Melanotic neuroectodermal neurocranial tumor of infancy of extra-intra- and subdural right temporal location: CT examination, surgical treatment, literature review
1986
: A melanotic neuroectodermal neurocranial tumor of infancy of extra-intra-subdural right temporal location, examined by CT and successfully operated in a 33-month-old boy is reported in context with the literature. Out of 30 cases (including our case) of melanotic neuroectodermal neurocranial and intracranial tumors (MNNIT) 18 were located in the neurocranium (MNNT) and 12 intracranially, i.e. in the brain and cerebellum (MNIT). 23 tumors were located medially (11 at the anterior fontanel, one at the posterior fontanel, one in the 3rd ventricle, one in the sella turcica, one in the pineal region, 8 in the cerebellar vermis) and 7 laterally (five involved the temporal bone, one of which with intracranial propagation (our case), one in the temporal lobe of the brain, one in the skull posterior to the mastoid process). Twenty-eight cases were children (16 boys, 8 girls, four not stated), two adults. The location is important in respect to biology and surgery: MNNIT can be grouped as to its relation to the arachnoid barrier layer into malignant and benign. MNIT localised medially subarachnoidally are malignant. MNNT of small dimensions localised medially and laterally extraarachnoidally are benign. MNNT of extreme dimensions localised medially extra-intradurally are also benign, but difficult to treat. In the MNNT when diagnosed early and operated radically, the mortality can be lowered. Our case, presented on CT (1978) as first case of combined extra-intra-subdural location, represents the 173rd MNT and the 18th related to neurocranium.
