Enlarged Spleen can mean portal Hypertension. This will enlarge your spleen and will also make your spleen burn up platelets like crazy. Normal platelets is 140-400. With out knowing your Past medical history and your normal blood pressure history. If you have any questions its best to talk with a well known Liver Specialist.
CBC wouldn't necessarily show anything. Treatment would be splenectomy, with or without chemotherapy depending on the final details.
To answer your questions:
1) Without examination, I cannot give an estimate of what the chances are that lymphoma is causing the spleen to be enlarged. However, with the imaging tests you have had done (i.e. CT scans and ultrasounds), this possibility may be less likely.
2) Yes, the CBC (as well as the peripheral smear) is important in the diagnosis of an enlarged spleen. However, there are some diseases that can present with a normal CBC.
3) If it is indeed lymphoma, treatment would depend on the size of the cancer as well as whether it has spread. Without knowing that, it is tough to speculate on the method of treatment.
Followup with your personal physician is essential.
