  Fig. 1 Findings of MRI and nerve conduction studies in both patients. Sagittal and axial T2-weighted images exhibited hyperintensities in the cervical cord region with an ‘inverted V sign’ (arrows) typical of subacute combined degeneration (A and C). Nerve conduction studies revealed axonal motor neuropathy (B and D). *Abnormal values. ADM: abductor digiti minimi muscle, AH: abductor hallucis brevis muscle, APB: abductor pollicis brevis muscle, EDB: extensor digitorum brevis muscle, FH: fibular head, LT: left, ND: not done, NR: no response, PF: popliteal fossa, RT: right, TA: tibialis anterior muscle.
