Odematous area of proximal belly of soleus muscle, distal belly of popliteus muscle is noted with adjacent soft tissue hypoechogenesity and hypervascularity. No collection is noted.

No obvious erosion of adjacent tibial cortex is noted.

Reative (non-necrotic and ovoid) popliteal nodes are seen in popliteal fossa. Five in number.

Case Discussion

Local infectious/inflammation involving soleus, popliteus muscles and adjacent soft tissue was suggest on ultrasound without collection (no abscess formation) without tibial cortical erosion.

MR done to look for marrow signal abnormality in tibia; which was normal. Rim of subperiosteal fluid was noted.

Popliteal lymphadenopathy can be due to infection (as in this case and case nº 13658), melanoma  (case nº 25965) or due to various other causes.
