Scurvy is a preventable condition caused by a severe vitamin C deficiency for prolonged periods. Most literature cases describe children with neurobehavioral disorders or extreme dietary restrictions. Vitamin C deficiency may be a rare clinical presentation in the developed world; hence, it is often overlooked and can lead to extensive workups when the history alone could have raised suspicion for the diagnosis. We report a previously healthy 29-month-old boy initially admitted to the hospital due to loss of ambulation over a three-week course. The patient had no history of fever, and the inflammatory parameters were normal. Blood workup, plain radiographs, and magnetic resonance imaging (MRI) of the right lower extremity were unremarkable. The patient was discharged home with antibiotics and anti-inflammatory medication but arrived a week later with worsening lower extremity weakness leading to complete loss of ambulation. Vitamin C deficiency was confirmed to be below normal levels (<0.4mg/dL), and a diagnosis of scurvy was confirmed and treated with oral ascorbic acid. Subsequently, his mother brought him to the orthopedic clinic with a positive Gower sign. CPK levels were normal. Within a month of ascorbic acid replacement, all symptoms disappeared. Our patient was a picky eater, which emphasizes the importance of early dietary screening to discover the underlying cause of symptoms. Vitamin C deficiency should be part of the differential diagnosis in patients with unremarkable laboratory workup for infection and other diseases presenting with a Gower sign.
