-neoplastic nodules referred to as myelolipomas.
