Abstract
BACKGROUND Cerebellar infarcts are encountered commonly in clinical practice; however, they are likely to be misinterpreted. They cannot be adequately evaluated on scales such as the National Institute of Health Stroke Scale (NIHSS), which can have fatal consequences. AIM To evaluate the baseline features, prognosis, and 6-month survival in patients with cerebellar stroke. METHODS A total of 200 patients with cerebellar ischemia were included in the study. Patients were analyzed retrospectively from 10 years of data. Both univariate and multivariate analyses were evaluated. RESULTS Mean age was 68 years old, and men were more frequently affected. The most common symptoms were dysarthria and vertiginous sensations. Ischemic lesions were usually cortical/juxtacortical, multiple, hemispheric, and small (below 1.5 cm). The most commonly affected artery was the medial branch of the posterior inferior cerebellar artery. Cardioembolism was the more frequent etiology. Gait ataxia was associated with a more favorable prognosis and 6-month modified Rankin Scale (mRS) scores (OR: 0.15, 95% CI, P = 0.03). Older age (OR: 1.75, 95%, P = 0.02), female gender (OR: 6.72, 95%, P = 0.02), multiple (OR: 10.92, 95%, P = 0.01) and large lesions (OR: 6.56, 95% CI, P = 0.01), posterior circulation ischemic lesions extra-cerebellum (OR: 8.33, 95% CI, P = 0.01), left ventricular apical hypokinesia or AF (OR: 5.58, 95% CI, P = 0.02), and a high mRS score on admission (OR: 5.21, 95% CI, P < 0.001) was correlated with higher 6-month mRS and a lower survival rates. CONCLUSION The study found that some baseline clinical, neurovascular imaging findings, and the mRS score on admission are useful predictors of cerebellar stroke prognosis and outcome.

Abstract
Cerebellar infarction, a rare category of stroke, is often misdiagnosed but not given much importance in the available literature. Its presentation overlaps with symptoms of other neurologic, cardiovascular, gastrointestinal, and systemic conditions and therefore is nonspecific. Early diagnosis and management of cerebellar strokes are of utmost importance as the lack of a proper diagnosis may increase overall morbidity and mortality. Lack of awareness of the warning signs and symptoms, non-specificity of symptoms, absence of neurological deficits, and imaging discrepancies are some of the factors contributing to misdiagnosis and delayed treatment. If symptomatology is considered, it is found that symptoms of posterior circulation stroke were more frequently misdiagnosed compared to anterior circulation. Nausea and vomiting increased the chance further. Some other rare presentations include gastrointestinal symptoms, isolated vertigo, and symptoms of inner ear disease. Overdependence on radiological investigations often masks the significance of clinical examination. Ischemic stroke may appear normal in the initial 48 hours in the computed tomography scan of the brain or bony artefacts may hide the lesion. Permanent disabling deficits can follow a cerebellar stroke and the complications, which include hydrocephalus, brain stem compression, and gait abnormalities, necessitate prompt identification and management. In this review article, we aim at analysing various case reports of cerebellar infarction, the most common presentations that were under-evaluated, and their outcomes, thereby highlighting the importance of proper diagnosis and reporting of cerebellar infarction in the future. A thorough knowledge of the association between various clinical presentations of cerebellar stroke and its misdiagnosis helps clinicians to be more vigilant about the disease.

Abstract
Cerebellar ischemic stroke (CIS) is a morbid neurological event, with potentially fatal consequences. There is currently no objective standard of care regarding when surgical procedures are required for this entity. We retrospectively reviewed 763 patients with CIS, 247 patients of which had a stroke larger than 1 cm in greatest dimension on cranial imaging. In this subgroup, 11% of patients received ventriculostomy, 12% suboccipital craniectomy, and 9% mechanical endovascular thrombectomy. Various clinical and radiographic variables were examined for relationship to surgical procedures, 30-day mortality rate, and modified Rankin scores. The smallest volume of stroke requiring a surgical procedure was 15.5 mL3 (BrainLab Software). Patients receiving surgical procedures had a higher incidence of multi-territory infarctions, hydrocephalus, cistern compression, 4th ventricular compression, as well as younger age, lower admission GCS, higher admission NIHSS, and higher 30-day mortality/disability. Patients deemed to require surgical procedures for CIS have a higher expected morbidity and mortality than those not requiring surgery. Various clinical and radiographic variables, including stroke volume, can be used to guide selection of patients requiring surgery.

Abstract
BACKGROUND AND PURPOSE Inpatient rehabilitation facilities play an integral role in patient progress post-stroke. Cerebellar hemorrhages are an infrequent type of stroke and are therefore less discussed in the literature; however, inpatient rehabilitation continues to be an integral part of patient recovery. The purpose of this case report is to discuss the physical therapy interventions, challenges, and successes for a complex patient with a large cerebellar hemorrhage with obstructive hydrocephalus. Case Description: The patient is a 32-year-old male admitted to an inpatient rehabilitation facility. Prior to admission, the patient spent 1 month at a local hospital following a complicated recovery status post cerebellar hemorrhage with obstructive hydrocephalus. Interventions: The patient participated in at least 3 hours of combined therapy a day, split into 30- and 60-min sessions, and divided between physical, occupational, and speech therapy. Physical therapy interventions focused on various gait and coordination activities. Outcomes: The patient spent 47 days in an inpatient rehabilitation facility and demonstrated improvements in all aspects of the Functional Independence Measure®. The patient improved from an 18 to a 90 on the total FIM® score, allowing the patient to ultimately be discharged home with family able to provide 24/7 supervision.

Abstract
Background: Cerebellar infarct is a rare condition with very nonspecific clinical features. The aim of this study was to assess the full spectrum of the clinical characteristics, neuroimaging findings and neurofunctional analyses of cerebellar infarction, and the relationship between them. Materials and Methods: Data were collected from 59 patients admitted to our department during an 8-year period. We retrospectively analyzed the relationship between demographic characteristics, clinical symptomatology, etiological factors, functional condition, vascular distribution, frequency of subcortical white matter lesions (WMLs), and concomitant lesion outside the cerebellum in patients with acute cerebellar infarct (ACI) at time of admission. Results: The mean age in our series was 65.2 years, with most being male (57.6%). The posterior inferior cerebellar (PICA) artery was the most commonly affected territory at 62.7%. There was concomitant lesion outside the cerebellum in 45.7%. The main etiology in PICA was cardioembolism. While mean National Institutes of Health Stroke Scale on admission was 2.08 ± 1.67 in study group, modified Rankin Scale (mRS) on admission was detected to be mRS1 (n: 44, 74.5%) and mRS2 (n: 12, 20.3%) most frequently. Fourteen (35%) patients were detected to be in Fazekas stage 0; 11 (27.5%) patients in Fazekas stage 1; 6 (15%) patients in Fazekas stage 2; and 9 (22.5%) patients in Fazekas stage 3. Conclusion: Cerebellar infarct is very heterogeneous. The other cerebral area infarcts which accompany ACI negatively affect neurologic functional scores. Although it is difficult to detect the relationship between WMLs and neurologic functional severity, timely detection of risk factors and their modulation may be associated with prevention and treatability of WMLs, and this may be one of the important points for prevention of stroke-related disability.

Abstract
BACKGROUND In dogs with ischaemic stroke, a very common site of infarction is the cerebellum. The aim of this study was to characterise neurological signs in relation to infarct topography in dogs with suspected cerebellar ischaemic stroke and to report short-term outcome confined to the hospitalisation period. A retrospective multicentre study of dogs with suspected cerebellar ischaemic stroke examined from 2010-2015 at five veterinary referral hospitals was performed. Findings from clinical, neurological, and paraclinical investigations including magnetic resonance imaging were assessed. RESULTS Twenty-three dogs, 13 females and 10 males with a median age of 8 years and 8 months, were included in the study. The Cavalier King Charles Spaniel (n = 9) was a commonly represented breed. All ischaemic strokes were located to the vascular territory of the rostral cerebellar artery including four extensive and 19 limited occlusions. The most prominent neurological deficits were gait abnormalities (ataxia with hypermetria n = 11, ataxia without hypermetria n = 4, non-ambulatory n = 6), head tilt (n = 13), nystagmus (n = 8), decreased menace response (n = 7), postural reaction deficits (n = 7), and proprioceptive deficits (n = 5). Neurological signs appeared irrespective of the infarct being classified as extensive or limited. All dogs survived and were discharged within 1-10 days of hospitalisation. CONCLUSIONS Dogs affected by rostral cerebellar ischaemic stroke typically present with a collection of neurological deficits characterised by ataxia, head tilt, and nystagmus irrespective of the specific cerebellar infarct topography. In dogs with peracute to acute onset of these neurological deficits, cerebellar ischaemic stroke should be considered an important differential diagnosis, and neuroimaging investigations are indicated. Although dogs are often severely compromised at presentation, short-term prognosis is excellent and rapid clinical improvement may be observed within the first week following the ischaemic stroke.

Abstract
AbstractPosttraumatic cerebral infarction is an uncommon cause of morbidity and mortality and many studies have highlighted that trauma needs to considered as causative factor for cerebellar infarction. We present a case of cerebellar infarction in a 35 year old young patient secondary to vertebral fracture involving the vertebral foramen and vertebral artery injury. CT scan cervical spine showed C2-3 fracture on left side with fracture extending into the left vertebral foramen. A CT scan angiogram could not be performed because of poor neurological status. Possibly the infarction was due to left vertebral artery injury. Without surgical intervention prognosis of these patients remain poor. Prognosis of patients with traumatic cerebellar infarction depends on the neurological status of the patient, intrinsic parenchymal damage and more importantly extrinsic compression of the brainstem by the edematous cerebellar hemispheres.
