Torticollis is an usual symptom that can be the result of various disorders, such as sternocleidomastoid
muscle pathology, bony abnormalities of the cervical spine, disorders of the central or peripheral
nervous system, various ocular diseases, and brain tumors, especially in children. A 12-month-old
male visited our hospital because of torticollis. He was normal on systemic examination, with no
neurological abnormality, and his cervical spine CT was also normal. About 4 weeks later, he revisited
the emergency department due to vomiting with altered mental status, and was diagnosed with a
cerebellar tumor with hemorrhage. Although torticollis is known to be an important sign of a posterior
fossa tumor, associated neurological or ocular symptoms are usually present. We report here a patient
with posterior fossa tumor where torticollis was the only initial presenting symptom.

The first-line imaging modality used to detect subarachnoid hemorrhage (SAH) is a non-contrast computed tomography (CT) scan. Although a CT scan shows great sensitivity for diagnosis of SAH, especially in the hyper-acute and acute stages, it sometimes shows negative results despite typical symptoms. It is thought that the small amount of blood causing the hemorrage and the delay time of the CT scans were the causes of the negative results. Two patients presented to us with SAH, but initial CT scans were negative. We diagnosed the SAH of these patients using magnetic resonance images.

Objectives: White matter hyperintensities are known to influence dementia in Alzheimer’s disease.
Genetic components are suggested as putative risk factors for vascular pathology and cognitive
decline. This study aimed to determine whether there is an association between candidate genetic
polymorphisms and the severity of white matter hyperintensities in patients with Alzheimer’s disease.
Methods: Seventy-five patients diagnosed with Alzheimer’s disease underwent genetic tests for specific
alleles of apolipoprotein E, angiotensin-converting enzyme, and methylenetetrahydrofolate reductase.
All patients underwent brain magnetic resonance imaging scans and neuropsychological tests. The
severity of white matter hyperintensities was semiquantified using the CREDOS rating scale, and
patients were divided into three groups according to their rating. Results:The severity of white matter
hyperintensities was related to age and hypertension. However, none of the gene polymorphisms we
tested was found to be associated with the severity of white matter hyperintensities.
Conclusion:The genetic polymorphisms found in apolipoprotein E, angiotensin-converting enzyme
and methylenetetrahydrofolate reductase did not contribute to white matter hyperintensities in
Alzheimer’s disease.Only age and hypertension factors were found to be contributory to white matter
hyperintensities.

8.Incidentally Discovered a Self-Inflicted a Nail in the Brain of Schizophrenia Patient.

The self-infliction of foreign bodies into the brain represents rare a clinical phenomenon that has been reported primarily in cases involving accidents and suicide attempts. However, various motivations for self-injurious behaviors as well as suicide attempts have been reported, especially in patients with psychotic illnesses. A 47-year-old man with a history of schizophrenia presented to our hospital due to the presence of a nail on his plain skull X-ray. He diagnosed paranoid type of schizophrenia about 17 years earlier, and his psychiatric symptoms were well controlled by medication. Interestingly, he was not aware of the presence of the nail in his brain and showed no neurological deficits. In the course of detailed history taking, we discovered that the nail was driven into his brain during a hallucinatory experience that had occurred more than 10 years earlier. Because we believed that removing the nail from his brain would be more dangerous than maintaining the status quo, the nail was not removed. This is a very rare case of a self-inflicted injury involving inserting a nail into the brain under the influence of hallucinations. The absence of adverse effects or neurological symptoms/signs related to the presence of a foreign metallic body in the brain for over 10 years is exceptional.

9.A Case of Broncho-Paraspinal Fistula Induced by Metallic Devices: Delayed Complication of Thoracic Spinal Surgery.

We present a case report of a 45-year-old woman with spontaneous pneumocephalus accompanied by pneumorrhachis of the thoracic spine, which is a very rare condition generally associated with trauma and thoracic or spinal surgery. The patient had undergone an operation about 10 years earlier to treat a giant cell tumor of the thoracic spine. During the operation, a metallic device was installed, which destroyed the bronchus and caused the formation of a broncho-paraspinal fistula. This is the suspected cause of her pneumocephalus and pneumorrhachis. To our knowledge, this is a very rare case of pneumocephalus accompanied by pneumorrhachis induced by metallic device, and when considering the length of time after surgery these complications presented are also exceptional.

10.Serial Magnetic Resonance Images of a Right Middle Cerebral Artery Infarction : Persistent Hyperintensity on Diffusion-Weighted MRI Over 8 Months.

A lesion that is hyperintense on diffusion-weighted imaging (DWI) and hypointense on the apparent diffusion coefficient (ADC) map is a characteristic magnetic resonance imaging (MRI) finding in acute ischemic infarction. In some cases, however, these findings can persist for a few months after infarct onset. It is thought that these finding reflect the different evolution speeds of the infarcted tissue. We report a patient with a right middle cerebral artery territory infarction with persistent hyperintensity on DWI and hypointensity on the ADC map for over 8 months. To our knowledge, this is the most persistent case of hyperintensity lesion on DWI and the serial MRI images of this patient provide important information on the evolution of infarcted tissue.
