Diffusion tensor imaging (DTI) has been used in veterinary medicine for cerebral infarctions and degenerative diseases in recent years. Defining normal values for the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) to detect lesions is challenging because these values depend on anatomical differences in the spinal cord, magnetic resonance imaging (MRI) machine model, magnetic field strength, and measurement protocol. Shannon entropy is the average amount of information and is a measure of the variability or complexity, of distributed numbers. The purpose of this study is to evaluate whether Shannon entropy can serve as a useful new indicator for interpreting the structural integrity of the canine spinal cord. We used six beagle dogs with no spinal cord disease, as confirmed by neurological examination and magnetic resonance imaging. We calculated the respective values for the cervical and thoracolumbar spinal cord under the 3 T magnetic field. The ADC and FA values (mean ± standard error) of the cervical spinal cord were 1.11 ± 0.05 × 10<sup>−3</sup> mm<sup>2</sup>/s and 0.64 ± 0.02. The thoracolumbar spinal cord had values of 1.16 ± 0.04 × 10<sup>−3</sup> mm<sup>2</sup>/s and 0.58 ± 0.02. The ADC and FA values of the spinal cord reflected anatomical differences, and no fixed normal values were observed for the entire spinal cord. Shannon entropy was 5.67 ± 0.45. No significant differences were observed in the values at any intervertebral level. These results suggest that Shannon entropy is more useful than the ADC and FA values. Shannon entropy may be able to differentiate between normal tissue and lesions, independent of various MRI conditions.

An 11-year-old male French bulldog presented with incidental cystic lesions by the pulmonary CT. CT revealed two cysts in the right caudal lobe of the lung that were suspicious for emphysematous lesions. These cysts were divided into an air layer and a soft tissue-like layer. Dynamic computed tomography (DCT) of cysts revealed undulating motion in the soft tissue-like layer. The dog’s rearing environment included brackish water, and it was evident that the dog had been eating brackish water crabs from the river. The dog was diagnosed with paragonimiasis. This DCT imaging revealed movement of live worms inside the cysts. This study is the first report that DCT may be useful for differentiating paragonimiasis from other pulmonary lesions.

A 5-year-old spayed female domestic short haired cat presented with chronic nasal obstruction. The cat was diagnosed with B-cell nasal lymphoma based on histological examination of biopsy specimens and intracranial invasion was suspected. We initiated treatment with nimustine (ACNU), known to pass the blood–brain barrier, as the primary protocol with prednisolone, with the owner’s consent. The ACNU dose was 20–25 mg/m² (4–5-week intervals, four or six administrations, two courses). The cat remained oligosymptomatic until day 962 after the frst dose and no serious adverse events were reported. The cat lived until day 1089. To our knowledge, this is the frst report of long-term survival achieved using ACNU as the primary treatment in a cat with nasal lymphoma.

A case of hydronephrosis due to intrarenal ureteral obstruction in a Japanese Black calf 査読あり

A 23-day-old Japanese Black female calf presented with distension of the lower abdomen. Abdominal ultrasonography revealed a cystic structure with fluid accumulation and moderate echoluminance in the right abdominal cavity. Ultrasonography and contrast-enhanced computed tomography revealed congenital hydronephrosis due to narrowing of the intrarenal ureter, and right kidney resection was performed. Blood urea nitrogen and serum creatinine levels, which were within reference values preoperatively, peaked on the third postoperative day and gradually decreased afterward until reaching preoperative values on the tenth day. In bovine hydronephrosis, nephrectomy may provide a favorable prognosis if one kidney is intact. Moreover, this case suggests that blood tests immediately after surgery are not suitable for evaluating residual kidneys.

This study investigated the diagnostic and surgical management of urachal abscessation involving the urinary bladder in three cattle aged >18 months. While the abdominal floor or paralumbar fossa are typically considered for accessing the urachus and bladder in calves and heifers, the distance is too great to perform the procedure under direct vision in adult cows. Therefore, a novel preinguinal approach was used for access in cows with urachal abscesses after 18 months. Access was successfully achieved in all the three cows through a preinguinal incision to the urachal abscess at the apex of the bladder. However, in cases wherein the abscess and adhesions are severe, removal may be challenging or may necessitate a combined median or paramedian approach.
