✓ Primary meningeal osteosarcomas are rare tumors, with only 19 reported cases in the literature; only 4 of these, including the present case, are in pediatric patients. In this report, the authors present the case of an 8-year-old boy with a history of generalized tonic–clonic seizures who was found to harbor a meningeal osteosarcoma within the sylvian fissure. Initial working diagnoses included meningioma and glioma. After tumor enlargement and progressive symptoms, the patient underwent a large frontotemporal craniotomy and complete resection of the lesion, which recurred 6 and 12 months after the initial surgery and was surgically treated after each recurrence. The rarity of primary meningeal osteosarcomas can make their diagnosis difficult, and histopathological evaluation is mandatory for diagnosis. Because of their fast progression, they must be treated aggressively by means of surgery, chemotherapy, and radiotherapy.

Background: Acute flaccid myelitis (AFM) is a condition which causes acute paralysis in pediatric patients. Although awareness of AFM is increasing, the pathophysiology and full spectrum of clinical, biochemical, and radiographic features remain to be fully elucidated. Methods: We report a 5 year-old, previously healthy, male patient who presented with acute right upper extremity weakness following a two day history of fever, cough, and fatigue. The patient underwent extensive inflammatory and infectious workup in addition to MRI imaging of the brain, spinal cord, and bilateral brachial plexuses. Results: Infectious and inflammatory workup did not identify a causative agent. The patient was seen to have bilateral asymmetric (R>L) thickening and enhancement of the anterior horn cells of his cervical (C3-C7) spine, consistent with the spinal grey matter lesions previously described in patients with AFM. Enhancement of the corresponding anterior nerve rootlets and bilateral brachial plexuses was also seen. Conclusions: Patients with acute flaccid myelitis may demonstrate grey matter enhancement extending beyond the spinal cord to the peripheral nerves and plexuses, a radiographic finding which has not previously been published.

We report a case of a 77-year-old woman who presented to the Emergency Room with a three-day history of oral lesions and jaw tightness. Her physical examination was remarkable for the presence of trismus and white ulcers on the visible portion of the tongue. CT head and neck was unremarkable, and she was discharged with empiric treatment for oral candidiasis. She returned two days later with worsening symptoms and subsequently developed tonic-clonic seizures. MRI of the brain and temporomandibular joints were noncontributory. Psychiatry was consulted, and the patient was prescribed olanzapine and mirtazapine for suspected depression with somatization symptoms. She continued to deteriorate despite therapy and developed right lid ptosis and ophthalmoparesis, which led to a presumptive diagnosis of cephalic tetanus. On the 14th day of illness, tetanus immune globulin, metronidazole, and tetanus toxoid vaccine were administered. Despite treatment, the patient died after 24 days of hospitalization. This case illustrates the importance of early recognition of tetanus since successful treatment depends on timely administration of immune globulin.

Background: Squamous cell carcinoma (SCC) is the most common form of nonmelanoma skin cancer after basal cell carcinoma. Simple excision can be the treatment at early stages of diagnosis. However, at late stages, treatment is more complex due to extension to the skull and the dura. In extremely rare cases, it can invade the brain making it a challenging situation for treatment. Case Description: We present the case of a 54-year-old man with a history of cutaneous SCC who presented an invasive left frontal recurrence with brain invasion 19 years after initial surgery. The patient underwent surgery which consisted in tumor removal and bone and skin reconstruction. Immediate and late outcomes were favorable. Conclusion: Multidisciplinary treatment for SCC diagnosed in advanced stages is the best way to obtain encouraging results. Although significant advancements have been made, further study is needed for cases with advanced disease.

OBJECTIVESmall lesions at the depth of the sulcus, such as with bottom-of-sulcus focal cortical dysplasia, are not visible from the surface of the brain and can therefore be technically challenging to resect. In this technical note, the authors describe their method of using depth electrodes as landmarks for the subsequent resection of these exacting lesions.METHODSA retrospective review was performed on pediatric patients who had undergone invasive electroencephalography with depth electrodes that were subsequently used as guides for resection in the period between July 2015 and June 2017.RESULTSTen patients (3–15 years old) met the criteria for this study. At the same time as invasive subdural grid and/or strip insertion, between 2 and 4 depth electrodes were placed using a hand-held frameless neuronavigation technique. Of the total 28 depth electrodes inserted, all were found within the targeted locations on postoperative imaging. There was 1 patient in whom an asymptomatic subarachnoid hemorrhage was demonstrated on postprocedural imaging. Depth electrodes aided in target identification in all 10 cases.CONCLUSIONSDepth electrodes placed at the time of invasive intracranial electrode implantation can be used to help localize, target, and resect primary zones of epileptogenesis caused by bottom-of-sulcus lesions.

Moyamoya is an uncommon disease that presents with stenoocclusion of the major vasculature at the base of the brain and associated collateral vessel formation. Many pediatric patients with moyamoya present with transient ischemic attacks or complete occlusions. The authors report the case of a 9-year-old girl who presented with posterior fossa hemorrhage and was treated with an emergency suboccipital craniotomy for evacuation. After emergency surgery, an angiogram was performed, and the patient was diagnosed with moyamoya disease. Six months later, the patient was treated for moyamoya using direct and indirect revascularization; after surgery there was excellent vascularization in both regions of the bypass and no further progression of moyamoya changes. This case illustrates a rare example of intracerebral hemorrhage associated with moyamoya changes in the posterior vascularization in a pediatric patient and subsequent use of direct and indirect revascularization to reduce the risk of future hemorrhage and moyamoya progression.

A 7-month-old, spayed female, domestic longhair cat with L-2-hydroxyglutaric aciduria (L-2-HGA) was investigated. The aim of this study was to investigate the clinical signs, metabolic changes and underlying genetic defect. The owner of the cat reported a 4-month history of multiple paroxysmal seizure-like episodes, characterized by running around the house, often in circles, with abnormal behavior, bumping into obstacles, salivating and often urinating. The episodes were followed by a period of disorientation and inappetence. Neurological examination revealed an absent bilateral menace response. Routine blood work revealed mild microcytic anemia but biochemistry, ammonia, lactate and pre- and post-prandial bile acids were unremarkable. MRI of the brain identified multifocal, bilaterally symmetrical and T2-weighted hyperintensities within the prosencephalon, mesencephalon and metencephalon, primarily affecting the grey matter. Urinary organic acids identified highly increased levels of L-2-hydroxyglutaric acid. The cat was treated with the anticonvulsants levetiracetam and phenobarbitone and has been seizure-free for 16 months. We sequenced the genome of the affected cat and compared the data to 48 control genomes. L2HGDH, coding for L-2-hydroxyglutarate dehydrogenase, was investigated as the top functional candidate gene. This search revealed a single private protein-changing variant in the affected cat. The identified homozygous variant, XM_023255678.1:c.1301A>G, is predicted to result in an amino acid change in the L2HGDH protein, XP_023111446.1:p.His434Arg. The available clinical and biochemical data together with current knowledge about L2HGDH variants and their functional impact in humans and dogs allow us to classify the p.His434Arg variant as a causative variant for the observed neurological signs in this cat.

<b><i>Introduction:</i></b> Biological drugs are currently used for the treatment of chronic inflammatory, autoimmune, and neoplastic diseases. With their expanding indication spectrum and increasing use, hypersensitivity reactions to these drugs are also becoming more frequent. The present study aimed to report the incidence and the features of such reactions in pediatric patients using biologicals for the treatment of various diseases. <b><i>Methods:</i></b> The medical records of pediatric patients treated with biological agents between October 1, 2011 and August 31, 2019 were reviewed and adverse reactions were evaluated retrospectively. <b><i>Results:</i></b> During the study period, 211 patients (116 boys, 55%) used 21 different biological drugs for the treatment of various diseases. Their median age at the time of the first treatment was 139.9 (IQR: 92.2–187.8) months. Hematologic-oncologic diseases were the most common indication for biological therapy (97/211; 46.0%), followed by rheumatologic diseases (82/211; 38.9%). Of the 211 patients, 14 (6.64%) experienced reactions to biological drugs. The most common culprit agent was rituximab (57.1%). Most of the patients (85.7%) had a history of reactions either during the infusion or within 1 h after taking the drug. Five patients underwent desensitization to the culprit drug, while 7 other patients continued treatment with a reduced dose/infusion rate or premedication. Also 1 patient continued to take the drug without any additional treatment. <b><i>Conclusion:</i></b> It was reported that 6.64% of the patients who received biologic drug therapy for various reasons in our hospital had hypersensitivity. The most common culprit agent was rituximab, and most of the reactions were immediate reactions.

Differential diagnosis of globus sensation in an otherwise asymptomatic patient should include hypopharyngeal fibrovascular polyp to avoid potentially fatal complications like airway compromise following regurgitation. We present a case of a 74-year-old man with a 13-cm long hypopharyngeal fibrovascular polyp with 9 months history of globus sensation. A narrow stalk of the giant polyp allowed endoscopic removal and complete resection with the CO2 laser. Histopathological examination was conclusive for the fibrovascular polyp.
