Case: Parsonage-Turner syndrome, also known as brachial neuritis or neuralgic amyotrophy, is characterized by sudden-onset pain and subsequent weakness of the shoulder. Known precipitating factors include viral and bacterial infections and certain immunizations. Isolated cases after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported. We report the case of a 66-year-old woman with right shoulder dysfunction and medial scapular winging after immunization with the SARS-CoV-2 BNT162b2 vaccine (Pfizer). Conclusion: After physical therapy, the patient resumed her normal activities of daily living. Findings from this case represent the first known documentation of Parsonage-Turner syndrome after SARS-CoV-2 BNT162b2 vaccination.

Case: Tibial plateau fractures can be associated with arterial injuries or dysvascular limbs, particularly in settings of trauma. Dysvascular limb in the setting of fracture is commonly due to dissection of the artery. Entrapment of the artery within the fracture is rare. We report a 48-year-old man who presented with left popliteal entrapment within a left tibial plateau fracture status-post external fixation and stent placement in the popliteal artery. Conclusion: Findings from this case highlight entrapment of an artery as a mechanism of a dysvascular limb in the setting of high-energy lower-extremity fractures and specifically for tibial plateau fractures.

Aneurysm of a pulmonary vein is a rare vascular anomaly that is usually discovered incidentally as a pulmonary nodule or mediastinal mass. Most patients do not have any symptoms but some patients can present with dyspnea, hemoptysis, or cerebral thromboembolism. Proper diagnosis is crucial as to avoid unnecessary testing or surgical procedures. We highlight a case of an asymptomatic 59-year-old female with a pulmonary vein aneurysm presenting as a 1.5 cm right infrahilar nodule on contrast-enhanced CT during evaluation for acute cholecystitis. Further investigation with MRA revealed that it was vascular in nature, and pulmonary angiography showed dilation of the right inferior pulmonary vein with no communication to the pulmonary artery. On serial imaging, there has been no change in the size of the aneurysm. A small non-enlarging pulmonary vein aneurysm should be managed expectantly.
