Splenic hamartoma presenting as an occasional asymptomatic finding

Area of Science:

• Medical imaging
• Pathology
• Surgical oncology

Background:

• Splenic hamartomas are rare benign tumors of the spleen.
• They can be asymptomatic and detected incidentally during imaging studies.
• Accurate diagnosis can be challenging based on imaging alone.

Observation:

• A hypoechoic splenic lesion was identified during screening ultrasonography.
• Computed tomography (CT) and magnetic resonance (MR) imaging were performed for further characterization.
• These advanced imaging modalities were insufficient to establish a definitive diagnosis.

Findings:

• Histologic examination after laparoscopic splenectomy confirmed the diagnosis of splenic hamartoma.
• The lesion's characteristics on imaging did not allow for a conclusive preoperative diagnosis.
• Surgical intervention was required for definitive pathological identification.

Implications:

• Splenectomy may be necessary for the definitive diagnosis of splenic hamartomas.
• This case highlights the limitations of current non-invasive imaging techniques for certain splenic lesions.
• Further research into improved diagnostic methods for splenic hamartomas is warranted.
