MRI images of atopic myelitis. (a) Cavernous angioma, which exhibits low intensity signal around the ventral side of the spinal cord at C6 vertebral level, is seen on T2WI (arrowhead). An intramedullary high-signal intensity area is found on the thoracic spinal cord at T1 vertebral level (arrow). (b) Axial image at T1 vertebral level on T2WI. An intramedullary change in signal intensity is observed on both sides of the spinal cord and around the dorsal side of the spinal cord. (c) A new intramedullary high-signal intensity area on T2WI is found on the dorsal side of the cervical spinal cord at C3 vertebral level (arrow). (d) Axial image at C3 vertebral level on T2WI. The lesion is locally observed on the left posterior funiculus.

C6 vertebral level (Figure 1(a), white arrowhead). Cavernous angioma was present in the ventral side of the right half the spinal cord (Figures 2(c), 2(d), and 2(e)) and partially extramedullary (Figure 2(c)). Intramedullary high-signal intensity on T2 weighted image (T2WI) was observed in the spinal cord at T1-2 vertebral level (Figure 1(b)) at the same time that a numbness of both lower extremities appeared. A new intramedullary high-signal intensity area on T2WI appeared at C3-4 vertebral level when the patient experienced a numbness of the left upper extremity (Figure 1(c)). A high-signal intensity area existed locally in the left posterior funiculus of the spinal cord (Figure 1(d)).

MRI images of cavernous angioma. (a) Cavernous angioma one year after SAH on T2-star sagittal image. (b) Preoperative T2-star sagittal image of cavernous angioma. The growth of the lesion is observed. (c), (d), (e) Preoperative axial image of cavernous angioma. Cavernous angioma extends laterally from the ventral side of the right half the spinal cord. Cavernous angioma is observed as a heterogenous lesion on T1 weighted image (c). Surrounding rim is seen on T2WI (d) and T2-star image (e).
