Abstract
A 56-yr-old man was admitted with a 3-yr history of recurrent petechial rash, and monarthritis right knee. Examination revealed an extensive purpuric rash over the abdomen, legs and bruising over the knees and feet. Corkscrew hairs were present on the abdominal wall. A skin biopsy showed prominent interstitial haemorrhage involving the superficial and mid dermis without capillaritis, consistent with scurvy. MRI showed multiple small focal areas of marrow oedema throughout the metaphyseal regions of the distal femur and proximal tibia on T1-weighted and PD/SPIR images. A diagnosis of scurvy was made. His diet was completely devoid of fresh fruit and vegetables. Vitamin C replacement resulted in resolution of the rash. Repeat MRI (after 6 months) showed complete resolution of the bone marrow lesions.
