本文分析31例散发性病毒性脑炎,发现患者的临床症状与病理类型有密切的关系,依病变的范围及其严重程度,可分三型:(1)弥漫型,(2)脑干型,(3)假瘤型。分别叙述各型的病理变化,并指出本病病理方面的基本特点;(1)病变范围广泛,可累及整个中枢神经系统的组织;(2)脑内病变的程度,一般白质重于灰质;(3)病灶特点为大片、边界不清的水肿、脱髓鞘、软化、坏死和弥漫性的小胶质增生,可形成局限性的假瘤性肿块,但不形成脓肿;(4)血管套明显,为单核细胞、淋巴细胞、淋巴母细胞、浆细胞;(5)大部分病例可治愈,部分病例的病变广泛严重,可在急性期死亡或发展成脑萎缩。此外扼要讨论病理诊断和病因等。
This article analyzes 31 cases of sporadic viral encephalitis and found that the clinical symptoms of patients with pathological types are closely related, according to the extent of the lesion and its severity, can be divided into three types: (1) diffuse, (2) brain stem , (3) pseudotumor type. (2) the degree of brain lesions, the general weight of the white matter in the gray matter; ((2) the extent of the lesion in the brain, the general weight of the white matter in the gray matter; 3) The lesions are characterized by large, borderline unclear edema, demyelination, softening, necrosis and diffuse microglial hyperplasia that can form localized pseudotumor masses but not abscesses; (4) , For monocytes, lymphocytes, lymphoblasts, plasma cells; (5) Most cases can be cured, in some cases extensive extensive disease, can die in the acute phase or develop into brain atrophy. In addition to a brief discussion of pathological diagnosis and etiology.
