A patient is presented who suffered a strokelike event during life that resulted in a hemisensory dificit for some modalities. On pathological examination of the brain, the lesion responsible for the deficit was found to be a small slit hemorrhage located in the posterior limb of the internal capsule adjacent to and minimally involving the thalamus. Clinicopathological correlation suggests that the sensory thalamocortical radiations must lie farther posterior in the posterior limb of the internal capsule than the corticospinal motor fibers, and that they probably lie adjacent to the thalamus. The case emphasizes that small slit hemorrhages deep in the brain, although rare, must be considered in the differential diagnosis of sudden hemisensory deficits.
本文报告了一名患者，其生前发生了类似中风的事件，导致某些感觉模式出现偏身感觉障碍。在对大脑进行病理检查时，发现导致该障碍的病变是位于内囊后肢、紧邻丘脑且轻微累及丘脑的小裂隙出血。临床病理相关性提示，感觉丘脑皮质辐射在内囊后肢的位置一定比皮质脊髓运动纤维更靠后，并且它们可能紧邻丘脑。该病例强调，脑深部的小裂隙出血虽然罕见，但在突发偏身感觉障碍的鉴别诊断中必须予以考虑。
