Thin rim of fluid was noted in calf and mid third of leg in subcutaneous plane. Collapsed cyst in calf passes to deeper aspect towards joint.

Case Discussion

One month back ultrasound of the lower limb arterial tree was done which revealed a popliteal cyst of 23 x 18 x 10 mm size. Hence, a ruptured popliteal cyst was diagnosed. Deep venous thrombosis was ruled out, which is the primary differential for this.
