Here is a case of an 8-year-old female neutered Golden Retriever with periods of lethargy and inappetance. What are your findings? This case is subtle. Make sure to search the periphery of the radiograph…
THORAX: The cardiovascular structures are within normal limits. There are multiple rib fractures involving the left 4th through 9th ribs and the right 5th, 6th and 9th – 11th ribs. There are multiple areas of punctate lucencies within the thoracic vertebrae, ribs and humeri.
SURVEY SPINE: Lateral views are available. There are multifocal areas of punctate lucencies throughout the cervical, thoracic and lumbar spine. Lucencies are also identified in the ribs, humeri, ilia wings and femurs.
Multifocal punctate lytic lesions are consistent with round cell neoplasia such as multiple myeloma or plasma cell tumor and multiple pathologic rib fractures. Other differentials include metastatic neoplasia such as carcinoma.
Poorly differentiated plasma cell tumor.
