Unique presentation and management of Gowers intrasyringal hemorrhage.

Intrasyringal hemorrhage was first described in literature in the renowned by Sir William Richard Gowers [Gowers W. A lecture on syringal haemorrhage into the spinal cord. Lancet [Internet]; 162(4180):993-997. [cited 2019 August 19]. Available from https://www.sciencedirect.com/science/article/pii/S0140673601362785]. The pathophysiology of this disease is a hemorrhage within a preexisting intramedullary fluid-filled cavity or hydrosyringomyelia in the spinal cord. Most common symptoms of this disease are numbness, weakness, paresthesia in the extremities and gait disturbances. Since first noted in 1903, there have been just fourteen confirmed cases of this disease reported in literature, making it extremely rare and difficult to study. Here we discuss a unique presentation of Gowers intrasyringal hemorrhage. The patient is a male in his late teens with no prior established neurological history. He presented at our institution four days post suspected injury with persistent mild left upper extremity numbness and weakness. The patient was admitted and underwent an MRI of the cervical spine without intravenous contrast. The imaging findings confirm subacute on chronic Gowers intrasyringal hemorrhage in the setting of a Chiari 1 malformation. This patient underwent neurosurgical intervention four months post initial presentation and had complete postoperative resolution of his interval non-progressive but persistent symptoms.: This unique case suggests immediate surgical intervention may not always be necessary for treating Gowers intrasyringal hemorrhage.
