RESUMO
Paraneoplastic neurological disorders are a rare complication of multiple neoplasms, such as lung, testis, and breast, and can be associated with positive antibody anti-Hu (anti-neuronal nuclear antibody type 1 or ANNA-1), anti-Ta, anti-Ma, and uncharacterized antibody, or be antibody-negative. Early treatment of the underlying tumor is the most likely modality that will lead to regression of the paraneoplastic neurological symptoms. Here, we present a case of a 73-year-old female with new-onset seizure activity from ANNA-1 encephalitis found to have undiagnosed small cell lung cancer to highlight the need for further workup for malignancy.
RESUMO
Human herpesvirus 6 (HHV-6) is one of the most prevalent childhood viruses. HHV-6 reactivation in allogeneic hematopoietic cell transplant recipients and solid organ transplant recipients is well described in medical literature. We present a case of HHV-6 reactivation causing encephalitis, which is rare in immunocompetent adults.
RESUMO
Nonketogenic hyperglycemic hemichorea, also recognized as diabetic striatopathy, is a rare manifestation of diabetes mellitus. The diagnosis of nonketotic hyperglycemic hemichorea is usually made through imaging along with a corresponding clinical picture. Early identification and treatment can lead to complete resolution of the symptoms and better patient outcomes. Here we present a 49-year-old female patient, with a past medical history of poorly controlled type 2 diabetes mellitus and prior left index finger amputation as a complication of her diabetes, who presented for evaluation of a two-week duration of sudden-onset left upper extremity choreiform movements.
