CT of the elbows, pelvis and stifles –
Right elbow:
An isolated and mildly displaced wedge shaped fragment is seen at the tip of the
medial coronoid process (MCP). The base of the MCP reveals marked sclerosis. There
is a mild radioulnar step formation. The humeroulnar joint space is asymmetric with
mild central widening. The radioulnar incisure is irregular in width with craniad
tapering. The subchondral bone of the humeral trochlea reveals a focus of sclerosis
apposed to the MCP. A subchondral bone defect is not seen. There are mild to
moderate osteophytes emerging from the periarticular margins.
Left elbow:
The MCP presents marked overall sclerosis with irregular outline and focally
decreased attenuation at its tip and towards the radioulnar incisure. An isolated
fragment or fissure is not seen. There is a mild radioulnar step formation. The
humeroulnar joint space is mildly asymmetric. The radioulnar incisure is irregular in
width and tapering cranially. Emerging osteophytes are noted at the periarticular
margins.
Shoulders:
There are no bony lesions noted. The subchondral bone of both humeral heads is even
and smooth.
The assessment of the soft tissues is limited to low signal to noise ratio. The biceps
tendon is seen continuously from its origin at the supraglenoid tubercle and within the
intertubercular groove. The bone surface of the intertubercular groove is even and smooth.
The supra- and infraspinatus tendons are within normal limits regarding their anatomy
and structure.
There is no evidence of a mass lesion within the brachial plexus region. The axillary
lymph node is within normal limits.
