An Unusual Case of Gastrointestinal Bleeding

الملخص EN

A 10-year-old boy presented with a 3-day history of worsening abdominal pain, fever, emesis and melena.

Abdominal ultrasound revealed a right upper quadrant mass that was confirmed by computed tomography angiogram (CTA), which showed an 8 cm well-defined retroperitoneal vascular mass.

123Iodine metaiodobenzylguanidine (123MIBG) scan indicated uptake only in the abdominal mass.

Subsequent biopsy revealed a paraganglioma that was treated with chemotherapy.

This case represents an unusual presentation of a paraganglioma associated with gastrointestinal (GI) bleeding and highlights the utility of CTA and 123MIBG in evaluation and treatment.
