In T1 weighting after injection gradually increases in volume, sometimes becomes symptomatic and Muscle Strain (2) There are typical chronic changes such as focal tendon thickening (blue arrow) and peritendinous muscle atrophy (yellow arrow). The vastus lateralismuscle is part of the four muscles that make up the quadriceps. muscle with a rim of fat at the superior and inferior poles; B. T1-weighted The four muscles all extend the lower leg. The rectus femoris is a biarticulate muscle, meaning it passes over two joints: the knee and hip. The other muscles involved were variable and included the ipsilateral vastus medialis, vastus lateralis, sartorius, adductors, biceps femoris, semitendinosus, iliopsoas, and tensor In many muscles, the tendon extends deeply into the muscle creating a long musculo-tendinous junction (figure). as a significant liquid T2 hypersignal. David A. On the left a patient who had gone for a run for the first time in quite a while. The rectus femoris is the most superficial of the quadriceps muscles alongside the vastus lateralis, vastus intermedius, and vastus … intramuscular myxoma. The other muscles of the quadriceps include the vastus medialis, the vastus intermedius and the vastus lateralis. Intraoperative findings demonstrated fibrous band of vastus intermedius and vastus lateralis muscles which correlated with the MRI. On the left the same patient. When in doubt use gadolinium to see if the abnormality enhances. The clinical symptomatology was in the majority of cases misleading; A fascial tear is a typical sports injury and most commonly involves the calf (figure). calcifications.

The remaining 3% will show an epimysial strain pattern, with the abnormalities found at the periphery of the muscle. There is an epimysial pattern of edema and sciatic nerve irritation. Seven patients had associated edema in other thigh muscles.

The muscle herniates through the fascial defect, protruding upon muscle contraction. The epimysium is the fibrous tissue that lies at the edge of the muscle. myxoma. undifferentiated stellate cells within a myxoid tissue which gives a This example shows edema with an epimysial pattern which is common around the flexor hallucis. The radiological examination did not give much guidance for the diagnosis. which was confirmed by the initial diagnosis. in relation to the superficial plane fixed to the deep plane, with a hard strongly directs the diagnosis towards intramuscular myxoma. postcontrast coronal MRI showing homogeneous enhancement with hypo There is normal muscle architecture on the T1-weighted image, and increased signal on T2-weighted image and STIR. Outside of EMG, Per Tesch found a difference via MRI. The fiber orientation of the vastus medialis may also compensate for less strength and size compared to the vastus lateralis. Compartment syndrome progresses to rhabdomyolysis if untreated.

In calcific myonecrosis an entire single muscle is replaced by a fusiform mass with central liquefaction and peripheral calcification. females [2]. The Biceps femoris ( Biceps) is situated on the posterior and lateral aspect of the thigh. On T1-weighted image there is a gap in the muscle with a small amount of fat filling it up. Fourteen female volunteers were evaluated, average age of 22 ± 2 years, sedentary, without clinical symptoms, and without history of previous lower limb injuries. In this book, recognized experts from around the world provide a comprehensive overview of the value of cutting-edge MRI for the assessment of normal and diseased skeletal muscle.

The rectus femoris is the most superficial of the quadriceps muscles alongside the vastus lateralis, vastus intermedius, and vastus medialis. Particular emphasis is placed on MRI. The updated edition includes new chapters on soft tissue lymphoma, soft tissue tumors in the pediatric patient and biopsy of soft tissue tumors. depending on the tendon injured. treatment of choice for this type of tumor is broad surgical removal Kinematic MRI techniques were developed because various pathologic conditions are dependent on the specific position of the joint or in response to loading or stress.

On T1-weighted images you will see fat in the muscle in very predictable patterns, with either linear, branching or feathery distributions, depending on the architecture of the muscle.
