An ultrasound with Doppler demonstrated a compressible, heterogeneous lesion with low flow. Laboratory workup was significant for a platelet count of 175,000 (normal 150,000-450,000x109/L), d-dimer of 455 ng/ml (normal <500 ng/ml), and fibrinogen of 250 mg/ml (normal 213-435 mg/ml). The patient was diagnosed with a pure venous malformation, and referred to vascular interventional radiology (VIR) for management.
