“…1,5,13) Our patient presented with paraparesis, paresthesia, and urinary incontinence. Multiple arachnoid cysts which compress the spinal cord from the ventral side might contribute to paraparesis as a pyramidal sign.…”

“…According to previous studies, ruptured aneurysm located in the posterior circulation may pose a higher risk for adhesive arachnoiditis compared with aneurysm in the anterior circulation. 1,5,9,10,13,14) We speculate that the hematoma volume in the spinal subarachnoid space is related with the occurrence of spinal arachnoiditis. Adhesive arachnoiditis occurred in cases treated with both clipping and coiling, so the chronic inflammatory response of the pia-arachnoid mater persisting due to SAH is thought to be a cause of spinal arachnoiditis.…”

A 66-year-old woman with primary Sjogren syndrome developed syringomyelia following two episodes of subarachnoid hemorrhage (SAH) due to the rupture of basilar artery aneurysms. Gait disturbance and abnormal sensation with pain over the foot and abdomen appeared 3 years after the last SAH. Magnetic resonance (MR) imaging revealed a syringomyelia throughout the thoracic cord, from the T2 to T11 levels. In addition, the thoracic cord was compressed by multiple arachnoid cysts in the ventral side of spinal cord. Computed tomography myelography revealed complete block of cerebrospinal fluid (CSF) flow at the T7 level. Surgery for microlysis of the adhesions and restoration of the CSF flow pathway was performed. Postoperatively, leg motor function slowly improved and she could walk unaided. However, abdominal paresthesia was persisted. Postoperative MR imaging revealed diminished size of the syrinxes. We should recognize syringomyelia and arachnoid cysts due to adhesive arachnoiditis as a late complication of SAH. Microlysis of the adhesions focusing on the lesion thought to be the cause of the symptoms is one of the choices to treat massive syringomyelia and arachnoid cysts associated with arachnoiditis following SAH.

“…Neurosurgery consult suggested no indication for surgical decompression with current improvements, as surgery itself might aggravate the inflammation process. 3 DISCUSSION Adhesive arachnoiditis refers to a severe type of inflammation in the arachnoid mater. There have been several case reports regarding adhesive arachnoiditis occurring following subarachnoid hemorrhage.…”

“…There have been several case reports regarding adhesive arachnoiditis occurring following subarachnoid hemorrhage. 3,4 Post-subarachnoid hemorrhage arachnoiditis was mostly seen in ruptured aneurysm in the posterior circulation. 3 However, this is one case identified later with moyamoya disease rather than aneurysm.…”
