Right arm pain, immunocompromised There is diffusely increased signal subcutaneous tissues of the mid to distal humerus. Additionally, there is increased signal of the surrounding musculature, particularly within the distal portion of the triceps. A mild amount of fluid is noted within the elbow joint and the shoulder joint. There is similar increased signal within the musculature of the posterior chest wall including the latissimus dorsi. Within the limits of an unenhanced exam, there is no discrete focal fluid collection within the arm.The marrow signal of the humerus is normal for the patient's age.
Diffuse inflammation within the subcutaneous tissues of the humerus, portions of the underlying musculature specifically the triceps, and within the musculature of the posterior chest wall. No focal fluid collection is identified within the limits of the exam.
