We reported a 71 years old woman, with history of rest and postural tremor, bradykinesia and memory problems. In her dynamic MRI, a contrastenhanced tumor in the cerebellopontine (CP) angle was found which was compatible with a meningioma. 99mTc-TRODAT SPECT showed decreased activity in the left putamen, indicating idiopathic Parkinson disease. There was also a focus of increased activity on the right side of the skull base, which was compatible with meningioma in MRI.

Parkinson's disease (PD), the second most prevalent neurodegenerative disorder, has been related with weight loss and energy balance. Some studies showed that leptin might be playing an important role in satiety, energy balance and immune response. The aim of this study was to evaluate serum leptin level in patients with PD and its association with clinical severity.
In this cross-sectional study, 35 patients with PD and 51 healthy controls (HCs), matched for age, sex and body mass index (BMI), were recruited. Serum leptin level was measured and clinical characteristics and demographic data of patients were recorded.
The mean age of patients with PD and HCs were 59.80 ± 11.40 and 62.18 ± 11.60 years, respectively. Serum leptin concentration was not statistically different between patients with PD and HCs (21.1 ± 23.1 ng/ml vs 25.9 ± 21.8 ng/ml, P = 0.280). There was no relation between plasma level of leptin and clinical severity of patients with PD.
Our findings suggest that serum level of leptin is neither implicated in the pathogenesis of PD, nor decreases as disease progresses.

Brucellosis is a zoonotic infection with high distribution all over the world and has many clinical manifestations, one of which is neurobrucellosis (NB).. Our case was a 78-year-old man who presented acute decreased level of consciousness, acute parkinsonism signs and hyponatremia due to syndrome of inappropriate antidiuretic hormone secretion (SIADH), which was caused by brucellosis.. Neurobrucellosis is a rare presentation of brucellosis and should be considered when neurological problems cannot be explained by other etiology especially in endemic areas..

Multiple sclerosis (MS) is an autoimmune inflammatory disease that affects the central nervous system. Except tremor, other movement disorders such as Parkinsonism are less frequent in MS. However, some investigations have shown inflammatory and autoimmune aspects of Parkinson’s disease. In this study, we report eight new cases of MS who present Parkinson’s disease. This retrospective population-based study was carried out on Isfahan MS society between April 2003 and July 2012. A total of 3792 patients with MS were surveyed for Parkinson’s disease. Parkinson’s disease was approved according to “UK Parkinson disease Brain Bank” criteria. Eligible cases were invited to have an interview with a neurologist. MRI was carried out according to the baseline. We identified eight patients (three men and five women) who present MS and Parkinson’s disease. The mean (±SD) age of onset was 33.3 ± 6.5 (range: 24–42) years for MS and 39.5 ± 8.6 (range: 30–55) years for Parkinson’s disease patients. In all patients, MS was preceded Parkinson’s disease. Parkinson’s disease was developed within mean duration of 6.1 ± 3.4 (range 2–13) years after MS. Focal lesions was shown in six cases, lesions of basal ganglia (BG) in four, lesions of the thalamus in two and lesions of mid-brain in five of cases. In four cases, Parkinsonism occurred before age 40 that is considered as Young-Onset Parkinson’s disease. We reported eight patients with MS and Parkinson’s disease. To the best of our knowledge, 34 cases of Parkinsonism associating with MS are reported so far. Parkinsonism is a movement disorder, defines as deep gray matter disorder which lead to dopamine deficiency in BG. Investigations have shown that MS could affect deep gray matter structures. Demyelinated lesions in MS and consequence axonal loss in BG and/or nigrostriatal pathway may be responsible for Parkinsonism manifestations in such cases.

A 65-year-old man came to our clinic with progressive disequilibrium and gait problem since 6 years. During this period, he had urinary incontinence also.On neurologic examination, he had scanning speech and bidirectional nystagmus. There was hypokinesia in upper and lower limbs and on cerebellar tests finger to nose and heel to shin were impaired (severe dysmetria); he was unable to walk without bilateral support.The brain magnetic resonance imaging (MRI) of the patient showed severe cerebellar and pontine atrophy and a typical hot cross bun sign in pons, which is typical for MSA (Figure 1).Characteristic features of MSA on brain MRI are hyperintensity and thinning of putamen, narrowing and hyperintensity of posterolateral part of putamen, atrophy of brainstem (especially pons) and cross hyperintensity of pons (hot cross bun sign). The cause of hot cross bun sign is degeneration of pontine neurons and pontocerebellar fibers.Conflict of Interests: The authors declare no conflict of interest in this study.

Virchow-Robin spaces are perivascular spaces that surround small arteries and arterioles as they enter the brain parenchyma. They are usually normal findings on MRI of healthy people. Rarely, Virchow-Robin spaces look strikingly enlarged, causing mass effect and unusual cystic conformations that may be misinterpreted as other pathologic processes, such as a cystic neoplasm. Here, we describe a 52-year-old woman in whom brain magnetic resonance imaging (MRI), performed to evaluate Parkinsonism, incidentally found giant Virchow-Robins space or Swiss cheese brain syndrome. In our patient, it seems that the giant Virchow-Robin spaces have been found incidentally and are not associated with the patient’s Parkinsonism symptoms.

A 49 year old woman diagnosed as a cervical cancer patient, after receiving appropriate treatment experienced metastasis in her abdominopelvic cavity. After aggressive management, she was well for a while. However, she developed to a poor condition consisting of urologic, gastroenterological, hematologic and neurologic problems just in a short time. In the course of hospital she presented one sided passive bradykinesia, resting tremor, cogwheel rigidity with controlateral suspicious CT scan of brain. She passed away soon after that.
