Tendon Involvement in Pedal Infection: MR Analysis of Frequency, Distribution, and Spread of Infection

Abstract

MR evidence of tendon infection is present in approximately half the patients who require surgery for pedal infection. Evidence of spread of the infection along tendons is seen infrequently on MR imaging. Detection of a tendon infection could influence surgical therapy.

“…Peritendinitis was also visible as described previously [5]. In contrast, in cases of tendon and/or peritendinous infection, MRI shows a variety of signals such as circular enhancement of a tendon passing through an area of cellulitis, peritendinous fluid rim, thickening of the tendon diameter and contrast enhancement of the tendon [7].…”

Evaluating Diabetic Foot Infection with Magnetic Resonance Imaging: Kuwait Experience

“…Several investigators [14,23] found MRI to be clearly superior to conventional radiog- raphy and bone scintigraphy, with a sensitivity and specifi city approaching 100% [4][5][6][7][8][9]24] , although some patients with acute fractures, recent surgery and acute neuropathic arthropathy can have juxta-articular marrow signals that mimic those of osteomyelitis [11,25] . In the present study, the sensitivity and specifi city of MRI in diagnosing osteomyelitis were 100 and 63%, respectively, which is comparable to previously reported studies [6,24] .…”

“…MRI imaging criteria used for the diagnosis of osteomyelitis, abscess, cellulitis, tenosynovitis and neuropathic joint were based on those described in previous studies [4][5][6][7][8][9] . Osteomyelitis was diagnosed when focally increased bone marrow signal on FST 2 WI ( fi g. 1 a) and focally decreased marrow signal on T 1 WI with or without cortical destruction, and focal marrow enhancement on postcontrast T 1 WI was observed ( fi g. 1 , 2 ).…”

“…Magnetic resonance imaging (MRI) has been shown to be useful in identifying musculoskeletal pathology, has high accuracy in diagnosing and revealing the extent of musculoskeletal infections [4][5][6][7][8] and frequently dictates the course of treatment. We reviewed foot and ankle MRI images of 29 diabetic patients clinically suspected to have diabetic foot infection in an attempt to evaluate the capability of this technique to depict and characterize the changes present in osteomyelitis, soft tissue infections, deep seated abscesses, tenosynovitis, and neuropathic arthropathy, and to correlate the fi ndings with clinical follow-up and/or histopathology.…”

Magnetic resonance imaging of diabetic foot complications

“…be limited by pre-existing neuroarthropathy, in such cases, MR imaging is mainly used to assess disease extent rather than establish the diagnosis. (41) Post-contrast MR imaging is recommended for the evaluation of soft tissue disease extent. (10) Several imaging features help differentiate neuroarthropathy with superimposed infection from uncomplicated neuroarthropathy.…”
