Staged reconstruction of large skull defects with soft tissue infection after craniectomy using free flap and cranioplasty with a custom-made titanium mesh constructed by 3D-CT-guided 3D printing technology: Two case reports
Rationale: A craniectomy, which results in a large skull defect, is performed to decrease the intracranial pressure under conditions such as intracranial hemorrhage and ischemic stroke. When the patient's condition is stabilized, autologous cranioplasty using the bone flap previously removed in the craniectomy is performed. Bone flap infection after the autologous cranioplasty is not uncommon and is difficult to treat. After the infection is controlled, cranioplasty is needed to improve the head deformity and neurologic function. Cranioplasty with a titanium mesh can result in aesthetic improvement and a low infection ra...

Discrepancy between perfusion- and diffusion-weighted images in ischemic stroke: A case report
Rationale: With the development of multi-slice computed tomography (CT) technology, perfusion CT angiography (p-CTA) is now widely used for the diagnosis of acute cerebral infarction. Although p-CTA has the advantage of distinguishing between an ischemic penumbra and an infarct core, more research is needed with respect to its clinical use. Patient concerns: A healthy 36-year-old man experienced sudden dizziness while swimming. His dizziness persisted irrespective of the change in position, and then improved during transport. He had no neurological abnormality when he arrived at the emergency room. Diagnoses: CT pe...

A case report on middle cerebral artery aneurysm treated by rapid ventricular pacing: A CARE compliant case report
Rationale: Cerebral aneurysm is a common cause of intracranial hemorrhage, stroke, and death. It is treated with vascular surgeries, such as coil embolism and artery clipping. However, surgery itself is a risk factor that may cause rupture of aneurysm, and leads to irreversible brain damage, and even death. Rapid ventricular pacing (RVP) is a procedure that temporarily lowers blood pressure by increasing heart rate and reducing ventricular filling time. RVP has been widely used to reduce blood vessel tension in many cardiovascular surgeries. Patient concerns: A 46-year-old man came to our hospital with intermittent ri...

Angiography with the 256-multislice spiral computed tomography and its application in evaluating atherosclerotic plaque and cerebral ischemia
Ulceration of carotid arterial plaque is associated with cerebral events. Detection of ulcerated plaques will benefit patient from stroke and other ischemic events. The aim of this study was to evaluate morphology of atherosclerotic plaques in the carotid arteries and to assess its clinical impact in predicting cerebral events. A total of 386 patients were examined with 256-multislice spiral computed tomographic angiography (MSCTA). It was found that 356 of the 386 patients had cerebral ischemic symptoms. Specifically, 35 patients had amaurosis fugax (AmF), 178 had transient ischemic attack (TIA), and 143 had ischemic st...

Preliminary study of time maximum intensity projection computed tomography imaging for the detection of early ischemic change in patient with acute ischemic stroke
This study aimed to assess the accuracy of time maximum intensity projection computed tomography technique (tMIP), which reflects the maximum value for the time phase direction from the dynamic volume data for each projected plane, for detection of EIC, against that of NCCT. Retrospective review of NCCT, cerebral blood volume in CT perfusion (CTP-CBV), and tMIP of 186 lesions from 280 regions evaluated by Alberta Stroke Program Early CT Score (ASPECTS) in 14 patients with acute middle cerebral artery stroke who had undergone whole-brain CTP using 320-row area detector CT was performed. Four radiologists reviewed EIC on NC...

An overlooked cause in a patient with recurrent ischemic stroke: A case report
Rationale: The majority of ischemic strokes are due to cardioembolism, large vessel atherothromboembolism, small vessel occlusive disease, or other unusual mechanisms. In most clinical settings, many strokes without a well-defined etiology requires a thorough diagnostic evaluation, otherwise the underlying cause might be easily overlooked. Here we report on the rare cause of a patient with recurrent stroke. Patient concerns: A 50-year-old female patient had a 4-year history of recurrent acute onset of neurological deficits. Diagnoses: Contrast transcranial Doppler ultrasound detected a typical “curtain” appeara...

A case report of parenchymal hematoma after intravenous thrombolysis in a rivaroxaban-treated patient: Is it a true rivaroxaban hemorrhagic complication?
AbstractRationale:To date, the only treatment approved for acute ischemic strokes is thrombolysis. Whether intravenous thrombolysis may be safe in patients taking direct oral anticoagulants (DOACs) is currently a matter of debate.Patient concerns:A 74-year-old woman, who was on rivaroxaban 20 mg/d for nonvalvular atrial fibrillation, was admitted to our stroke unit with left-sided hemiparesis and aphasia. The onset of neurologic deficits had occurred 5 hours after the last rivaroxaban dose.Diagnosis:An acute ischemic stroke was diagnosed.Interventions:The patient was administered thrombolytic treatment with intravenous r...

Degeneration of paramedian nuclei in the thalamus induces Holmes tremor in a case of artery of Percheron infarction
Abstract Rationale: Holmes’ tremor is an uncommon neurologic disorder following brain insults, and its pathogenesis is undefined. The interruption of the dento-rubro-thalamic tract and secondary deterioration of the nigrostriatal pathway are both required to initiate Holmes’ tremor. We used nuclear medicine imaging tools to analyze a patient with concurrent infarction in different zones of each side of the thalamus. Finding whether the paramedian nuclear groups of the thalamus were injured was a decisive element for developing Holmes’ tremor. Patient concerns: A 36-year-old woman was admitted to our department d...

A multiparameter model predicting in-hospital mortality in malignant cerebral infarction
Abstract: The early identification of patients with large hemisphere infarctions (LHIs) at risk of fatal brain edema may result in better outcomes. A quantitative model using parameters obtained at admission may be a predictor of in-hospital mortality from LHI. This prospective study enrolled all patients with LHI involving>50% of the middle cerebral artery (MCA) admitted to our neurological intensive care unit within 48 hours of symptom onset. Early clinical and radiographic parameters and the baseline CHADS2 score (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke [double weight]) w...
