Bilateral vestibular dysfunction is a rare condition, of which peripheral disorders are most common, whereas central disorders are extremely rare. A 35-year-old woman developed fever, headache, dizziness, convulsion, and disturbance of consciousness at the same time. MRI findings were normal. Based on the neurological findings and laboratory abnormalities, she was diagnosed as having aseptic meningoencephalitis. Steroid pulse therapy successfully ameliorated her encephalitis sign. However, isolated bilateral vestibular ataxia and dizziness, together with severe decrease of Caloric nystagmus, became apparent and lasted for the following 3 months, without cerebellar/brainstem involvement.

A 64-year-old man developed cognitive impairment. A neurological examination showed hypereactive tendon reflex. A cerebrospinal fluid (CSF) examination showed a mild increase in both the number of mononuclear cells (14 cells/mm3) and the protein level (45 mg/dl). An electroencephalogram showed diffuse slow wave activity. Brain MR images revealed multifocal lesions in the limbic area and white matter regions. He was suspected to have autoimmune encephalitis and his symptoms improved after treated with methylprednisolone (1 g/day for 3 days). Despite this treatment, his mental disorders later relapsed. His condition improved after undergoing repeated treatment. Thereafter, he developed bacterial meningoencephalitis which had been caused by Listeria monocytogenes during the period of the internal administration of steroids. Antibiotics successfully cured his Listeria meningoencephalitis. He thereafter developed conjunctivitis, polyarthritis, hearing difficulties, dizziness and auricular chondritis. Based on these findings, we diagnosed the patient to have relapsing polychondritis (RP). It was thus conceivable that his cognitive impairment has been caused by CNS vasculitis associated with RP. RP therefore should be carefully taken into consideration and be included in the differential diagnosis as a possible cause for CNS vasculitis.

Orbital apex syndrome is a rare manifestation of Herpes Zoster (HZ). HZ Mmeningoencephalitis are also rare in immunocompetent persons. We report a rare case that was considered to be HZ meningoencephalitis with orbital apex syndrome in an immunocompetent female. The patient initially manifested with HZ skin lesions and lose of her left sight, diplopia, ptosis, followed by headache, neck pain, and fever, dizziness. Cerebrospinal fluid analysis showed elevation of lymphocytes and protein. A MRI abnormality was remarkable for the presence of a left cerebellum, occipital lobe as well as dura lesion. Head computed tomography and Magnetic resonance venography was normal. Corticosteroid therapy and antiviral therapy was effective to decrease the headache and skin pain. Symptoms were markedly improved after corticosteroid therapy. Three months later, we called the patient to follow up. Her meningoencephalitis symptom recovered. Her follow up brain MRI was normal. But left blindness and external ophthalmoplegia was persistent. This case suggested HZ could affect central nervous system and peripheral nervous system at the same time.

Ice pick headache, also called idiopathic or primary stabbing headache, is a unique headache type associated with ultra-brief stabs of pain, most commonly in the frontal or temporal area. It occurs predominantly in women and is estimated to affect 2-35% of the population. Unlike other headache types of short duration, such as short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), ice pick headache is not associated with any cranial autonomic symptoms but has been known to occur with nausea, vomiting, photophobia, and dizziness. It exists in two forms: primary and secondary, with examples of secondary causes being herpes zoster meningoencephalitis, meningiomas, stroke, and multiple sclerosis. Ice pick headache is one of the "indomethacin responsive headaches," but up to 35% of patients fail to show significant benefit with that treatment. Other treatment options include gabapentin, cyclooxygenase-2 inhibitors, melatonin, and external hand warming.

Hemophagocytic lymphohistiocytosis with central nervous system involvement is caused by inflammatory factor storms. The inflammatory factors invade the blood-brain barrier and further infiltrate brain tissue resulting in associated neurological and/or psychiatric symptoms in hemophagocytic lymphohistiocytosis with central nervous system involvement patients. This case report is based on a 14-year-old male patient who experienced intermittent dizziness and blurred vision about five years before admission as well as lower limb weakness and unstable walking approximately three years before admission. His brain MRI showed abnormal signals in the bilateral cerebellar hemisphere and vermis, right occipital lobe, and bilateral basal ganglia. The cerebrospinal fluid examination revealed an increase in nucleated cells, mainly monocytes, and elevated protein. He had no typical manifestation of hemophagocytic lymphohistiocytosis in the early stage, such as fever, cytopenia, or hepatosplenomegaly. He was misdiagnosed with meningoencephalitis or tuberculous meningitis. Perforin gene detection revealed a mutation in the PRF1 gene. The final diagnosis of type 2 familial hemophagocytic lymphohistiocytosis was made based on the neurological symptoms and genetic test. The possibility of hemophagocytic lymphohistiocytosis needs to be considered in patients with unexplained central nervous system symptoms, even if the patient does not have typical hemophagocytic lymphohistiocytosis symptoms, such as fever, cytopenia, or hepatosplenomegaly. We present the neurological symptoms of familial hemophagocytic lymphohistiocytosis type 2.

A novel coronavirus infection, coronavirus disease 2019 (COVID-19), is frequently associated with neuromuscular symptoms. It is characterized by taste and smell disturbances, and nonspecific symptoms such as headache and dizziness. Neuromuscular complications such as cerebrovascular disease, encephalopathy, meningoencephalitis, peripheral neuropathy, and myositis/myopathy have been reported to date. In daily clinical practice, it is important to consider COVID-19 as a differential diagnosis, because these symptoms may be the first warning signs.
