Venous malformations (VMs) are present at birth, grow proportionally during childhood, and usually do not regress. We report the imaging appearance of a VM of the foot found during pregnancy, which regressed spontaneously postpartum. A 35-year-old, 8-month-pregnant woman presented with a 6-month history of painful swelling of the left foot. MRI demonstrated a well-defined, intricate-shaped mass measuring 38 × 36 × 28 mm between the muscles and tendons of the third, fourth, and fifth toes with subcutaneous extension. Dynamic CT taken a month after delivery revealed gradual enhancement of the lesion. Gray-scale ultrasonography (US) showed a heterogenic hypoechoic mass containing thrombi with venous waveforms on Doppler US. A second MRI obtained 15 months after delivery showed a remarkable reduction of the lesion size (16 × 20 × 15 mm). Symptomatic VMs found during pregnancy can be observed conservatively without treatment.

Disease Location
Venous system of the left foot
Personal Characteristics
35-year-old, 8-month-pregnant woman
Clinical Characteristics
Presented with a 6-month history of progressive pain and swelling in the left foot between the fourth and fifth toes. MRI demonstrated a well-defined intricate-shaped mass measuring 38 × 36 × 28 mm between the interosseous muscles and tendons of the third, fourth, and fifth toes with subcutaneous extension. Fine needle aspiration revealed pale blood, indicating a vascular lesion
Remission Characteristics
MRI obtained 15 months after delivery showed a remarkable reduction of the lesion size (16 × 20 × 15 mm
Treatment & Mechanisms
Clinical Treatment
Fine needle aspiration
Non-Clinical Treatment
None reported
