Laboratory tests showed mildly elevated C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).

Multidetector computed tomography (MDCT) with pulmonary thromboembolism (PTE) protocol excluded PTE but incidentally identified RVOT aneurysm. Conservative management with aspirin and colchicine led to symptom resolution; at 6-month follow-up, the patient was asymptomatic with stable imaging. This incidental finding underscores MDCT’s utility in detecting coexisting structural anomalies in patients presenting with pericarditis. Conservative management is appropriate for asymptomatic cases without obstruction.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"21 4","pages":"Pages 1622-1625"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146079156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a case of a patient with a bilobed traumatic popliteal artery pseudoaneurysm after knee replacement surgery, treated with popliteal artery stenting. A 75-year-old patient presented 12 days post left total knee replacement with left leg pain and swelling. A duplex ultrasound scan performed demonstrated a popliteal vein occlusive thrombus and a 2.6cm aneurysm of the left popliteal artery. Due to worsening pain and leg swelling, a CT angiogram scan was performed which demonstrated a large bilobed pseudoaneurysm of the popliteal artery. This necessitated emergent treatment and percutaneous popliteal artery stenting was performed. Initial angiography demonstrated extravasation of contrast into a pseudo aneurysm sac, and this was treated with a 6mm x 100mm self-expanding covered stent-graft (Gore Viabahn<sup>TM</sup>).

Computed tomography pulmonary angiography (CTPA) revealed a large saddle embolus at the main pulmonary artery bifurcation with bilateral extension, accompanied by right ventricular dysfunction on echocardiography. The constellation of imaging findings—massive central thrombus burden, right heart dysfunction indices (RV/LV ratio 1.3, TAPSE 13mm), and absence of deep venous thrombosis—prompted consideration of an underlying thrombophilic disorder. Subsequent workup confirmed CAPS with multiorgan involvement. Following treatment with thrombolysis, corticosteroids, and plasmapheresis, follow-up CTPA at three months demonstrated complete thrombus resolution with normalization of cardiac parameters. This case illustrates the characteristic imaging appearance of CAPS-related massive pulmonary embolism and emphasizes the need to recognize high-risk features that suggest underlying systemic thrombophilia.

While the term “polyarthritis” still applies, we have found the name to be somewhat misleading as typical imaging features of inflammatory arthritis are not the predominant findings.

Computed Tomography Angiography (CTA) confirmed the presence of bilateral PSA and revealed a striking asymmetrical presentation. The right limb showed a ``complete'' PSA with a hypoplastic superficial femoral artery (SFA) and an extensive 33-cm intraluminal thrombosis.

This case underscores the necessity of considering uncommon vascular abnormalities, especially their asymmetrical manifestations, in the differential diagnosis of lower limb ischemia.
