Multiple sclerosis (MS) is a chronic disorder that affects the central nervous system myelin. However, a few radiological cases have documented an involvement of peripheral cranial nerves, within the subarachnoid space, in MS patients. We report the case of a 36-year-old female with a history of relapsing-remitting (RR) MS who consulted for a subacute complete paralysis of the right III nerve. Magnetic resonance imaging (MRI) examination showed enhancement and thickening of the cisternal right III nerve, in continuity with a linear, mesencephalic, acute demyelinating lesion. Radiological involvement of the cisternal part of III nerve has been reported only once in MS patients. Radiological involvement of the cisternal part of V nerve occurs more frequently, in almost 3% of MS patients. In both situations, the presence of a central demyelinating lesion, in continuity with the enhancement of the peripheral nerve, suggests that peripheral nerve damage is a secondary process, rather than a primary target of demyelination.

Background: Coronavirus disease 2019 (COVID-19) has been associated with many neurological complications affecting the central nervous system. Purpose: Our aim was to describe a case of COVID-19 associated with a probable variant of acute necrotizing encephalopathy (ANE). Results: A 60-year-old man who presented with a 3-day history of dyspnea, fever, and cough tested positive for severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2). Five days following his admission, the patient was intubated secondary to respiratory failure. Following his extubation 16 days later, he was found to have a left-sided weakness. Magnetic resonance imaging (MRI) of the brain showed hemorrhagic rim-enhancing lesions involving the right thalamus, left hippocampus, and left parahippocampal gyrus. These lesions showed decreased relative cerebral blood flow on MR perfusion and restricted on diffusion-weighted imaging. These neuroimaging findings were consistent with ANE. The left-sided weakness gradually improved over the subsequent weeks. Conclusions: We concluded that COVID-19 can be associated with ANE, a condition believed to be the result of an immune-mediated process with activation of the innate immune system. Future studies must address whether biological drugs targeting the pro-inflammatory cytokines could prevent the development of this condition.

Introduction: Facial Palsy (FP) is the most common acute mononeuropathy and consists of a decrease in facial muscle strength due to facial nerve damage. Peripheral FP (PFP) can result from a wide variety of disorders and aetiologies, with Lyme Disease (LD) being considered one of the most common causes of FP. LD is an infectious disease that affects the central nervous system, causing Neuroborreliosis (NB) in 15% of cases. Cranial neuropathy is the most common form of presentation of NB, as uni or bilateral PFP. We describe a case of PFP with hypoacusis and vertigo as the inaugural presentation of neuroborreliosis. Case Report: We present a case report of a 75-year-old female patient, referred to ENT consultation due to a 3-day course of a grade 4 right PFP, moderate right sensorineural hearing loss and right vestibular hypofunction. The patient underwent cranioencephalic Computed Tomography (CT-CE) which excluded a central event and was treated with 2 cycles of oral corticosteroids, without any clinical improvement. A Magnetic Resonance Imaging (MRI) was performed, which showed an abnormal inflammatory uptake of the right facial nerve. An analytical positivity for Borrelia IgM was found and the diagnosis of polyneuropathic NB with involvement of the VII and VIII right cranial pairs was assumed. The patient completed 28 days of doxycycline, with FP and vertigo improvement and normalization of hearing acuity. Discussion/Conclusion: In the presented case, the absence of the classical migratory erythema or painful meningopolyneuritis didn’t exclude the diagnosis of NB. FP associated to signs of other cranial nerves involvement raised the hypothesis of a systemic polyneuropathic disease, which motivated the etiological investigation carried out.

Patient’S History

A 29-year-old Caucasian female diagnosed with multiple sclerosis (MS) for seven years, presented with a history of headaches and a single episode of new onset seizures. Her physical examination was unremarkable and she was placed on anti-seizure medications. A computed tomography (CT) scan showed a right frontal brain lesion causing minimal mass effect (Figure 1). Magnetic resonance imaging (MRI) revealed a large nonenhancing space occupying lesion in the right frontal lobe, in addition to numerous smaller lesions which were characteristic of MS plaques (Figures 2 & 3). The large lesion was causing mass effect with right to left midline shift (Figures 2, 3A & B). Given the patient’s history, the appearance and unusually large size of the frontal lesion, it was unclear whether it was a demyelinating MS plaque, or an intra-axial tumour.

A 51-year-old man is reported who was suffering from an extensive right-sided glossopharyngeal neurinoma (4.6×3.4 cm). The patient was admitted with a history of headache for six to seven years and vomiting for two years accompanied by a progressive hearing loss, tinnitus and dizziness during the last year. Audiometry indicated a perceptive deafness in the whole frequency range up to 70 dB HL, while electronystagmography (ENG) showed a loss of vestibular function of the right side, but there were no signs of a jugular foramen syndrome. Magnetic resonance imaging (MRI) revealed a large tumor portion in the right cerebello-pontine angle with only a small part in the jugular foramen. The neurinoma was completely removed by microsurgery through a suboccipital approach with preservation of nerves VII–XII. The postoperative course was uneventful and normal function of facial and caudal cranial nerves (Nn IX–XII) were proven by electromyography and magnetic stimulation, with exception of a transitory hypesthesia in the palatine region which completely normalized within a few months. The right-sided hearing loss was unchanged, but vertigo improved. In comparison with literature review the lack of temporary or permanent postoperative dysfunctions of caudal cranial nerves as well as of the facial nerve was extraordinary in the reported case.

We report the disease characteristics, diagnosis, and treatment of granulomatous orchitis. A 38-year-old man presented with a history of intermittent swelling, pain, and discomfort in the right testicle of 3 days’ duration. Unenhanced magnetic resonance imaging (MRI) of the testis and scrotum revealed an oval mass in the right testis measuring approximately 17 mm in diameter, with clear borders and a target ring-like appearance from periphery to center. T1-weighted imaging (T1WI) showed uniform low-intensity signals, and T2WI showed mixed high- and low-intensity signals. Diffusion-weighted imaging (DWI) signals were iso-intense, and the outer ring on enhanced scans showed progressive enhancement. We performed radical resection of the right testis under combined spinal–epidural anesthesia. The pathological diagnosis was granulomatous right orchitis. Two months postoperatively, ultrasonography showed no testis and epididymal echo signals in the right scrotum, and no obvious abnormalities; color Doppler blood flow imaging (CDFI) findings were normal. Granulomatous orchitis is rare in clinical practice, and the cause is unknown. The disease involves non-specific inflammation; however, it is currently believed that antibiotics and steroids are ineffective for conservative treatment, and orchiectomy should be actively performed.

History Of Depression

A 27-year-old woman presented to the emergency room after having witnessed generalized tonic clonic seizure while asleep. Birth and development were normal. She had suffered a single febrile seizure at 13 months of age, but had no other seizure risk factors. She was otherwise well except for a history of depression for which she was taking sertraline. Depressive symptoms had been well controlled over the past 3 months, but she had been under increased stress working to finish a doctoral thesis. Neurological examination was normal. Magnetic resonance imaging (MRI) showed modest asymmetry of the hippocampi, slightly smaller on the right, but no abnormal signal and well-preserved laminar anatomy. An electroencephalogram was negative. She was discharged from the emergency room with no treatment. Three weeks later, the patient's boyfriend witnessed an episode of behavioral arrest with lip smacking and swallowing automatisms lasting 45 seconds, after which the patient was confused for 20–30 minutes. The next morning she and her boyfriend kept a previously scheduled appointment with a neurologist.

Background: Dalfampridine extended release (DAL) is a broad-spectrum voltage-gated potassium channel blocker that is indicated in multiple sclerosis to improve the nerve conduction of demyelinated axons. Seizures are a known side effect of DAL, which is contraindicated in patients with a history of epilepsy. Objective: Three cases of multiple sclerosis (MS) with de novo convulsive status epilepticus (CSE) probably related to dalfampridine administration are described. Methods: No patients had a history of seizures or renal impairment. Biological tests were normal. A brain magnetic resonance imaging (MRI) showed diffuse cortical and subcortical atrophy without active inflammatory lesions. Results: All three patients presented with CSE that was attributed to DAL and so was discontinued. Conclusion: These case reports illustrate that, aside from seizures, de novo CSE is a potential complication of MS patients treated with DAL.

Piecemeal Resection

This video illustrates the case of a 52-year-old man with a history of multiple bleeds from a lateral midbrain cerebral cavernous malformation, who presented with sudden-onset headache, gait instability, and left-sided motor and sensory disturbances. This lesion was eccentric to the right side and was located in the dorsolateral brainstem. Therefore, the lesion was approached via a right-sided extreme lateral supracerebellar infratentorial (exSCIT) craniotomy with monitoring of the cranial nerves. This video demonstrates the utility of the exSCIT for resection of dorsolateral brainstem lesions and how this approach gives the surgeon ready access to the supracerebellar space, and cerebellopontine angle cistern. The lateral mesencephalic safe entry zone can be accessed from this approach; it is identified by the intersection of branches of the superior cerebellar artery and the fourth cranial nerve with the vein of the lateral mesencephalic sulcus. The technique of piecemeal resection of the lesion from the brainstem is presented. Careful patient selection and respect for normal anatomy are of paramount importance in obtaining excellent outcomes in operations within or adjacent to the brainstem.The link to the video can be found at: https://youtu.be/aIw-O2Ryleg.

Rosai Dorfman disease is a rare histiocytic disorder. It is also known as Sinus Histiocytosis. It is with massive lymphadenopathy involves an overproduction of a type of white blood cell. The disease is rarely associated with intracranial and intraorbital involvement. Intracranial Rosai-Dorfman can mimic meningioma. Other pathologies also underline its pathologies. Here, we report a nine-year-old boy with a history of proptosis of the right eye and presenting with multiple skull lesions. Histopathological study revealed Sphenopetroclival lesion, which features that of Rosai Dorfman Disease. His MRI scan of the brain was taken, which showed evidence of right optic nerve meningioma with sella and suprasellar extension, causing severe proptosis. The child underwent right frontotemporal craniotomy with petrosectomy and Transylvanian, subtemporal approach to multicompartmental Rosai-Dorfmans lesion. After four months, the patient had a recurrence of the disease on which chemotherapy and steroids were started, which also did not show much response while taking an MRI scan. A corticosteroid is a useful option in the Central Nervous System Rosai Dorfman disease treatment. But this patient showed a negative outcome to the treatment.
