The accessory navicular bone, of which three variants have been described, is often considered as a normal anatomic and roentgenographic variant. Is a congenital anomaly in which the tuberosity of the navicular bone develops from a secondary ossification center and it has an incidence estimated between 2% and 14% with higher incidence in women being bilateral in 50-90% of the cases. Our aim was to report a case and review the literature about this uncommon lesion. We carried out a review of medical records, photographic record of diagnostic method, and review from the literature. A 59 years old woman with pain in the medial side of the left foot for two years. Refers worsening with walking. Physical examination with specific ankle negative tests, without bruise or edema. Denies torsion, trauma and surgeries. Magnetic resonance imaging demonstrates type II accessory navicular bone with edema and navicular bone edema. These findings with clinical complaint are compatible with accessory navicular bone syndrome. This report demonstrates the difficulty of diagnosing this lesion, since its physical examination is non-specific, and it can simulate more complex pathologies, requiring complementary tests for its correct diagnosis.Downloads
