A pаtient is referred fоr аn аbdоminal ultrasоund after a CT demonstrated a possible mass near the gallbladder. The ultrasound demonstrates mild hepatomegaly with an overall increase in echogenicity. The area in question appears hypoechoic to the surrounding tissues. What is most likely demonstrated on the ultrasound?

Antоniо Mаlаquiаs Hоffnagle was well into his 6th month of age when he was hospitalized for pneumonia. In the following year he was hospitalized five times for additional episodes of pneumonia, septic arthritis, and febrile convulsion. Yesterday, Antonio was diagnosed with pneumonia caused by Pneumocystis jirovecii, and consultation with an immunologist was requested. Antonio’s tests revealed neutropenia, normal numbers of B cells and T cells, and slightly elevated IgM, but a marked decrease in IgG and IgA compared with normal. Autoantibodies against neutrophils were not detected. Liver function tests were normal. Bone marrow aspiration indicated severe maturational arrest of the myeloid lineage at the promyelocyte–myelocyte stage. A diagnosis of X-linked hyper-IgM syndrome (XHIGM) was made. Antonio’s parents were informed that their son would require long-term treatment with intravenous immunoglobulin (IVIG), prophylactic antibiotics, and periodic injection of granulocyte colony-stimulating factor (G-CSF) for episodes of neutropenia. What T cell-produced cytokine that helps with affinity maturation and isotype switching is likely mutated that would lead to these conditions?
