The primary difference between splenomegaly and massive splenomegaly lies in the degree of spleen enlargement.
| Feature | Splenomegaly | Massive Splenomegaly |
|---|---|---|
| Spleen Weight | 400-500 g | More than 1000 g |
| Largest Dimension (Poulin et al.) | 11-20 cm (moderate) | Greater than 20 cm (severe) |
| Definition | Enlargement of the spleen | Significant/Severe enlargement of the spleen |
As illustrated in the table, splenomegaly indicates a general enlargement of the spleen, where the spleen weight ranges from 400-500g, or the largest dimension is 11-20cm according to Poulin et al. In contrast, massive splenomegaly signifies a much more pronounced enlargement, with the spleen weighing over 1000g or having a largest dimension greater than 20cm as defined by Poulin et al.
