Splenomegaly is a criterion of hypersplenism; The size of the spleen correlates with the degree of anemia. Yetter, Ellen M., et al. Repeat measurements indicated that spleen length (median difference, 0.10 cm; range, 1.8 to 1.7 cm) and volume (median difference, 3 cm 3; range, 106 to 142 cm 3) were quite stable. Therefore, spleen size assessments from ultrasound imaging are commonly performed in SCD clinics, and typically involve measuring the length of the spleen. References: 1. CT scans may be used to determine the size of the enlarged spleen. Enlargement of the spleen is an important criterion in diagnosing primary myeloproliferative diseases.1-3Because splenomegaly may occur in patients in whom the spleen is not palpable, the most sensitive imaging procedure for measuring splenic size has been sought. ; In some cases, removing the spleen is part of the treatment, but it can make the person much more susceptible to infections.
