As inflammatory polymyositis (PM) is a well-known paraneoplastic syndrome (PNS), screening positron emission tomography-computed tomography (PET-CT) was done at our center which showed focal areas of heterogeneous attenuation and mild diffuse 18F-fluorodeoxyglucose (18F-FDG) tracer uptake in the upper limb muscles and medial, anterior, and lateral compartment muscles of both lower limbs [Figure 1].

In addition to the muscle findings, PET/CT showed a 18F-FDG avid (maximum SUV 11.7) irregular lobulated heterogeneously enhancing mass arising from the dome of urinary bladder with intraluminal polypoid and extraluminal exophytic soft tissue component [Figures 2 and 3].
