title: Gowers intrasyringal hemorrhage. Case report and review of the literature.
abstract: The concept of hemorrhage in a preexisting syringomyelic cavity was first described by Gowers in 1904. Since its first description only 13 cases have been reported. The aims of this report are to describe a new case, bring this entity to wider attention, and summarize the existing literature on the subject. This 36-year-old woman presented with progressive gait disturbance and unsteadiness. Physical examination revealed incomplete quadriparesis, predominantly on the left side, and hypesthesia below C-7. Magnetic resonance imaging revealed hematomyelia characterized by a heterogeneous hyperintense signal within the central cervical cord. A liquefied well-limited hematoma was evacuated. The postoperative course was uneventful; a near-complete recovery was observed at the 7-year follow-up examination. Most cases of intrasyringal hemorrhage (ISH) have occurred in syringomyelic cavities associated with scoliosis or Chiari malformation Type I. Although there is no specific clinical picture associated with this entity, it can be characterized by three neurological forms: 1) sudden onset or rapid development of signs and symptoms, 2) acute worsening of symptoms that may improve but leaving greater neurological dysfunction than before the previous episode, and 3) ISH may initiate progressive deterioration in a patient with known syringomyelia. Intrasyringal bleeding is most probably caused by a sudden dilation of the syringomyelic cavity, which may provoke rupture of the intrasyringal vessels by an acute distension of the accompanying strands. Magnetic resonance imaging is the most accurate diagnostic modality, and recognition of ISH can lead to early, safe, and efficient surgical treatment.
