Summary
Symptomatic splenic hamartomas are rare in children. This case highlights imaging findings and pathology of a large splenic hamartoma in a 14-year-old girl.
Area of Science:
- Pediatric Radiology
- Surgical Pathology
Background:
- Splenic hamartomas are rare pediatric tumors.
- Previous imaging reports are limited, especially MRI.
Observation:
- A 14-year-old girl presented with splenomegaly, pancytopenia, and growth retardation.
- Imaging revealed a large splenic mass with unusual punctate foci.
- Radiocolloid scintigraphy showed reduced uptake in the lesion.
Findings:
- Ultrasound (US) showed punctate foci resembling calcifications.
- Enhanced CT demonstrated a heterogeneous, well-demarcated mass.
- MRI revealed isointensity on T1 and increased intensity on T2 weighting.
- Splenectomy confirmed a red pulp hamartoma with hyalinization and necrosis.
Implications:
- This case expands the understanding of splenic hamartoma imaging characteristics in children.
- The findings suggest that punctate foci on US may represent necrosis/hyalinization.
- Further research into pediatric splenic masses is warranted.
