A common manifestation of Primary Myelofibrosis is

Explanation:
Primary myelofibrosis disrupts normal marrow function, leading to marrow fibrosis and ineffective hematopoiesis. To compensate, hematopoiesis shifts to outside the bone marrow, especially the spleen, causing marked splenomegaly. This splenic enlargement is a hallmark feature and can produce abdominal fullness, discomfort, and cytopenias from hypersplenism. A decreased or normal spleen would not fit the disease process, and renal enlargement is not a typical manifestation of primary myelofibrosis.
