The cerebellopontine angle syndrome is a distinct neurological syndrome of deficits that can arise due to the closeness of the cerebellopontine angle to specific cranial nerves. [1] Indications include unilateral hearing loss (85%), speech impediments, disequilibrium, tremors or other loss of motor control.
The cerebellopontine angle (CPA) (Latin: angulus cerebellopontinus) is located between the cerebellum and the pons. [1] The cerebellopontine angle is the site of the cerebellopontine angle cistern. [2] The cerebellopontine angle is also the site of a set of neurological disorders known as the cerebellopontine angle syndrome.
IAC tumors that grow beyond 1.5 cm in diameter expand into the relatively empty space of the cerebellopontine angle, taking on the characteristic 'ice-cream-cone' appearance seen on MRIs. As 'space-occupying-lesions,' the tumors can reach 3 to 4 cm or more in size and infringe on the facial nerve (facial expression) and trigeminal nerve (facial ...
Paraneoplastic cerebellar degeneration (PCD) is a paraneoplastic syndrome associated with a broad variety of tumors including lung cancer, ovarian cancer, breast cancer, Hodgkin’s lymphoma and others. PCD is a rare condition that occurs in less than 1% of cancer patients.
Neurocutaneous melanosis syndrome [1] A 13-year-old with a giant congenital melanocytic nevus, or "bathing trunk" Neurocutaneous melanosis is a congenital disorder characterized by the presence of congenital melanocytic nevi on the skin and melanocytic tumors in the leptomeninges of the central nervous system .

Central pontine myelinolysis; Other names: Osmotic demyelination syndrome, central pontine demyelination: Axial fat-saturated T2-weighted image showing hyperintensity in the pons with sparing of the peripheral fibers, the patient was an alcoholic admitted with a serum Na of 101 treated with hypertonic saline, he was left with quadriparesis, dysarthria, and altered mental status
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
These tumors may exhibit enhanced cellularity and mitotic activity. Although the likelihood of these tumors developing into cancer is extremely low, local recurrence is possible in around half of cases. On MRI, it usually shows hyper or iso-intensity on T1-weighted images and heterogenous hyperintensities on T2 weighted images.
