[Neonatal intracerebral bleeding as initial symptom of gliomatosis cerebri WHO III--neurological outcome after partial hemispherectomy]. / Eine neonatale intrazerebrale Blutung als Initialsymptom einer Gliomatosis cerebri WHO III--neurologisches Outcome nach partieller Hemisphärektomie.

INTRODUCTION: Anaplastic astrocytomas presenting as gliomatosis cerebri in neonates are extremely rare. Tumours in newborns are mostly of neuroectodermal origin. CASE REPORT: We report about a female newborn at term [birth weight 3 600 g (P 90), head circumference 35 cm (P 95) APGAR 9/10/10] with an intracerebral partially clotted bleeding in the left parieto-occipital region. The bleeding was expansive leading to axial and lateral cerebral herniation. The intracerebral bleeding in the left occipital region was surgically removed. Macroscopically no solid tumour was seen, but small fragments of an anaplastic astrocytic tumour (WHO grade III) were diagnosed histologically. After surgery, no remaining tumour was visible in the MRI. 6 weeks later, a recurrent tumour (4×4 cm) was found in the area of the initial bleeding. Further treatment was initially refused by the parents. The child was readmitted to our hospital at the age of 11 months in good clinical condition and presented with left-sided hemiparesis, right-sided hemianopsia and intermittent strabismus convergens alternans. Because of the good clinical condition further therapeutic treatment was initiated. Due to the final extension of the tumour into the temporal, parietal and occipital lobes, a gliomatosis cerebri WHO III was diagnosed. An extended partial hemispherectomy was done. After neurosurgery, no further neurological failures occurred. In the follow-up examination, MRI showed no relapse of the tumour. Chemotherapy according to the HIT SKK protocol was initiated. A relapse did not occur over a follow-up of 2 years. CONCLUSION: This is a rare case report of a congenital gliomatosis cerebri WHO grade III, treated with partial hemispherectomy, leading to a good clinical and neurological long-term outcome.
