Background: Cerebellar mutism (CM) is a neurological condition characterized by lack of speech due to cerebellar lesions. Interruption of the bilateral dentatothalamocortical (DTC) pathways at midline structure seems the principal cause of CM but not fully understood. We described a rare case of CM due to heterochronic bilateral cerebellar hemorrhages. Case Description: An 87-year-old woman presented with depression of alertness after sudden vomiting. Neurologically, mild dysmetria and mutism were observed. The head computed tomography (CT) showed both a fresh right cerebellar hemorrhage and an obsolete left one. The patient was diagnosed as CM since both the thalamus and the supplementary motor area were bilaterally intact on both CT and magnetic resonance imaging. Medical treatment and rehabilitation improved her ataxia and ambulation. She became cognitively alert and could communicate by nodding, shaking her head, or facial expression. However, her mutism did not change at 4 months after the stroke. Conclusion: There are few reports on CM due to direct injuries to the bilateral dentate nuclei. Since our case did not show any injury other than bilateral dentate nuclei, this report can support the hypothesis that the interruptions of the bilateral DTC are the cause of CM.

Background: Central nervous system conditions may affect every aspect of female reproduction from fertility to lactation. The objective of this study was to examine the performance of computed tomography and magnetic resonance imaging in the diagnosis of maternal neurologic disorders and to examine the outcome of pregnancies complicated by abnormal neurologic imaging.Methods: Retrospective observational study of 20 parturients presenting with severe neurologic symptoms (January 2006 to January 2016).Results: Abnormal neuro-radiological findings were found. Only 10% of the computed tomography-scans were normal. Both magnetic resonance imaging and computed tomography that were performed in all cases showed cerebral edema (90%) with different degrees, thereby cerebral edema was the predominant lesion. Pertaining to its localization, 65% were localized in the parietal or occipital area, 10% in the paraventricular area, and 10% were diffused. Also, 35% showed intracerebral hemorrhage and 10% showed cerebellar hemorrhage. The incidence of neurological disorders in pregnancy and puerperium was high. Epilepsy and headache were the most common primary and secondary neurological disorders.Conclusions: The role of neuroimaging in diagnosing neurological disorders is crucial for prevention of severe complications.

ABSTRACT Cavernous hemangioma is a rare tumor of the adult larynx. These hemangiomas are confined to the larynx and generally asymptomatic. We present a rare case of a huge cavernous hemangioma in a 22-year-old patient who presented with stridor and a huge swelling in the neck, of acute onset. Detailed evaluation including 70° Hopkins laryngoscopy, contrastenhanced computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed a vascular malformation with both intra- and extralaryngeal components. The typical findings of hemangioma with its management are highlighted in this article. Postoperatively, patient's voice improved and the stridor was relieved.

The artery of Percheron is a solitary trunk representing an uncommon anatomic variant that provides bilateral arterial supply to the paramedian thalami and the rostral midbrain. Occlusion of this artery results in bilateral thalamic and mesencephalic infarctions. The clinical diagnosis is difficult because the complex anatomy causes large clinical variability. We report a case of a comatose patient with normal early head-computed tomography and magnetic resonance imaging. A bilateral paramedian thalamic infarct due to an occlusion of the artery of Percheron was revealed two days later by a new head computed tomography. To our knowledge, this is the first report in the literature of a symptomatic patient presenting an acute Percheron stroke with normal early brain magnetic resonance imaging. Our case indicates that a normal initial magnetic resonance imaging cannot formally eliminate the diagnosis of acute stroke of the artery of Percheron. We discuss the causes of noncontributive brain magnetic resonance imaging at the onset of this acute Percheron stroke and the alternative diagnosis and therapy methods.

A rare case of a multicystic acoustic neuroma is reported. At computed tomography (CT) and magnetic resonance imaging (MRI) the tumor was found to cause hydrocephalus, and displacement of the brainstem. The multicystic character was revealed on CT, while MRI only showed the mass lesion and the common signal intensities for an acoustic neuroma. The differential diagnosis of a multicystic lesion in the cerebellopontine angle is discussed.

Hemangiomas rarely occur in the retropharyngeal space with only several cases reported in the current literature. This article reports the hemangiomas of retropharyngeal space. A 55-year-old woman was referred to our institution for dysphagia. Computed tomography and magnetic resonance imaging of the neck and spine revealed a large, well-circumscribed, dense mass that extended from the retropharyngeal space to the sides of the neck. Patient underwent direct excision of the lesion. Complete regression of symptoms was observed after surgery, with no lesions found on routine 24-month follow-up. Although hemangiomas are relatively common in the head and neck, those that originate in the retropharyngeal space are very rarely observed. These benign tumors have the potential to compress adjacent tissues or organs and thereby produce associated symptoms like dysphagia and dyspnea. We present the reported case of larger hemangiomas of the retropharyngeal space and detail their management.

Post Procedure

Background: Sellar cysts are common in neurosurgery. Around 90% of these are diagnosed as pituitary adenomas. The other 10% are nonadenomatous, inflammatory, infective, metastatic, or cystic in nature. Some rare cysts include dermoid, epidermoid, colloid, and arachnoid. They all have different histological features. The case we present demonstrates a unique cyst with features that are not previously documented. Case Description: A 60-year-old female presented to the neurosurgical department complaining of blurring of vision and severe headache for more than ½ year. Imaging was done which revealed a bony erosive lesion in the region of sella. Magnetic resonance imaging with contrast showed high signals with no contrast enhancement. A clear diagnosis could not be made based on radiology. Surgery was done and sample was sent for histopathology. Based on histopathological report findings, a diagnosis of benign atypical sellar cyst was made. Post procedure, the patient recovered and was discharged. Conclusion: Sellar cysts present similarly. They are differentiated based on their histological features. The sellar cyst we encountered had features different from the ones already described in the literature.
