In this report, we describe rare two pediatric cases that developed oro-mandibular dystonia due to moyamoya disease.

A 7-year-old boy presented with oro-mandibular dystonia and transient weakness of the left extremities, and was diagnosed as moyamoya disease. Another 7-year-old boy developed oro-mandibular dystonia alone and was diagnosed as moyamoya disease. In both, cerebral blood flow (CBF) was markedly decreased in the involved hemispheres, including the basal ganglia and cerebral cortex. They successfully underwent combined bypass surgery and experienced no further attacks of oromandibular dystonia during follow-up periods. CBF almost normalized through surgical collaterals through direct and indirect bypass.

When treating patients with oro-mandibular dystonia, moyamoya disease should be listed as one of the differential diseases. The underlying mechanism of oro-mandibular dystonia in moyamoya disease is still unclear, but persistent cerebral ischemia in the basal ganglia and/or parietal lobe may play a key role to induce this rare symptom.

Cerebellar hemorrhage is rare in children, and its cause is usually vascular disorders such as arteriovenous malformations or hematological disorders.

A previously healthy 10-year-old girl presented with a loss of consciousness following sudden headache and vomiting. A non-contrast brain computed tomography (CT) scan revealed a massive cerebellar hemorrhage with obstructive hydrocephalus; however, subsequent CT angiography (CTA) showed no vascular abnormalities. An emergency craniotomy was performed to evacuate the hematoma, and histological analysis of the specimen obtained from the tissue surrounding the hematoma revealed a pilocytic astrocytoma (PA). Six months after the ictus, her recovery was scored at 2 on the modified Rankin Scale.

PA can be a cause of critical cerebellar hemorrhage. In this case of life-threatening massive hematoma, CTA was useful to exclude a major vascular pathology and to save time.

in the form of skull base osteomyelitis.

A 67-year-old male presented with complaints of earache and hearing deficit for few months. The radiology was suggestive of skull base osteomyelitis and polypoidal soft tissue extending from the middle cranial fossa to the infratemporal fossa. The sample from the targeted area revealed

is an infection exclusively seen in pulmonary infection in patients with CF. We identified its intracranial involvement in a patient for the 1
time in the literature. The serendipitous diagnosis needs evaluation on specific PCR and matrix-assisted laser desorption spectrometry. The treatment with antibiotics provides a definite cure.

We report a rare opportunistic infection with central nervous system involvement which can be cured by accurate diagnosis and appropriate antibiotic treatment.

Cerebellar mutism (CM) is defined as the lack of speech production, despite an intact state of consciousness and cognitive function, that happens secondary to a cerebellar insult. To the best of our knowledge, only five cases have thus far been described in the English literature. In this paper, we report the sixth incidence overall, which is also the first case of a CM associated with penetrating head injury. The relevant literature is reviewed and analyzed, our current knowledge of the neuroanatomical and functional relations is summarized, and potential future research endeavors are indicated.

An 8-year-old girl was transferred to our hospital having had fallen on a rod that penetrated her neck behind the ear. An urgent computed tomography scan of the head revealed a right cerebellar contusion with surrounding edema. L-SelenoMethionine research buy Three days later, she became mute but was still obeying commands. Repeat imaging showed a resolving cerebellar contusion with increased edema and mass effect. By day 9, she had uttered a few words. link2 At 1-month follow-up, the child had regained normal speech.

Posttraumatic CM is a rare and probably underreported condition with only six documented cases to date. link3 Although it may well be on the same spectrum as postoperative CM, further understanding of the exact mechanism, clinical course, and prognosis of this entity is bound to significantly improve the recovery and quality of life of head trauma patients.

Vertebral artery stump syndrome (VASS) develops into recurrent posterior circulation ischemic stroke after ipsilateral vertebral artery (VA) occlusion at its origin.

The patient was a 46-year-old man with the right posterior cerebral artery occlusion. We used a recombinant tissue plasminogen activator (rt-PA) and then performed mechanical thrombectomy using a stent retriever. Angiography revealed left VA occlusion and stagnant flow to the left VA from the right deep cervical artery; therefore, we diagnosed VASS. Within 24 h of the rt-PA injection, the symptoms had dramatically improved, and so we avoided additional antithrombotic agents. Only 13 h later, the patient developed a basilar artery occlusion and died in spite of a repeated mechanical thrombectomy.

Vigilance against early (and sometimes fatal) recurrent stroke induced by VASS is required.

Remote-site extradural hematomas (EDHs) after decompressive-surgeries for traumatic brain injury (TBI) are rarely encountered. Typically, they form contralateral to the injured side, with an overlying fracture. We present a subset which developed EDH immediately after decompressive-hemi-craniectomy for TBI, most without an evidence of fracture, and not limited to contralateral location.

Nine such patients were retrospectively identified. Plausible mechanisms, management issues and outcomes have been discussed.

All nine patients were victims of severe-TBI. Six did not have any skull-fractures. Eight showed hemispheric-injuries while one had bifrontal-contusions. In hemispheric-injuries, midline-shift was at least 8 mm except one with midline-shift of 6 mm. The EDH was straddling the midline in 2 (bifrontal-1, bi-occipital-1), and juxtaposed to the previous craniectomy in 1, apart from a contralateral-bleed in 6; all, except one, needed evacuation. In most patients, venous-source of bleed was identified. All had improved from their preoperative Glasgow coma scale (GCS) at follow-up.

A fracture need not always co-exist in EDH following decompressive craniectomy. However, an extra-caution is suggested in its presence. Given the need for surgical-evacuation in most patients and an inability to assess immediate postoperative-GCS in severely head-injured, a routine postoperative-computed tomography is recommended to avoid overlooking such potentially treatable condition.

Chronic subdural hematoma (cSDH) represents a complex and unpredictable disease, characterized by high morbidity and mortality, especially in elderly patients. Factors affecting the postoperative brain reexpansion along to cSDH recurrence have not been yet adequately investigated. The authors presented the case of a schizophrenic patient affected by trabecular type cSDH that presented a delayed brain reexpansion despite a craniotomy and membranotomy.

A 51-year-old female patient with diagnosis of schizophrenia was admitted to the emergency department with GCS score of 5/15 and right anisocoria. An urgent brain CT revealed a trabecular right cSDH (35 mm in maximum diameter) with recent bleeding. After surgery, a brain CT scan showed a markedly reduced brain reexpansion and pneumocephalus. Nevertheless, postoperative 7-day brain CT documented a progressive brain reexpansion with reduced midline shift.

According to our opinion, anatomopathological alterations in schizophrenia reduce normal brain compliance and increasing elastance, thus modifying the normal timing of reexpansion after cSDH drainage, also after craniotomy and membranotomy. Although postoperative pneumocephalus is a well-known cause of hindered reexpansion, this could be due to anatomical alterations in schizophrenia. Such factors must be considered in the preoperative planning but mostly in the postoperative management.

Ependymoma is a slowly growing benign neoplasm that constitutes 3-9% of all neuroepithelial spinal cord tumors.[3,4] They rarely involve the cervicomedullary junction where they both compress the distal brainstem and upper cervical cord. Due to the critical contiguous structures, gross total resection of these lesions may result in significant morbidity/mortality.[1,2] Utilizing intraoperative neuromonitoring can help limit the risks of removing these lesions. Not when considering the risk/complications of partial versus total resection, the surgeon should keep in mind that they are benign slow growing tumors with relatively good long-term survivals following partial removals. This surgical video shows the surgical strategy and management of a giant cervicomedullary ependymoma performed in a 23-year-old female.

A 23-year-old female presented with cervical pain and quadriparesis of 1-year's duration. The MR with/without gadolinium showed a large intradural, intramedullary cervical spinal cord tumor that severely expanded the spinal cord.
