Adrenohepatic fusion in an alpaca

Adrenohepatic fusion (AHF) is an anomaly of direct parenchymal integration of the liver and adrenal gland with at least a partial absence of an intervening connective tissue septum. In humans, AHF has been documented relatively often; however, in veterinary literature, it has been only reported in non-human primates and ferrets. Here, we describe the histologic features of a case of AHF that was found incidentally in an adult male alpaca ( Vicugna pacos ) that died from gastric impaction.
