Stroke due to Paradoxical Embolization Related to Fibroid Uterus Enlargement Compressing the Right Common Iliac Vein.

Stroke in young women is commonly cryptogenic or associated with an underlying hypercoagulable state (e.g., hormonal contraception). Paradoxical embolization has been postulated as a potential risk factor for stroke in young adults. Many sources of venous thrombosis leading to paradoxical embolization have been described. There have been few reported cases of uterine enlargement leading to iliac vein compression and paradoxical embolization. We present the case of a young adult woman who had a left middle cerebral artery infarction related to patent foramen ovale and right common iliac vein compression from an enlarged fibroid uterus.
