RETROACHILLES BURSA BURSITIS MRI ANKLE DISCUSSION ABOUT THE RETROACHILLES BURSA The retroachilles bursa lies between skin and Achilles tendon. It’s not usually seen as its an adventitial bursa caused by chronic friction. It is Uncommonly enlarged. WHERE TO LOOK FOR THE RETROACHILLES BURSA Best seen on axial and sagittal scans. Look posterior to the Achilles,

PERONEUS BREVIS TENDON TEAR MRI DISCUSSION: WHAT'S THE dX Peroneus Brevis Tendon Tear: MRI demonstrates a peroneus brevis tendon tear. There is a longitudinal split resulting in two components of the Peroneus Brevis tendon (Pink arrows). Peroneus Longus (Blue arrow) is normal. WHAT ARE THE FINDINGS There should only be two tendons in the peroneal

SHOULDER SYNOVITIS MRI RHEUMATOID ARTHRITIS DISCUSSION: WHAT'S THE Dx? Extensive synovitis and ACJ erosions from Rheumatoid arthritis. Having synovitis in multiple locations (even if there are no erosions) should raise the possibility of an inflammatory abnormality. Thank you to Dr Joe Thomas (Rheumatologist) for the case. WHAT ARE THE FINDINGS? Image 1: The first image

SPINE MRI INCIDENTAL FINDINGS SPINE MRI INCIDENTAL FINDINGS: WHAT'S THE Dx There is a mass in the deep lobe of the left parotid (We don’t have Histology as yet). The key here is noticing the asymmetry between the left and right (Green arrow) lobes. Even though its obvious and large, it’s still easy to miss

FACET FRACTURE RADIOLOGY CT DISCUSSION FACET FRACTURE CT APPEARANCE The facet is fractured (Pink arrows) but there is no evidence on this image of facet subluxation or dislocation. However the facet joint is widened inferiorly (Green arrow) indicating that the facet capsule must be torn. FACET FRACTURE RADIOLOGY CT: SLIDER TO VIEW IMAGES ARE

SPINE LIGAMENTS MRI INJURY RADIOLOGY TRAUMA INTERSPINOUS WHAT'S THE Dx: INTERSPINOUS LIGAMENT TRAUMA The MRI demonstrates trauma to the interspinous ligament with increased T2FS signal in the region of the interspinous ligament. The interspinous ligament lies between the spinous processes. Oedema indicates trauma to the region but is also a clue to the type of
