Opsoclonus-myoclonus is a rare neurological paraneoplastic syndrome associated with breast cancer and the presence of anti-Ri antibody. We presented a case of a 79-year-old woman with this syndrome and a small invasive ductal carcinoma [pT1aN0(sn)M0], whose symptoms improved 3 months following her
Opsoclonus-myoclonus paraneoplastic syndrome is a medical condition that includes opsoclonus along with diffuse or focal body myoclonus and truncal titubation with or without ataxia and other cerebellar signs. This rare neurological syndrome is poorly understood and can result in long-term
Opsoclonus-myoclonus-ataxia (OMA) syndrome is a rare neurological disorder, characterized by a rapid onset of generalized myoclonus in association with chaotic multi-directional eye movements and, less frequently, cerebellar ataxia. OMA is commonly related to a paraneoplastic process, specifically
The aim of this article is to review the paraneoplastic opsoclonus-myoclonus syndrome (POMS). Opsoclonus is characterized by involuntary, arrhythmic, chaotic, multi-directional saccades with horizontal, vertical and torsional components, and it is commonly accompanied by cerebellar ataxia and
The opsoclonus-myoclonus syndrome is a rare entity as a paraneoplastic disorder usually associated to neuroblastoma in children and breast cancer or oat-cell lung carcinoma in adults. The association of opsoclonus-myoclonus syndrome and ovarian carcinoma is very unusual, to our knowledge there is
Paraneoplastic neurological syndrome is associated with anti-Ri antibodies, which are typically present with opsoclonus-myoclonus-ataxia. Human epidermal growth factor receptor 2 (HER2) overexpression is present in 15%-25% of breast cancer and is associated with poor prognosis. There are a few
BACKGROUND
Paraneoplastic neurological disorders associated with anti-Ri-antibodies, which are typically present with opsoclonus-myoclonus-ataxia. Most cases with anti-Ri-antibodyassociated paraneoplastic syndrome due to breast cancer occur in women - its occurrence in men is extremely
We reported a case of opsoclonus-myoclonus syndrome. A 63-year-old man was admitted to Kenwakai Hospital with rapidly progressing symptoms, including lumbago, whole body pain, vertigo, nausea, and anorexia. He became bed-ridden because of severe vertigo and truncal ataxia. Five days after admission,
Four cases of opsoclonus in adults are reported. In all cases, it was associated with myoclonus and cerebellar syndrome. In 2 cases, the clinical and biological picture was suggestive of an infectious origin, and the patients recovered. The last cases are paraneoplastic opsoclonus revelating a
Opsoclonus-myoclonus syndrome (OMS) is a rare paraneoplastic disorder that is most often seen in association with pediatric neuroblastoma, breast cancer, small cell lung cancer, and prostate cancer. There are only three previously documented cases relating paraneoplastic OMS to ovarian cancer. We
Paraneoplastic syndromes are the rarest neurological complications in patients with cancer. The neurological paraneoplastic syndromes that are mainly associated with breast cancer are subacute cerebellar degeneration, paraneoplastic retinopathy, opsoclonus-myoclonus syndrome, lower motor neuron
Several antineuronal antibodies are associated with paraneoplastic cerebellar degeneration. Anti-Ri is one of these antibodies in some cases but it is more commonly associated with paraneoplastic opsoclonus myoclonus in the context of gynecological neoplasia. Anti-Ri autoantibodies are thought to be
Breast cancer is the most frequent cause of cancer of women in much of the world. In countries with screening programs, breast cancer is often detected before clinical symptoms are apparent, but occasionally the occurrence of a paraneoplastic syndrome precedes the identification of cancer. In breast
