Aneurysmal Bone Cyst on the Carpus of an African Collared Dove (Streptopelia roseogrisea)

Abstract

An adult female African collared dove (Streptopelia roseogrisea) was presented for examination of a mass on the medial surface of the left wing. The mass had been present for 2 months but had grown rapidly over the previous 2 weeks. One week after presentation, the mass was surgically excised and the involved alular bone was removed. Results of histologic examination of the mass were consistent with an aneurysmal bone cyst. No underlying factor could be found in this case. The wound healing was uneventful, and no mass recurrence was observed during the following year. To our knowledge, this is the first report of an aneurysmal bone cyst in a columbiform bird.

Multiple occurrences of pathologies suggesting a common and severe bone infection in a population of the Australian Pleistocene giant, Genyornis newtoni (Aves, Dromornithidae)

“…(2004) and Grosset et al . (2012), an aneurysmal bone cyst is also not considered a possible diagnosis for the pathology observed on the tarsometatarsus. Aneurysmal bone cysts are described as expanding osteolytic and cavitary lesions consisting of a central cavity filled primarily with soft tissues and fluids, encapsulated in a thin bony wall (Heatley et al .…”

“…2004; Grosset et al . 2012). Neither descriptions are similar to the dense bone matrix that fills the regions of abnormal bone growth, nor is there as much bone resorption as would be expected should this be the diagnosis.…”

Extraosseous aneurysmal bone cyst in dogs: a report of two cases

“…A few cases of ABC have been reported in dogs (1,18,19,20,22,23,26,27), horses (6,9,13,16,21,28,29), cats (4,5,25,32), bulls (3,12), and birds (7,8). This type of lesion has been reported in the bones of the mandible (3,6,12,13,21), metatarsals (9,16,28), metacarpals (8,29), scapula (4,31), pelvis (18,25), humerus (20,23,26), tibia (22), rib (5), lumbar vertebrae (27), ulna (1), penile bone (19), carpus (7) and skull (8). Due to the infrequent occurrence and variability of the cases, it has not been possible to make predispositions about the species, sex, breed, and age of the patients.…”
