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.
Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma.
Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [1] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration , and alcoholic or nutritional cerebellar degeneration. [ 2 ]
Post-viral cerebellar ataxia also known as acute cerebellitis and acute cerebellar ataxia (ACA) is a disease characterized by the sudden onset of ataxia following a viral infection. [1] The disease affects the function or structure of the cerebellum region in the brain.
Lhermitte–Duclos disease (LDD) (English: / ˌ l ɛər ˈ m iː t ˌ d uː ˈ k l oʊ /), also called dysplastic gangliocytoma of the cerebellum (DGC), is a rare, slowly growing tumor of the cerebellum, a gangliocytoma sometimes considered to be a hamartoma, characterized by diffuse hypertrophy of the granular layer of the cerebellum.
Acute cerebellar ataxia is a rare initial presenting feature of NM, particularly in gastric cancer. Paraneoplastic cerebellar degeneration (PCD) is a well-known cause of cerebellar ataxia associated with neoplastic disorders, and commonly, with positivity for various anti-neuronal antibodies. [13]
Brain metastasis in the right cerebral hemisphere from lung cancer shown on T1-weighted magnetic resonance imaging with intravenous contrast.. Because different parts of the brain are responsible for different functions, symptoms vary depending on the site of metastasis within the brain.
Glioblastomas are the most common primary malignancies to hemorrhage while thyroid, renal cell carcinoma, melanoma, and lung cancer are the most common causes of hemorrhage from metastatic disease. Other causes of intraparenchymal hemorrhage include hemorrhagic transformation of infarction which is usually in a classic vascular distribution and ...
