Incidental finding of an undifferentiated sarcoma during lower limb Doppler ultrasound: A case report.

Introduction: Undifferentiated sarcoma is considered a rare and aggressive type of soft tissue sarcoma with the lower extremity reported as the common site for soft tissue sarcomas.

Case Presentation: We present a rare incidental finding of undifferentiated sarcoma during lower limb Doppler ultrasound with a presenting symptom of right thrombotic-like calf pain in a 49-year-old female.

Discussion: On ultrasound, the presented undifferentiated sarcoma appeared as a large heterogeneous, oval-shaped, soft tissue mass deeply seated in the right calf with involvement of the soleus muscle.

Peripheral nerve sheath tumour mimicking deep calf thrombus: An incidental finding during lower limb venous Doppler ultrasound.

Introduction: Peripheral nerve sheath tumours are neurogenic neoplasms that arise from the nerve sheath which are not within the central nervous system. While most of these lesions may be benign, some of them may undergo malignant transformation, establishing why it is imperative for ultrasound practitioners to familiarise themselves with ultrasound presentations of this lesion to facilitate early and effective diagnosis, which would in turn positively impact patient management.

Case Report: We present an incidental finding of a thrombus-mimicking peripheral nerve sheath tumour in a female patient who came to the ultrasound department for a left leg deep vein thrombosis scan.
