Write answer in between .Q:A 4-month-old male infant is brought in because he rejects food and is losing weight. He had several upper respiratory tract infections during the last 2 months. Upon examination, hepatosplenomegaly is noted, as well as mild hypotonia. During the next few weeks, hepatosplenomegaly progresses, the boy fails to thrive, and he continues to reject food. He has a blood pressure of 10070 mm Hg and heart rate of 84min. Blood tests show pancytopenia and elevated levels of transaminases. Slit lamp examination shows bilateral cherry-red spots on the macula. Chest X-ray shows a reticulonodular pattern and calcified nodules. Biopsy of the liver shows foamy histiocytes. What is the most likely diagnosis?? A: Crigler-Najjar syndrome type I, B: Niemann-Pick disease type A, C: Gaucher disease, D: Primary biliary cirrhosis, E: Gilbert syndrome,  <response>: Based on the clinical presentation of hepatosplenomegaly, failure to thrive, pancytopenia, elevated transaminases, cherry-red spots, and foamy histiocytes on liver biopsy, the most likely diagnosis is a lysosomal storage disease. Niemann-Pick disease type A is characterized by accumulation of sphingomyelin in cells due to acid sphingomyelinase deficiency, leading to hepatosplenomegaly, failure to thrive, cherry-red spots, and foamy cells in bone marrow and other tissues. The other options do not fit the clinical presentation as well.B: Niemann-Pick disease type A
