Six patients had other lesions such as pineal tumor
, hemangioblastoma, astrocytoma, or metastasis.
Although her retinoblastomas were successfully treated in infancy, at age 2 years she was diagnosed with a pineal tumor
, a common occurrence since these children face a sharp increase in the risk of developing multiple cancers.
In both instances, the dural tumors occurred directly in the trajectory of the original biopsy site of her pineal tumor
, according to her neurosurgeon.
Computed tomographic (CT) scan and magnetic resonance imaging (MRI) showed the presence of triventricular hydrocephalus associated with a 30-mm pineal tumor, partially calcified (Figure 1, A).
Triventricular hydrocephalus associated with a pineal tumor was visible on the CT scan and MRI plates (Figure 3, A).
Primitive pineal tumor with retinoblastomatous and retinal/ciliary epithelial differentiation: an immunohistochemicai study.
Neuroepithelial and ectomesenchymal differentiation in a primitive pineal tumor (pineal analage tumor).
Among the indications for ETV we include all of the following: obstructive triventricular hydrocephalus due to aqueductal stenosis, isolated lateral ventricular hydrocephalus, Dandy-Walker malformation, intraventricular hemorrhages, posterior fossa masses, pineal tumors
and NPH (5-8).
52) Among the pineal tumors
arising from germ cells, teratomas commonly have dense calcifications.
