“…This sign has already been observed in previous human reports, where ultrasonography revealed that intra-mass abnormal vessels had large lumen diameters measuring 1–12 mm ( 14 , 29 , 38 , 43 , 46 ). Arterial supply to PC is acquired via the large abnormal vessels derived from systemic vessels, most commonly including the descending thoracic and abdominal aorta ( 4 , 9 , 13 , 14 , 21 , 27 , 30 ). Unfortunately, despite the origin of blood flow being unknown in the present case, the intra-mass vessels might be derived from the abdominal aorta.…”

“…Unfortunately, the present case had an unfavorable outcome five months after surgery, in which progressive hindlimb paresis developed, resulting in euthanasia. PCs can contribute to the formation of the underlying skeletal deformity when involved subcutaneously ( 16 , 23 , 30 ). Resection of the extremely large, subcutaneous PC mass may be challenging for such bovine cases.…”

“…A protruding, swollen back mass was the common macroscopic characteristic in the previous bovine cases with PCs on their backs (22,23,30). Thus, the macroscopic observation allows easy detection of this disease when supported by palpation (11,12,18,19,22,23).…”

“…Multiple concurrent anomalies such as ectopia cordis, extra-hindlimb, and rudimentary humerus have also been found in a previous calf with a PC mass on its back ( 17 ). Thus, when diagnosing PC, it is necessary to try to detect the associated skeletal deformities, including spina bifida ( 30 ).…”

“…Additionally, the macroscopic and palpation examinations cannot provide pathological findings deeper than the superficial masses, such as the degree of invasion or destruction of the underlying structures and vasculature. In particular, it is very difficult to identify congenital skeletal deformity in such examinations ( 22 , 23 , 30 ).…”

A 4-day-old female Holstein calf presented with a large-sized, protruding mass in its back, at birth. Radiography identified the deformed spinous process in the second and third lumbar vertebras, suggesting spina bifida. Ultrasonography of the back mass revealed anechoic bronchi-like structures and large vessels with rich blood flow running parallel within the homogenous echogenic mass’s parenchyma. Doppler ultrasonography also revealed pulsatile vessels entering into the deeper side of the transverse process of the lumbar vertebras at the right-sided base of the protruding mass. These imaging results were helpful for surgical planning, in which a large arterial vessel was sutured at the right-sided mass’s base, followed by resection of the mass itself. The mass’s resection could be carried out according to the planned surgical procedure, though its invasion was too deep to be resected completely. Histopathology for the resected specimens revealed that the mass mainly had lung-tissue-like structures comprised of bronchi-, bronchiole- and alveoli-like structures, and large vessels, allowing the diagnosis of pulmonary choristoma. Doppler ultrasonography could contribute to the differentiation between the bronchi-like tubular structure and the large arterial vessels on the same images, aiding diagnosis of this disease.
