Parkinsonism secondary to intracranial mass lesions usually results from compression or distortion of the basal ganglia. Secondary parkinsonism due to midbrain infiltration or compression is rare and generally associated with other neurologic signs caused by pyramidal tract and/or cranial nerve involvement. We report a case of 30-year-old woman in whom mild parkinsonism was the major clinical m...

Iodine requirements are increased ≥ 50% during pregnancy. Iodine deficiency during pregnancy can cause maternal and fetal hypothyroidism and impair neurological development of the fetus. The consequences depend upon the timing and severity of the hypothyroidism; the most severe manifestation is cretinism. In moderate-to-severely iodine-deficient areas, controlled studies have demonstrated that ...

RATIONALE Neurosarcoidosis (NS) is an uncommon manifestation of systemic sarcoidosis, with a propensity for middle-agedwomen. Often discovered only at autopsy, rates of neurologic involvement (5%-10%) reported in the literature underscore a lack of sensitivity and specificity in current diagnostic methods. PATIENT CONCERNS Herein, we describe a 53-year-old woman who presented with gait imbala...

Intravascular lymphomatosis (IL) is a rare and generally fatal disease characterized by proliferation of large lymphoma cells almost exclusively within the lumen of small blood vessels. The skin and central nervous systems are typically affected, but involvement of other organs, such as lung, has been described. Predominant lung involvement without cutaneous and neurologic manifestation is very...

Sjögren’s syndrome is a slowly progressing autoimmune disease characterized by lymphocytic infiltration of the exocrine glands, mainly the lacrimal and salivary glands, resulting in their impaired secretory function. Systemic involvement and symptoms of cutaneous, respiratory, renal, hepatic, neurologic, and vascular systems often occur.1 Renal involvement is a well recognized extra glandular m...

PURPOSE Vogt-Koyanagi-Harada (VKH) disease is an autoimmune disorder against melanocytes. Polymorphisms of the protein tyrosine phosphatase non-receptor 22 gene (PTPN22) have recently been reported to be associated with susceptibility to several autoimmune diseases. In this study, genetic susceptibility to VKH disease was investigated by screening for single nucleotide polymorphisms (SNPs) of P...

Neurofibromatosis type 1 (NF1) or Von Recklinghausen disease manifests as cutaneous café-au-lait spots and neurofibromas. It is one of the most common autosomal dominant genetic diseases. It is extremely variable in its individual manifestation. Cutaneous and neurologic symptoms are the most common manifestations but it can also affect other organs including eyes, bones and other areas. Lisch n...

Bee stings are commonly encountered worldwide. Various manifestations after bee sting have been described including local reactions which are common, systemic responses such as anaphylaxis, diffuse intravascular coagulation and hemolysis. We report a case of a 74-year-old man who developed neurologic deficit 5 hours after bee stings, which was confirmed to be left frontal infarction on brain CT...

Cortical blindness is rarely an ictal manifestation. We report the case of a man who developed transient cortical blindness followed by permanent visual deficits during repeated partial seizures. Intermittent visual impairment began at age 14 years. After he had the first generalized seizure at age 28 years, neurologic, ophthalmologic, angiographic, and brain computed tomographic (CT) examinati...

Although catatonia is a well-known psychiatric syndrome, there are many possible systemic and neurological etiologies. The aim of this case report was to present a case of a patient with cerebral venous sinus thrombosis and infarction in which catatonia was the clinical manifestation of a possible nonconvulsive status epilepticus. To our knowledge, only one such case has been reported in the li...
