| Popis: | subdural hematoma (SSDH) following minor trauma in a 54-yearold man. Initially, the patient slipped on ice, falling on his back and occiput. Three weeks later he experienced an episode of acute lowback pain and increasing bitemporal headache. A computerized tomography scan displayed a small bihemispherical chronic SDH. This lesion was treated conservatively; however, the level of lowback pain fluctuated and was resistant to medical treatment. The patient developed progressive compression of the cauda equina. Magnetic resonance (MR) imaging revealed a sharply defined mass lesion filling the entire dural sac and compromising the cauda equina ventrally and dorsally (Fig. 1); this was consistent with a chronic SDH. Progressive symptoms led to surgical evacuation. Surgical and histopathological findings confirmed the diagnosis. The patient recovered completely, and 6-month follow-up MR imaging showed no residual or recurrent spinal hematoma (Fig. 2). Chronic SSDH is a very rare entity among spinal hematomas. Approximately 15 cases have been reported in the literature. Anticoagulant therapy, blood dyscrasias, trauma, vascular malformations, lumbar puncture, and surgery have been proposed as causative factors, and spontaneous cases have been described as well.1,2, 4,5 Symptoms are often uncharacteristic and can be misleading. Myelography has been supplanted by MR imaging as the method of choice to study spinal hematomas to determine their extent and to distinguish between intradural and extradural blood.3 The pathogenic mechanism of SSDH is still unclear. Unlike its intracranial counterpart, the spinal subdural space lacks vessels of sufficient size to be the source of the bleeding.1,4 Our case, documented by radiological, surgical, and histopathological findings, suggests that SSDH is a venous hemorrhage that can maintain a chronic course similar to that of intracranial SDHs. Chronic SSDH has been considered to have an uncertain prognosis; however, good results can be expected with early diagnosis and prompt treatment. |
