Clinical and computed tomography features of secondary renal hyperparathyroidism

Benoît Vanbrugghe et al. Can Vet J. 2011 Feb.

Abstract
in English, French

An atypical case of secondary renal hyperparathyroidism was diagnosed in a 9-year-old miniature schnauzer after a skull computed tomography (CT) showed the presence of 2 bilateral and symmetrical soft tissue maxillary masses, and osteopenia of the skull.

Présentation clinique et tomodensitométrique d’un cas d’hyperparathyroïdie secondaire d’origine rénale. Un cas atypique d’insuffisance rénale secondaire a été diagnostiqué sur un schnauzer miniature de 9 ans après qu’une tomodensitométrie du crâne eut révélé la présence de deux masses maxillaires de tissu mou, symétriques et associées à une ostéopénie diffuse du crâne.

B — Transverse image at the level of maxillary PM4 showing the complete loss of dental alveolar bone around teeth roots (white arrow) giving the “floating teeth” appearance. C and D — Transverse (C) and reformated dorsal (D) images with the 2 fibrous maxillary masses (open white arrowheads) protruding in the nasal cavity and leading to a severe airway obstruction (*).
