A 3-year-old, intact female Pomeranian presented with a 1-month history of coughing. Thoracic radiography showed focal infiltration of the left cranial lung lobe and widening of the cranial mediastinum. Subsequent computed tomography revealed torsion of the caudal segment of the left cranial lung lobe, which was confirmed by exploratory thoracotomy. There was no apparent underlying etiology for the condition. To the authors’ knowledge, this is the first report of lung lobe torsion in this breed and the first detailed CT imaging report for segmental lung lobe torsion.

A 10-year-old castrated Shih-Tzu male dog was referred for examination of acute right exophthalmos, protrusion of the third eyelid and soft tissue swelling ventral to the globe. Ultrasonography revealed echogenic fluid around the right globe. Computed tomography (CT) showed an enlarged right zygomatic salivary gland compared with the left zygomatic gland and an amorphous cystic mass ventral to the right globe. Hyperattenuated material, which we suspected to be a sialolith, was identified in the right zygomatic gland. The zygomatic gland and the cystic lesion were removed, and a zygomatic sialocele with sialolith and ductal obstruction were found by histopathological examination. CT was a useful diagnostic tool for zygomatic sialolithiasis.

A 13-year old intact female poodle showed persistent signs of estrus. Ultrasonographically, a large cystic mass containing echogenic fluid with a thin wall was observed, and it was 8 cm in diameter. The cystic mass was located at the mesovarium between the left ovary and uterine horn, and it was identified as a giant parovarian cyst. A right ovarian mass was histologically diagnosed as a granulosa cell tumor. Persistent estrogen hormone secretion by the granulosa cell tumor was thought to cause a rapid increase in the size of the parovarian cyst. This rare cystic mass originated from the genital system and was differentiated from the uterus.

A 14-year-old, mixed breed dog was presented with acute pain and paresis of the hindlimbs. Ultrasonography revealed an intraluminal mass and an abrupt halt of blood flow signal in the distal abdominal aorta. The mass had homogeneous hyperechoic echotexture compared with blood flow. Although clinical presentation suggested a thromboembolism and pituitary dependent hyperadrenocorticism was suspected as a predisposing cause based on adrenal function tests and ultrasonography, an aortic chondrosarcoma originating from the distal abdominal aorta was diagnosed with histologic examination. Primary aortic sarcoma is extremely rare, and extraskeletal chondrosarcoma is only reported in 2 cases previously. Aortic neoplasm should be included in differential diagnosis when an intraluminal aortic mass is observed on ultrasonography and acute paresis of hindlimbs is shown.
