title: Nutritional secondary hyperparathyroidism in a white lion cub (Panthera leo), with concomitant radiographic double cortical line.
abstract: A captive-bred white lion cub was presented with hindquarter pain, lameness and reluctance to move. Radiographs revealed generalised osteoapenia, multiple fractures, a severely collapsed pelvic girdle, bilateral lateral bowing of the scapulae and mild kyphosis of the caudal vertebrae. A double cortical line, a distinct sign of osteopaenia, was repeatedly seen on the pelvic limbs, most strikingly along both femurs. Based on radiographic findings and a history of an exclusive meat diet since weaning, a diagnosis of nutritional secondary hyperparathyroidism was made. The diet was changed to a commercial kitten food and the cub was given cage rest for 6 weeks. Signs of pain abated and the cub became more active. A guarded prognosis was given for full recovery, as changes to the pelvis were considered potentially irreversible.
