“…Nomina Anatomica Veterinaria (2017) was used to name the anatomical reference points used in the measurements. Morphometric measurements of points on bones were determined based on the literature 8,9,11–14 and confirmed based on consultation with a veterinary anatomist (O.Y.). To evaluate the reproducibility of the values, each measurement value of the cat's pelvis was measured three times by the same anatomist (O.Y.…”

“…6 In terms of gynecological cases, radiography is an important method used for examination, uterine infections, genital organ tumors, segmental aplasia, pregnancy pathologies, and dystocia. [7][8][9][10] Radiographic examination is critical in the evaluation of maternal pelvic morphology, fetal number, size, position, and general abdominal status. In addition, gas accumulation surrounding the fetal skeleton or in body cavities on radiography, overlapping or collapse of fetal cranial bones, or changes in the spatial relationships between the bones of the axial skeleton are among the possible markers of fetal death.…”

The size of an animal's pelvis can have a substantial impact on the ease or difficulty of giving birth, which can vary depending on the breed. Radiography is a medical imaging technique that is commonly utilized in clinical cases to assess pelvic dimensions. The present retrospective, observational study was designed to evaluate pelvimetric differences in radiographic images of British Shorthair (BS) cats with dystocia and eutocia. Pelvimetric values (linear distance, angle, area, height/width) for ventrodorsal and laterolateral radiographic images were recorded in 15 BS cats with dystocia and 15 BS cats with eutocia. Statistical analysis of the obtained measurement values was performed. When the pelvimetric data were examined overall, it was seen that mean values, except the PL (pelvis length) measurement, were higher in cats with eutocia than in cats with dystocia. Vertical diameter, conjugate vera, coxal tuberosities, transversal diameter, acetabula, pelvic inclination, ischiatic arch, pelvis inlet area (PIA), and pelvic outlet area (POA) values were significantly higher in cats with eutocia than in cats with dystocia (P < 0.05). Mean PIA and POA measurement values in cats with dystocia were 22.89 ± 2.38 cm2 and 19.59 ± 1.90 cm2, respectively; in cats with eutocia, the mean was calculated as 27.16 ± 2.76 cm2 and 23.18 ± 1.88 cm2, respectively. In conclusion, the present study revealed that pelvimetric values, except the PL measurement, were higher in cats with eutocia than in cats with dystocia. Findings can be used to assist veterinarians in future clinical decision‐making for pregnant BS cats.

“…[6][7][8] Traditional radiography diagnoses apparent sclerosis, which can result from increased bone mineral density (BMD), superimposition of osteophytes or superimposition of soft tissue mineralisation. 9,10 Computed tomography allows multiplanar cross-sectional visualization of the skeletal components of the elbow joint, and allows assessment of true sclerosis without superimposition of osteophytes or soft tissue mineralisation. 11 While sclerosis is considered a sensitive indicator of MCPD in radiographic studies, its clinical significance is not determined, 7 and it is largely a subjective interpretation.…”

Objective The aim of this study was to determine if variations in Hounsfield units (HU) are present within the elbow between asymptomatic dogs of two breeds of dogs susceptible to elbow dysplasia. Study Design Guide Dogs and Border Collies that presented for routine computed tomography (CT) screening for elbow dysplasia prior to breeding were evaluated. All dogs had no documented history of lameness. Dogs diagnosed with CT as being free of elbow dysplasia were included. The CT images were randomized and assessed by three blinded observers. A standardised approach to CT image reconstruction to create consistent image planes was used. Hounsfield units were measured within a standardised region of interest (ROI) at the humeral trochlea and medial coronoid process. The minimum, mean and maximum HU within each ROI was recorded. Results Eighty-six elbows were included in the study with 32 Guide Dogs, and 11 Border Collies. Guide Dogs had significantly higher minimum (99.75 HU, 95% confidence interval [CI]: 15.02–184.48, p = 0.022), mean (115.09 HU, 95% CI: 80.53–149.64, p < 0.01) and maximum (74.00 HU, 95% CI: 44.58–103.42, p < 0.01) difference in HU within the medial coronoid process ROI, and significantly higher mean (146.49 HU, 95% CI: 100.12–192.87, p < 0.01) and maximum (147.77 HU, 95% CI: 102.57–192.97, p < 0.01) difference in HU within the humeral trochlea ROI. Conclusion In this dataset breed variations in elbow HU were present between asymptomatic Guide Dogs and Border Collies. This needs to be considered in breeding screening programmes to avoid over-interpretation of elbow sclerosis, in the absence of elbow pathology.

Pharyngeal dermoid cyst causing partial upper airway obstruction in a cat

Case summary A 2-year-old cat was presented with nasopharyngeal stridor and stertor. Radiographs of the upper neck region showed a mass lesion in the nasopharynx. A nasopharyngeal polyp was suspected, but an attempt at endoscopic removal failed, owing to fragmentation of the mass and excessive haemorrhage. A sample was taken and histology confirmed a dermoid cyst. CT was performed and the lesion was described as most likely to be a dermoid cyst, consistent with the histopathological findings. Surgical exploration and subsequent complete removal of the mass led to a full recovery. Relevance and novel information The nasopharyngeal location represents a previously unreported location of a dermoid cyst. This report raises awareness of dermoid cysts as a potential differential diagnosis within the nasopharyngeal region and highlights the importance of pre-interventional diagnostic imaging.
