Case — Bladder paraganglioma in a pediatric patient

摘要

A 12-year-old boy presented with a two-day history of gross hematuria and vomiting. Further questioning revealed a one-year history of position-induced paroxysmal headaches, polyuria, polydipsia, nocturia, dehydration, and lethargy. He denied any syncopal episodes, palpitations, night sweats, blurry vision, or anxiety attacks. He was noted to have nor-mal pubertal development. An abdominal ultrasound was performed, and showed an 8.1 x 7.5 cm bladder mass on the posterior bladder wall with hypervascular components (Fig. 1). The patient was brought to the operating theater for cystoscopy, which revealed a large, necrotic mass on the postero-lateral bladder wall. Bladder biopsy was performed. There were significant blood pressure fluctuations during the biopsy. Final pathology reported the mass to be a bladder paraganglioma (PGL).
