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.
The new procedure developed by Shahinian involves making a dime-size opening behind the ear, inserting a small endoscope over the top of the cerebellum and through a natural pathway accessing the deep-seated pineal tumor.
medical director of The Skull Base Institute in Los Angeles, has developed a minimally invasive approach to removing pineal tumors so called as they are shaped like pine cones.
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.
Our collaboration has already resulted in drastic improvements in instrumentation, which has helped countless patients suffering from acoustic neuromas, meningiomas, pineal tumors
and pituitary tumors as well as abnormalities such as hemifacial spasms and trigeminal neuralgia.
