Lower leg mass in pulmonary embolism: a case of popliteal vein aneurysm.

Popliteal vein aneurysms (PVAs) are rare entities, with less than 300 hundred cases reported in the global literature. Despite their rarity, they have immense consequences, having the potential to lead to life-threatening conditions such as pulmonary embolisms and even death. Hence, it is vital for clinicians to be aware of this condition. In this paper, we report a case of PVA and its imaging features seen on the varying imaging modalities. Diagnosis often may not be straightforward as it can mimic other non-vascular or soft tissue masses, hence understanding and appreciating its specific imaging appearances is essential. Generally, PVAs are treated surgically with good outcomes with no reported mortality or recurrence of pulmonary embolism.

Letter to the editor: Comment on a case report of thermal injury to spinal cord, a rare complication of percutaneous microwave spine tumour ablation.

Microwave ablation of the spine is an effective treatment option for patients with symptomatic osseous metastases. It is an increasingly common procedure in clinical practice and can be performed in conjunction with other procedures such as vertebroplasty and nerve root blocks. Multiple studies have demonstrated the safety and efficacy of the percutaneous ablation; however potential complications can arise. Thermal injury to the spinal cord is a rare but serious known complication which has severe consequences to the patient. Multiple strategies can be adopted to reduce the rate of complications. We aim to discuss the various technical considerations when performing percutaneous ablation of spinal tumours to decrease the risks of complications.
