Zusammenfassung
Bei einer 6 Monate alten, chronisch inappetenten und kümmernden Zwergbartagame (Pogona henrylawsonii) wurde mittels Röntgen und Computertomographie eine hyperdense Herzregion festgestellt. Die pathologische Untersuchung des euthanasierten Tieres ergab als Hauptbefund eine bei Reptilien selten vorkommende hochgradige Nekrose des Myokards mit dystrophischer Verkalkung. Diese wird im Gegensatz zu den häufig beobachteten, meist haltungsbedingten metastatischen Mineralisationen von Weichteilgeweben durch eine primäre Gewebszerstörung verursacht. Als mögliche Auslöser werden infektiöse Prozesse, Mangelzustände, Intoxikationen sowie genetische Komponenten diskutiert. Im vorliegenden Fall konnte die Ätiologie nicht abschließend geklärt werden. Dystrophische Verkalkungen sollten deshalb bei Reptilien mit Mineralisationen von Weichteilgeweben differentialdiagnostisch berücksichtigt werden.
Summary
In a 6-month-old, chronically inappetent Lawsons’s Dragon (Pogona henrylawsonii) with stunted growth a hyperdense cardiac region was found using radiology and computed tomography. At necropsy a profound necrosis of the myocardium with dystrophic calcification was diagnosed. In contrast to the frequently seen metastatic mineralisation of soft tissues, mainly due to poor husbandry, primary tissue destruction is the cause for dystrophic calcification. In reptiles, this is a rarely described form of calcification. Possible causes are infectious processes, nutritional or metabolic insufficiencies, intoxications or genetic components. In the presented case the aetiology could not be determined. In conclusion, dystrophic calcifications should be considered as a differential diagnosis in reptiles with soft tissue mineralisation.
