“…It is effective in secondary glaucoma, especially when neovascularization is present. 15,18 The latency of the treatment effect is relatively short. The patients with primary open angle glaucoma suffer less pain, their IOP is less elevated, and their disease is mainly expressed by visual loss as a manifestation of the optic neuropathy.…”

We describe the clinical features and MRimaging findings of spontaneous spinal subarachnoid hemorrhage located in the lumbar spine associated with subdural hematoma at a higher, thoracic level in a 66-yearold man without neurological deficit. The sequential MRimaging changes of hemorrhage at various stages in its evolution are portrayed. The possible pathogenetic mechanism for these very unusual, combined hemorrhages in both spinal compartments is discussed.Keywords Spontaneous . Subarachnoid hemorrhage . Subdural hematoma . Spine . MRI Case reportA 66-year-old man presented to the emergency department with history of 1 week of lower back pain, headache, and left lower limb pain. He had no history of trauma, physical exertion, anticoagulant therapy, or any known bleeding dyscrasias. The patient had a fever of 100°F. He did not develop paraparesis, loss of sensation, numbness or urinary dysfunction. Physical examination disclosed localized tenderness over the lumbar spine. Neurologic examination was normal. Pertinent laboratory data were within normal limits except for mild elevation of lactate dehydrogenase (262 IU/l).Urgent CT scan of the head showed no evidence of subarachnoid or intracerebral hemorrhage. MR imaging of the spine performed on the same day of admission demonstrated a linear subarachnoid lesion extending from L1 to L5, ventral to the conus medullaris and cauda equina. The subarachnoid process was of increased signal intensity relative to the spinal cord on both T1-and T2-weighted images; which was suggestive of subacute hemorrhage (Fig. 1). In addition, a subdural lesion with a smooth contour was seen extending from T11 to T12 vertebrae and overlying the ventrolateral aspect of the spinal canal. This abnormal area displayed predominantly increased signal intensity relative to the spinal cord on T1-weighted images. On T2-weighted images, the lesion showed heterogeneously increased signal intensity with a focus of low signal intensity compatible with subacute hematoma containing deoxyhemoglobin (Fig. 2). The subdural hematoma was compressing the adjacent spinal cord without obvious signal changes within the cord. No MR-imaging evidence of vascular abnormalities was visualized in the spine. Although the patient was advised to undergo spinal angiography, he did not consent to.
