: This study aimed to present a case of a clinically isolated syndrome (CIS) with a reported tumefactive demyelinating lesion (TDLs) in the cord. The patient was a 25-year-old woman who referred to MS Clinic complaining of walking impairment and a blurred vision in the right eye. In the magnetic resonance imaging (MRI) of the brain, there were several periventricular plaques, a significant portion of which had enhanced, but none of the lesions was tumefactive. In the cervical MRI, however, several tumefactive plaques appeared with a clear enhancement and expansion, which was central-based in the axial view. Concerning the involvement of the cervical cord, further examinations were conducted of anti-aquaporin and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies, which were negative. The patient was treated with 1g methylprednisolone daily injection for five days; her symptoms recovered completely. Then, due to the extent of the involvement, rituximab was prescribed for her. Unlike the TDLs of the brain, little attention has been paid to these lesions in the cord. Here, firstly a case of CIS with a tumefactive lesion reported in the cord is investigated, and then, by examining similar cases, we try to find a definition for cord TDLs.

We present a case of an immunocompetent patient who developed Aspergillus meningitis, subsequent to discitis, presumed to be from an epidural steroid injection. Magnetic resonance imaging (MRI) of the lumbar spine confirmed the diagnosis of discitis. Fluoroscopic-guided aspiration of the disc showed growth of Aspergillus fumigatus. MRI of the brain revealed involvement of the right third cranial nerve. Repeat MRIs demonstrated multiple leptomeningeal masses consistent with granulomatous meningitis. Meningitis is a rare complication of discitis, discogram, or epidural steroid injection. Aspergillus usually only infects immunocompromised patients, but rarely can affect immunocompetent patients.

AbstractA 79-year-old patient was admitted to the emergency room with transitory monoparesis in the left hand and dysphasia. The brain computed tomography (CT) and magnetic resonance imaging (MRI) showed a spontaneous right convexity subarachnoid hemorrhage (cSAH). Digital subtraction angiography (DSA) confirmed an asymptomatic occlusion of the right internal carotid artery (ICA) . Cases related to stenosis have already been described, but there is no similar report of a case related to occlusion, even though the pathophysiology of both entities is similar. Atraumatic SAH has been associated with intracranial and extracranial artery stenosis.

This paper describes an unusual clinically isolated syndrome of inflammatory demyelination that was characterized by a right VI nerve palsy and right internuclear ophthalmoparesis (INO), along with an unusual form of dissociated nystagmus. Magnetic resonance imaging (MRI) revealed an isolated lesion within the right dorsomediolateral pontine tegmentum. Four years later, the subject developed a partial sensory transverse myelitis, confirming clinically definite multiple sclerosis (MS). This paper extends the range of isolated syndromes associated with MS.

A 40-year-old right-handed man sought care for right hand numbness, right-sided facial numbness, and diplopia progressing to maximal severity over 10 days. At his worst he was unable to write. His symptoms remained maximal for 4 weeks. He was hospitalized and treated with 5 days of intravenous methylprednisolone. He improved to approximately 95% of normal over 4 weeks. He had residual mild right-sided facial and right leg numbness. Antibodies to JC polyoma virus and varicella-zoster virus were positive, which indicated prior exposure to these viruses. Total 25-hydroxyvitamin D level was low at 8.2 ng/mL. Optical coherence tomography findings were normal. Magnetic resonance imaging of the brain performed 3 months after the onset of symptoms demonstrated a T2-hyperintense lesion in the left midbrain peduncle extending into the upper pons, without gadolinium enhancement. A small area of T2 hyperintensity was seen in the right frontal deep white matter. Follow-up brain magnetic resonance imaging showed almost complete resolution of the left midbrain peduncle lesion with persistence of the right frontal deep white matter lesion. Spinal fluid analysis showed 1 white blood cell/µL with 95% lymphocytes, protein 35 mg/dL, 0 unique oligoclonal bands, and normal immunoglobulin G index (0.54). A diagnosis of clinically isolated syndrome-first episode of multiple sclerosis was made. After detailed discussion with the patient, he elected to commence disease-modifying therapy with fingolimod. He underwent routine monitoring with magnetic resonance imaging of the brain and cervical and thoracic spine on an annual basis, without any further relapses at 5-year follow-up. Patients with typical demyelinating syndromes may not always fulfill the diagnostic criteria for multiple sclerosis. After careful exclusion of other mimicking conditions, most notably aquaporin-4-immunoglobulin G– and myelin oligodendrocyte glycoprotein-immunoglobulin G–associated disease, a diagnosis of clinically isolated syndrome may be made.

A 13-month-old, neutered, male Golden retriever presented with seizures and progressive depression. Clinical and neurological assessment was consistent with severe intracranial disease. The neurological condition progressively deteriorated and magnetic resonance imaging (MRI) revealed the presence of a large, contrast-enhancing, space-occupying mass in the right cerebral hemisphere. Therapy with corticosteroids, mannitol and furosemide ameliorated the signs of depression and ataxia, but the owner elected euthanasia after 1 week. Post mortem examination of the brain confirmed the presence of a large haemorrhagic lesion in the right olfactory lobe, the histopathological appearance of which was consistent with cerebral cavernous haemangioma. This is the 1st case describing the MRI appearance of a cavernous haemangioma of the cerebrum in the veterinary literature.

ABSTRACTHemifacial Spasm (HS) occurs idiopathically or secondary to the lesions compressing the root exit zone of the facial nerve symptomatically. Symptomatic HS is generally due to vascular compression. We report on a 23-year-old male with right sided HS for a month. Magnetic resonance imaging (MRI) of the brain revealed a well-demarcated epidermoid cyst in the right cerebellopontine cistern. It was hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging without contrast enhancement, hyperintense on DWI, and slightly hypointense on ADC relative to the brain. Although it caused shifting of the pons and medulla to the left side and compression of the right cerebellar peduncles and fourth ventricle, the sole symptom of the patient was HS. Clinicians are advised to request MRI/scan for brainstem lesions from the patients with HS. Epidermoid cysts in cerebellopontine cistern may present with HS as the sole symptom.

This paper forms part two of a review of the neurobiology of developmental dyslexia (DD) and here the focus is on magnetic resonance imaging (MRI)of the corpus callosum (CC) of dyslexic and non-dyslexic subjects. The CC is a bundle of nerve fibres connecting the left and the right hemisphere of the brain. Due to the role of this structure in inter-hemispheric transfer and integration between the hemispheres, the CC is significant in the search for the neurobiological basis of DD.

A 61-year-old Caucasian male with severe plaque psoriasis without joint involvement was initiated on adalimumab therapy. Shortly thereafter he presented to the emergency room with acute loss of vision in the right eye. A comprehensive systemic workup was instituted which included magnetic resonance imaging (MRI) with and without gadolinium of the brain and orbits. MRI revealed findings that were consistent with CNS demyelination and retrobulbar optic neuritis. Immediate cessation of adalimumab was instituted without any other systemic therapy. Complete return of vision occurred within 6 weeks. No additional psoriatic or neurologic treatment was instituted, and the patient has remained stable now for 14 months.

AbstractThe computed tomography (CT) scan of a 19-year-old man who died from an occipito-frontal gunshot wound presented an impressive radiating fracture line where the entire sagittal suture burst due to the high intracranial pressure that arose from a near-contact shot from a 9 mm bullet fired from a Glock 17 pistol. Photorealistic depictions of the radiating fracture lines along the cranial bones were created using three-dimensional reconstruction methods, such as the novel cinematic rendering technique that simulates the propagation and interaction of light when it passes through volumetric data. Since the brain had collapsed, depiction of soft tissue was insufficient on CT images. An additional magnetic resonance imaging (MRI) examination was performed, which enabled the diagnostic assessment of cerebral injuries.
