The aneurysm arising from the posterior cerebral artery is relatively uncommon, and has been reported in 0.7- 2.2% of whole cerebral aneurysm. Moreover, only a few cases of the giant aneurysm over 2.5cm in diameter arising from the distal portion of the posterior cerebral artery have been reported. Neurologic complications may occur after surgical treatment of this aneurysm due to difficult surgical approach and neurovascular complexity around the brain stem. Authors experienced a case of the thrombosed giant aneurysm with approximately 2.7cm in diameter arising from the P2 segment of the left posterior cerebral artery. Complete removal of the thrombus in the aneurysmal sac and direct neck clipping was performed via left subtemporal approach.

Bullet injuries to the spine may cause injury to the anatomical structures with or without neurologic deterioration. Most bullet injuries are acute, resulting from direct injury. However, in rare cases, delayed injury may occur, resulting in claudication. We report a case of intradural bullet at the L3-4 level with radiculopathy in a 30-year-old male. After surgical removal, radicular and claudicating pain were improved significantly, and motor power of the right leg also improved. We report the case of intradural bullet, which resulted in delayed radiculopathy.

Spinal infection is an inflammatory process around the vertebral body, and it can extend to the epidural space, posterior elements and paravertebral soft tissues. Infectious spondylitis is a rare infectious disorder, which is often associated with significant neurologic deficits and mortality. When an extensive soft tissue defect is accompanied by infectious spondylitis, effective infection control and proper coverage of soft tissue are directly connected to successful outcomes. However, it is not simple to choose the appropriate treatment methods for infectious spondylitis accompanied by a soft tissue defect. Herein, we report a case of severe infectious spondylitis that was accompanied by an extensive soft tissue defect which was closed with a reverse latissimus muscle flap after traumatic spinal epidural hemorrhage.

Parkinsonism secondary to intracranial mass lesions usually results from compression or distortion of the basal ganglia. Secondary parkinsonism due to midbrain infiltration or compression is rare and generally associated with other neurologic signs caused by pyramidal tract and/or cranial nerve involvement. We report a case of 30-year-old woman in whom mild parkinsonism was the major clinical manifestation of an astrocytoma in the anterior third ventricle and hypothalamus. She underwent surgical resection, ventriculoperitoneal shunt and radiation therapy. All symptoms of parkinsonism were completely recovered 3 months after the treatment. Brain tumors can be manifested only by the symptoms of parkinsonism. This case emphasizes the significance of neuroimaging in the evaluation of parkinsonism.

Spontaneous spinal epidural hematoma (SSEH) is rare in children. especially in infants, in whom only 12 cases have been reported. Because of the nonspecificity of presenting symptoms in children, the diagnosis may be delayed. We report herein a case of SSEH in a 20-month-old girl who initially presented with neck pain, and developed lower extremity motor weakness and symptoms of neurogenic bladder 2 weeks prior to admission. The magnetic resonance imaging showed an epidural mass lesion extending from C7 to T4, and the spinal cord was severely compressed by the mass. After emergency decompressive surgery the neurologic function was improved immediately. Two months after surgery, the neurological status was normal with achievement of spontaneous voiding. We suggest that surgical intervention can provide excellent prognosis in case of SSEH in infants, even if surgery delayed.

Penetrating cerebral injuries caused by foreign bodies occur rarely due to the substantial mechanical protection offered by the skull. Throughout most of history, the brain, residing in a "closed box" of bone, has not been vulnerable to external aggression. Recently, we encountered a serious penetrating craniocerebral injury caused by a nail gun. Total excision of the offending nail via emergency craniotomy was performed, but the patient's neurologic status was not improved in spite of aggressive rehabilitative treatment. Here, we report on this troublesome case in light of a review of the relevant literature.

Parkinson's disease (PD) patients frequently have several spinal deformities leading to postural instabilities including camptocormia, myopathy-induced postural deformity, Pisa syndrome, and progressive degeneration, all of which adversely affect daily life activities. To improve these postural deformities and relieve the related neurologic symptoms, patients often undergo spinal instrumentation surgery. Due to progressive degenerative changes related to PD itself and other complicating factors, patients and surgeons are faced with instrument failure-related complications, which can ultimately result in multiple revision surgeries yielding various postoperative complications and morbidities. Here, we report a representative case of a 70-year-old PD patient with flat back syndrome who had undergone several revision surgeries, including anterior and posterior decompression and fusion for a lumbosacral spinal deformity. The patient ultimately benefitted from a relatively short segment fixation and corrective fusion surgery.

The immature neonatal brain is susceptible to the development of seizures. Seizures occur in 1% to 5% of infants during the neonatal period. Neonatal seizures are most commonly associated with serious acute illnesses, such as hypoxic-ischemic encephalopathy, birth trauma, metabolic disturbances, or infections. Thus, newborn infants with seizures are at risk for neonatal death and survivors are at risk for neurologic impairment, developmental delay, and subsequent epilepsy. Experimental data have also raised concerns about the potential adverse effects of the currently used anticonvulsants in neonates on brain development. Therefore, in the management of neonatal seizures, confirmatory diagnosis and optimal, but shorter, duration of anticonvulsant therapy is essential. Nevertheless, there has been substantial progress in understanding the developmental mechanisms that influence seizure generation and responsiveness to anticonvulsants. The currently used therapies have limited efficacy and the treatment of neonatal seizures has not significantly changed in the past several decades, This review includes an overview of current approaches to the treatment of neonatal seizures.

To validate the technique of the single Heartstring aortotomy for multiple off-pump venous bypass grafts (described in 2015), the results of a 38-month follow-up study of 18 patients, including high-risk patients, are presented. No early deaths or cardiac or cerebral complications occurred. During the follow-up period, 2 patients died of non-cardiac causes, and 3 developed coronary ischemia. Ischemia occurred due to late graft occlusion in 2 patients, both of whom had normal postoperative courses and correct graft flow. The presence of acute symptoms 24 months after surgery in these patients indicated that technical graft failure was unlikely. This safe technique combines the advantages of simple and reproducible revascularization, the off-pump approach, and minimal aortic manipulation.

Trigeminal neuralgia (TN) is generally characterized by lancinating, unilateral, paroxysmal pain occurring in the distribution of the fifth cranial nerve. TN is diagnosed clinically based on the typical patient history, negative findings in a neurologic examination, and the response to medication. Idiopathic TN is the most common type, but TN can result from vascular malformation, compression, trauma, neoplasm, multiple sclerosis, or inflammation. We report a TN case diagnosed as recurrent trigeminal neuritis of the maxillary branch confirmed by magnetic resonance imaging.
