Region Ultrasonography Nuclear Nuclear magnetic resonance
Right thigh Subcutaneous infiltrative edema in the distal third. Presence of collection/abscess in third distal of anterior and medial thigh, measuring respectively 4.2 × 0.8 cm and 4.0 × 1.8 cm. Collection involving vast intermediate and lateral 3.8 × 0.8 cm in axial axes presenting wide margin and contour with femoral cortical but without signs of periosteal reaction. No joint effusion.
Right knee Lateral compartment presenting at least two hypoechoic collections, measuring 2.7 × 0.4 cm and the other (super - lateral) measuring about 1.3 × 0.8 cm. Venous Doppler: Absence of images compatible with deep or superficial thrombosis in the lower right limb. Collections with partially defined limits with intramuscular component in the distal aspect of the vast intermediate 4.2 × 1.8 × 0.9 cm with apparent communication with the joint capsule and extension for subcutaneous planes.
Right upper limb Subcutaneous infiltrative edema in the elbow region and posterior face of the forearm. Large abscess in the olecranon fossa. Right Elbow

Poorly defined collections of inflammatory aspects with hyposignal T1 and hypersignal T2, located in myoadiposal planes, involving the biceps and triceps brachii muscles, the largest one measuring 7.4 × 3.6 × 1 cm with intense contrast enhancement.

Left thigh Subcutaneous infiltrative edema. Inflammatory/infectious appearance collections in myoadiposal planes exhibiting intense post-contrast parietal enhancement:

    - Vast lateral and intermediate: Measuring 4.5 × 2.1 cm with intramuscular extension.

    - Medial and rectus femoris: Two juxtaposed and confluent collections measuring 2.8 × 0.8 cm.

Left hip Important edematous/inflammatory subcutaneous infiltrate, without significant collection. Inflammatory/infectious appearance collections in myoadiposal planes exhibiting intense post-contrast parietal enhancement:

    - Maximum and average gluteus measuring 8.9 × 7.7 × 3.7 cm (13 ml).

    - Adductor magno 5 × 1.7 × 1.6 cm (7 ml).

Left leg Subcutaneous infiltrative edema in the posterior face of the leg. Distal third of the medial gastrocnemius presenting collection/abscess measuring around 4.1 × 1.2 cm. Inflammatory/infectious appearance collections in myoadiposal planes exhibiting intense post-contrast parietal enhancement.

    - Soleus: Two small collections poorly defined 0.5 × 0.3 cm and 0.6 × 0.5 cm.

    - Tibial anterior: 1.1 × 0.4 cm.

Left upper limb Subcutaneous infiltrative edema in the elbow region and anteromedial face of the forearm. Left elbow

Net collection of well-defined margins, located at the transition between the subcutaneous planes and the pronator round muscle, measuring 2.8 × 2.3 × 0.9 cm showing peripheral enhancement after contrast infusion.

Transthoracic echocardiography Within the normality. Unrealized.
