Hirayama Disease: Magnetic Resonance Imaging Manifestations and Single Centre Experience

Purpose: A retrospective study to evaluate various MR imaging spectrums of clinically diagnosed cases Hirayama disease. Materials and Method: This included a review images 13 patients on the hospital information system who underwent evaluation for suspected disease 3 Tesla MRI scanner in postcontrast neutral flexion positions. Images were evaluated following findings: Localised lower cervical cord atrophy, asymmetric flattening, Abnormal curvature, an Increased signal T2WS, Loss attachment between posterior dura lamina, presence flow void with enhancement. Observations: Lower anterior dural shift flexion, enhancement epidural component was found thirteen out (100%), followed by hyperintense T2WS which 11 patients. subjacent lamina abnormal curvature spine 9 (91.3%), prominent eight (61.5%), thoracic extension enhancing five (38.4%).
