Case 1: Brain MRI on admission showed bilateral subdural hematoma (a: arrows), downward shifting of the red nucleus (a: dotted arrow), and deformation of the diencephalon-midbrain due to severe brain sagging (b: asterisk). Myelographic CT showed microspurs on the ventral side of the dura at the Th11/12 level (c: arrow) and a leak of the contrast medium out of the dura (d: arrowhead). Case 2: A spinal CSF leak was suspected in spine MRI (e: arrow). A dural tear (2 x 1 mm) and a microspur were found in the ventral dura at the Th1/2 level (f: arrow). The microspur was removed (g: arrow) and the dural tear was sealed with subcutaneous fat tissue (h).

As a spinal CSF leak was suspected on the cervicothoracic MRI [Figure 1e], a myelo-CT was performed. EBP was performed. Eighteen days later, when the orthostatic headaches and brain sagging recurred on the subsequent brain MRI, the patient underwent T1/T2 microspur removal with dural repair [Figure 1f-h and Table 1].
