As part of our campaign to #imagemorehorses, we present a case with an initially straightforward and common presentation whereby magnetic resonance imaging became a vital diagnostic tool and essential to the clinical decision-making process. <\/p>\n\n\n\n

History<\/h2>\n\n\n\n

A 9-year-old broodmare was MRI\u2019d due to a persistently draining solar abscess from her right hind foot which, after 3 weeks of routine abscess management, was not improving.<\/p>\n\n\n\n

Case 1 – MRI Findings<\/h2>\n\n\n\n

As expected, STIR and T2 FSE<\/em> images revealed a hypointense pocket in the solar dermis (white arrow) surrounded by a halo of signal hyperintensity (white arrowheads) indicating the region of\u202f subsolar haemorrhage and infection. The location of this pocket and halo, the focal point of infection, was shown to be within the soft tissue at the plantar border of the most distal aspect of the deep digital flexor tendon. The signal intensity within the tendon, fortunately, appeared normal.\u202f<\/p>\n\n\n\n

On the same images, draining material was shown to be exiting close to the lateral sulcus of the frog (red arrowheads). The solar dermis was diffusely hyperintense and thick (green arrows), again consistent with diffuse inflammation and subsolar infection.<\/p>\n\n\n\n

The above left-handed STIR<\/em> image shows a diffuse fluid signal in the lateral palmar process of the distal phalanx,\u202f extending to the body of the phalanx (orange arrow). Which may indicate inflammation or infection within the phalanx.<\/p>\n\n\n\n

The deep digital flexor tendon was of normal appearance on all sequences. <\/p>\n\n\n\n

The navicular bursa was moderately distended but otherwise of normal appearance.<\/p>\n\n\n\n
