On the management of neonatal tentorial damage. Eight case reports and a review of the literature.
From the history of 15 personal patients--8 reported here in extenso--and from 63 patients in the literature with the diagnosis of posterior fossa subdural haemorrhage during life, we discuss the possibility of detecting tentorial damage on computed tomography (CT) and ultrasound (US) scan. The association of a (peri)cerebellar haemorrhage with peritentorial bleeding around the straight sinus and a subdural haemorrhage between both occipital cerebral lobes is suggestive of tentorial laceration(s). Both coronal CT scan and sagittal US scan are very helpful in locating these haemorrhages near the falco-tentorial junction. The conservative management of one of our infants with very extensive but asymmetric posterior fossa haemorrhage, leading to resorptive hydrocephalus, is compared with both surgical and conservative treatment of patients from the literature. Two reasons that warrant neurosurgical intervention are: life-threatening brain-stem compression--as in one of our own patients--and acute obstructive hydrocephalus. Craniotomy of the posterior fossa within the neonatal period does not prevent later-onset resorptive hydrocephalus. The communicating nature of this latter process is adequately demonstrated by lumbar isotope cisternography. Finally, neonatal posterior fossa subdural haemorrhage is one of the many causes of cyst-like structures behind the cerebellum.
