Axial T1-WI at the level of the subtalar joint a and slightly below b. The aim of this article is to give a comprehensive overview of the most common pseudotumoural lesions of the foot and their respective imaging features. Adventitious bursitis Adventitious bursae may develop in adulthood at sites where subcutaneous tissue is exposed to high pressure and friction [ 19 ]. Post-traumatic bone abnormalities such as stress reactions and fractures may mimic a tumoural lesion of the ankle or foot. SGA can present a diagnostic challenge, especially when the physician is unfamiliar with this clinical entity. Enhancement after IV gadolinium contrast medium administration is variable [ 66 ].

    Subcutaneous granuloma annulare MR imaging and literature review.

    A 5-year-old female patient with rapidly growing, painless, multiple subcutaneous nodules, on both pretibial areas, was admitted to our.
    Ultrasound shows a hypoechogenic structure with a typical striated appearance of muscle.

    Multiple erosions were seen at the metatarsophalangeal joints not shown. Subtle peripheral enhancement is seen following intravenous administration of gadolinium contrast medium [ 18 ].

    This is just one of the five types of accessory soleus that have been described on the basis of insertion characteristics. The radiological appearance of SGA is characteristic and, combined with the age of the patient and location of the lesion, can suggest the diagnosis.

    There is always communication with the adjacent joint.

    Late-stage lesions display a zonal ossification pattern making diagnosis possible with conventional radiography [ 65 ].

    An abnormal thickening of the tendon sheath with enhancement after intravenous administration of gadolinium contrast medium may be seen. A biopsy was performed which confirmed the diagnosis of subcutaneous granuloma annulare.

    On radiographs, tumoural calcinosis appears as multilobulated calcific deposits in a periarticular distribution, usually along the extensor surfaces of joints.

    On ultrasound examination and MR imaging, plantar fibromatosis typically appears as a poorly defined mass in the deep aponeurosis in the medial aspect of the foot Fig. On ultrasound, SGA appears as an ill-defined hypoechoic nodule without internal vascular flow or cystic lesion.

    Degree and pattern of contrast enhancement are variable [ 34 ]. Patients present clinically with painless, fixed, subcutaneous nodules on the sole of the foot, along the course of the plantar aponeurosis.

    On contrast-enhanced MR images, gouty tophi typically display a moderate to marked heterogeneous or near-homogeneous enhancement [ 47 ].

    Introduction Soft tissue lesions of the foot and ankle are a relatively rare cause of referral for medical imaging. Figure 4 Sagittal T1WI with fat saturation after gadolinium administration.

    There is no typical enhancement pattern on fat-suppressed T1-WI after intravenous administration of gadolinium contrast medium, varying from low to moderate to marked enhancement. Although benign and fairly common in the adult population, it occurs more often and builds up faster on the feet of diabetic patients.

    On ultrasound examination, ganglion and synovial cysts appear as round to oval, monoloculated or multiloculated anechogenic lesions, with posterior acoustic enhancement Fig.

    There is diffuse enhancement of the lesions after gadolinium injection.

    The MR features of ganglion and synovial cysts are those typical of cystic lesions Fig. Excessive fluid accumulation in the tendon sheath can sometimes lead to a mass-like presentation [ 38 ]. SGA will spontaneously regress without treatment and does not require biopsy or diagnostic imaging in clinically apparent cases.

    In the ankle and foot region, they are more frequently associated with symptoms similar to those of lesions at the wrist [ 5 ].
