Case 1. (a) Appearance of the distal right hindlimb prior to amputation; plantar aspect. (b) Appearance of both hindlimbs immediately prior to amputation. Note the neurogenic muscle atrophy and hindlimb contracture. The orange arrows in (a) and (b) highlight the region of skin necrosis

Areas of necrosis were evident on each hindlimb and both hocks were hyperextended (Figure 1).
CT image of a metastatic lesion (arrow) in the caudomedial musculature of the left hindlimb of case 1. Note the marked atrophy of the hindlimb musculature

The study demonstrated a focal lesion in the caudomedial musculature of the left hindlimb (Figure 2).
Transverse CT slice of the thorax of a cat with suspected multiple pulmonary carcinomas (case 1). Note the pulmonary masses (orange arrows), some of which are wedge-shaped, consistent with tumour emboli causing pulmonary infarcts

Two soft tissue pulmonary masses associated with the right caudal bronchus and extending into the right caudal and accessory lung lobes were also identified (Figure 3).
