Tennis Leg- MRI

Increased signal and fluid in relation to the medial head of gastrocnemius muscle with fluid deep to muscle belly between gastrocnemius and soleus. There is proximal retraction of muscle belly along with fluid signal in the myotendinous junction suggesting tear of the medial gastrocnemius.

 MRI findings of tennis leg include: 
1) high T2 signal fluid deep to medial gastrocnemius and superficial to the soleu
2) focal area of disruption of muscle continuity noted along the deep aspect of the medial head of the gastrocnemius, with associated oedema of the muscle






Heel Fat Pad Syndrome

Patient with heel pain shows: Altered signal in the heel fat pad with hypointense signal on T1 weighted images and hyperintense on STIR images. These findings likely heel fat pad syndrome or inflammation.

Slipped Upper Femoral Epiphysis-MRI

14 yr old boy with history of trauma presents with limp and MRI shows slipped capital femoral epiphysis (posteriorly) with diffuse ill-defined marrow edema and cranial migration of the distal fragment with femoracetabular alignment maintained.

 Teaching points by Dr MGK Murthy, Mr Hari Om, Mr Charles

1.    Most common adolescence age group abnormality of hip joint and primary cause of early OA. Usually misdiagnosed early on, more in boys than girls.  It can be spontaneous or traumatic.
2.    Xray particularly AP Pelvis and Lateral frog-leg   views show slip better. Widening of physis , demineralization and Metaphyseal blanch(blush) sign (opacity on X-ray)  are present 
3.    SUFE(Slipped Upper Femoral Epiphysis) grading is made on AP and true lateral  Projections .
4.    On AP Line along the superior margin of femoral neck (kleins)should intersect the lateral corner of Epiphysis. In SUFE, Metaphysis divides in to thirds (mild=lateral edge of epiphysis within the lateral 1/3 of metaphysis) (moderate=Middle third) (Severe= Medial Third)
5.    On True lateral Xray, angle at which epiphysis makes with Metaphysis (Southwick head-shaft angle) (normal = 0 deg, mild=0-30 Deg,moderate30-60 deg, Severe=>60 deg)

6.    CT is useful for measuring degree of tilt. USG has not been usually advocated though can suggest with fluid presence. MRI  shows slip earliest. MRI also  helps in follow up  and also to keep a check on contralateral hip.

Biceps Femoris Tear-MRI

Hamstring tears are among the most commonly encountered injuries in athletes. The hamstrings are comprised of the semimembranosus, semitendinosus, and the biceps femoris muscles. The biceps femoris and semitendinosus arise from a common tendon along the posteromedial aspect of the ischial tuberosity.
