An Interesting Case of Fornix Rupture Discovered Accidentally on Bone Scintigraphy

A 62-year-old male patient, with bladder carcinoma, was referred to our institution for Technetium-99m methylene diphosphonate bone scintigraphy to assess for bone metastasis. While the bone scan showed no abnormal uptake, extraosseous uptake was detected in the left perirenal and pelvic regions on the whole body scan. Computed tomography showed fornix rupture and demonstrated tracer pooling in the perirenal collection. Our diagnosis was very consistent, and oriented the therapeutic attitude towards a percutaneous drainage for the perinephric urinary leak.
