Utility of Bone Marrow Examination in the Diagnosis of Splenomegaly: Experience from a Tertiary Care Center

Introduction: Establishing the diagnosis of splenomegaly is a clinical and pathological conundrum. The present study aimed to evaluate the clinicohematological findings and the significance of bone marrow examination in establishing the etiology of splenomegaly. Materials and Methods: This study was a retrospective analysis of patients with splenomegaly who had indications for bone marrow examination. The study was conducted over a period of 2 years. Detailed hematological and serological investigations were analyzed in those patients. Results: There were 96 males and 60 females. Most of the patients presented with fever. A mild degree of splenomegaly was found in 56.4% of the patients, followed by moderate (39.7%), and massive (3.9%) degree of splenomegaly. Pancytopenia was noted in 15.4% of the patients. Anemia was observed in 96.2% of the cases. Erythroid hyperplasia was the most common bone marrow finding (37.2%). Etiologies of splenomegaly were documented by the clinico-laboratory evaluation in 45.5% of the patients. Bone marrow examination along with peripheral blood examination alone established etiologies in 15.4% of the patients. Conclusion: Anemia and hematological malignancies formed a major part of the etiologies of splenomegaly. Bone marrow examination was an inevitable investigation in these situations. Serological investigations were useful in the diagnosis of nutrition deficiency anemia and infectious etiology. The grade of splenomegaly assessed clinically at the time of presentation provided an important clue for the etiology. Bone marrow examination proved to be an important diagnostic tool in the workup of patients with splenomegaly.
