(15) demonstrates, looking only at immunosuppressive and immunomodulatory treatments, there was no obvious relationship between different treatments and outcome. Thus, based on our literature review, we consider that, early interventions against the improved intracranial pressure due to the rapid increasing mind edema, especially craniotomy, can change the fulminant course of the disease. huge remaining temporo-occipital white matter lesion with standard morphology for AHLE. Both individuals received craniotomy within the 1st 24 h and consequent immunosuppressive-immunomodulatory treatment and survived with minimal deficits. Out of 35 supratentorial reported AHLE instances, seven individuals received decompressive craniotomy. Comparing all supratentorial instances, individuals who received craniotomy were more likely to have a good end result (71 vs. 29%). Summary: Due to early control of the intracranial pressure, particularly due to early craniotomy; analysis per biopsy; and immediate start of immunosuppressive-immunomodulatory treatments (cortisone pulse, plasma exchanges), both individuals survived with minimal sequelae. Craniotomy takes on an Diacetylkorseveriline important part and should be considered early on in individuals with probable AHLE. Diacetylkorseveriline = 5; Table 3, Fisher’s precise test: = 0.0754). Three of the seven individuals who received craniotomy experienced no deficit, two experienced minimal sequelae, and only two individuals died (29%). The initial biopsy of one of those two individuals (5) showed a neutrophil predominance and did not lead to the direct analysis of AHLE. Therefore, a differential analysis of pneumonia with hematogenous spread to the brain was suspected, and the craniectomy was combined with antibiotics instead of a combination with immunosuppressive therapy. The other individual who died despite craniectomy experienced a 2-week history of illness and refused to go to the hospital at first (42). Also, the MRI could not be obtained within the 1st day after admission, which led to a delay in immunosuppressive treatment. In the non-operated group, 71% (= 20) of the individuals experienced an unfavorable end result (7 individuals severely handicapped, 13 died), and 29% survived with minimal (= 6) to no deficit (= 2). This difference, however, just did not reach statistical significance (Fisher’s precise test: p = 0.0754).

The disease mostly affects young males but is also reported in individuals of all age Diacetylkorseveriline groups (16). Even with early aggressive immunosuppressive treatment, AHLE can be a devastating condition in terms of mortality and severe neurological sequelae. Probably one of the most detailed evaluations on AHLE by Grzonka et al. (15) demonstrates, looking only at immunosuppressive and immunomodulatory treatments, there was no clear relationship between different treatments and outcome. Therefore, based on our literature review, we consider that, early interventions against the improved intracranial pressure due to the quick increasing mind edema, especially craniotomy, can change the fulminant course of the disease. We suggest that better prognosis can be expected when craniotomy is performed early, together with a consequent immunosuppressive-immunomodulatory treatment at the same time than medical treatment only. Despite the be concerned that sudden decompression could aggravate intracerebral bleedings of the hemorrhagic encephalitis, the mass effect of the disease seems to be the life-limiting element. This is in line with a review on decompressive craniotomy in viral encephalitis individuals with mind herniation (47) and also in individuals with spontaneous intracerebral hemorrhage (48). They also suggest that, Diacetylkorseveriline in those cases, a better prognosis without increasing the hemorrhage can be expected when craniotomy is performed in addition to medical treatment only. We believe that the present data support the decision for an early medical decompression in individuals with severe and quick AHLE and should be considered early on. Control of the intracranial pressure seems to be an important part of the therapy concept in addition to early immunosuppression. Still, this is the conclusion based on a review of literature with a relative low number of cases and, therefore, only a low level of evidence. Normally, we don’t expect that, in such a rare and severe disease, a prospective controlled study can be done.
