Key result
Persistent left superior vena cava was incidentally detected in two patients aged 60 and 62 years during imaging for other indications.
Case Report (n=2)
Persistent left superior vena cava is a rare, benign congenital malformation that is typically asymptomatic and discovered incidentally on imaging.
Awareness of this benign variant prevents imaging misinterpretation; case reports leave open questions on prevalence and clinical relevance.
The persistence of the left superior vena cava is a rare and benign congenital malformation. This malformation is usually asymptomatic and is detected incidentally by imaging exams performed for other causes. We report two cases of persistence of the left superior vena cava, the first in a 62-year-old patient admitted for chronic renal failure for whom a thoracic radiograph after venous catheterization objectified this malformation; and the second in a 60-year-old patient for whom we performed a CT scan with contrast agent which objectified a double superior vena cava.

Adnor et al. (2024) conducted a case report in Persistent left superior vena cava (n=2). Imaging exams (thoracic radiograph, CT scan) was evaluated on Incidental detection of persistent left superior vena cava. Persistent left superior vena cava was incidentally detected in two patients aged 60 and 62 years during imaging for other indications.
