Probe position 4, 5a, and 5b. (a) Spleen (S) and left kidney (K) are visible; there is no echo-free fluid above or below the spleen. (b) An anechoic fluid collection is visible above the spleen representing pleural effusion (open arrow) on the left side. (c) An anechoic fluid collection is visible around the lower pole of the spleen (open arrow). Free abdominal fluid can be diagnosed. (d) Hypoechoic lesions can be seen inside the spleen (filled arrow). Micro-abscesses due to disseminated TB are a probable explanation.
