Summary
A splenic pseudotumor case was analyzed, presenting a cystic and highly vascular solid portion on CT scans. Technetium-99m Sn colloid scintigraphy confirmed the diagnosis, differentiating it from lymphoma or metastatic tumors.
Area of Science:
- Radiology
- Nuclear Medicine
- Pathology
Background:
- Splenic masses require accurate differentiation due to diverse etiologies.
- Distinguishing benign splenic pseudotumors from malignant neoplasms is clinically significant.
Observation:
- A splenic mass with a cystic component and significantly increased vascularity in the solid portion was identified on dynamic computed tomography (CT).
- The imaging characteristics raised suspicion for accessory spleen, malignant lymphoma, or metastatic tumor.
Findings:
- Dynamic CT revealed a splenic mass with heterogeneous enhancement and high vascularity.
- Technetium-99m tin colloid scintigraphy was crucial in establishing the definitive diagnosis.
Implications:
- Accurate diagnosis of splenic masses impacts patient management and prognosis.
- Nuclear medicine techniques like scintigraphy offer valuable diagnostic adjuncts in complex cases.
- This case highlights the utility of scintigraphy in differentiating splenic lesions.
