Pencils are common instruments for children to use and play with. This report describes an unusual penetrating orbitocranial injury in a 5-year-old girl who was struck in her facewith a pencil. She was holding it at a desk, and her friend pushed her back. The pencil penetrated the left lower eyelid and went deep into the right frontal lobe through the base of the skull. It was removed at the emergency room, after which brain CT was performed to detect the development of an intracranial hematoma. No complications occurred after conservative management with antibiotics and an antiepileptic drug. Pencils can be hazardous to children, and a penetrating head injury with a pencil may be managed without cranial surgery.

Object : We intended to investigate the relationship between the degree of injury on MRI and the outcome of the patients with diffuse axonal inury. Method : From january, 1995 to march, 1999, 22 patients were supposed to have diffuse axonal injuries by means of their neurologic signs and MRI. We investigated their prognosis according to CT, MRI and initial neurologic findings. Result : 1) The lesions were mainly located at white matter of cerebrum, corpus callosum, brainstem, and basal ganglia. 2) The lesions of white matter were most commonly in the frontal lobe and temporal lobe. 3) The majority of corpus callosal lesions were located in the posterior body and splenium, but anterior corpus callosal lesions combined with posterior lesions were not found. 4) Brainstem lesions, all non-hemorrhagic, were mostly located in the dorsolateral aspect, not be found on CT. 5) The brainstem lesions were found in 10 cases among total 22 cases, and corpus callosal lesions were accompanied with 8 cases of brainstem lesions. 6) The patients with brainstem lesions had worse prognosis. Conclusion : It is important and reasonable to take brain MRI to identify the brainstem lesions in any cases of suspicious diffuse axonal injury, and we should remind that the diffuse axonal injury with stem lesion has worse prognosis.

Objective : Streptococcus pyogenes is a beta-hemolytic bacterium that belongs to Lancefield serogroup A, also known as group A streptococci (GAS). There have been five reported case in terms of PubMed-based search but no reported case of brain abscess caused by Streptococcus pyogenes as a result of penetrating skull injury. We present a patient who suffered from penetrating skull injury that resulted in a brain abscess caused by Streptococcus pyogenes. Methods : The patient was a 12-year-old boy who fell down from his bicycle while cycling and ran into a tree. A wooden stick penetrated his skin below the right lower eyelid and advanced to the cranium. He lost consciousness on the fifth day of the incident and his body temperature was measured as $40^{\circ}C$. While being admitted to our hospital, a cranial computed tomography revealed a frontal cystic mass with a perilesional hypodense zone of edema. There was no capsule formation around the lesion after intravenous contrast injection. Paranasal CT showed a bone defect located between the ethmoidal sinus and lamina cribrosa. Results : Bifrontal craniotomy was performed. The abscess located at the left frontal lobe was drained and the bone defect was repaired. Conclusion : Any penetrating lesion showing a connection between the lamina cribrosa and ethmoidal sinus may result in brain abscess caused by Streptococcus pyogenes. These patients should be treated urgently to repair the defect and drain the abscess with appropriate antibiotic therapy started due to the fulminant course of the brain abscess caused by this microorganism.

We presented with a patient who showed injury of the cingulum and fornix by penetration of a foreign body into the brain on diffusion tensor tractography (DTT). A 63-year-old man suffered a brain injury by a part of a power saw blade that was suddenly detached from a power saw during work. A part of the power saw blade penetrated his right frontal skull and advanced to the right posterior horn of the lateral ventricle. This penetration caused traumatic intracerebral hemorrhage in the right frontal lobe and intraventricular hemorrhage in the lateral ventricle. He underwent craniotomy and removal of intracranial foreign bodies (bony pieces and saw blade). The patient's Memory Assessment Scale scores were 74 (4%ile) for global memory, 78 (7%ile) for verbal memory, and 80 (9%ile) for visual memory. DTTs showed disruptions in the anterior portion of the fornical body, right fornical crus, the anterior portion of the right cingulum, and the middle portion of the left cingulum, compared to the control. It seems that the sustained memory impairment of this patient might be related to injury of the cingulum and fornix.

Composite skull defects in patients with severe head injuries are very challenging to manage. The dilemma when deciding whether to perform a definitive reconstruction is how long to wait for physiological recovery before an intervention complicates the situation. The inability of such patients to tolerate prolonged anesthetic exposure is a driving factor for performing the minimal intervention necessary to facilitate recovery. Herein, we present a case involving the successful immediate reconstructive treatment of a severely head-injured adolescent with a composite scalp defect secondary to trauma. A 14-year-old boy sustained a severe head injury from a motor vehicle accident with a composite scalp defect in the right fronto-parietal region. The frontal lobe was exposed, and the right eye was crushed and devitalized. The patient was deeply unconscious for 3 days, without any significant improvements before reconstructive surgery was proposed due to fear of possible meningitis resulting from the exposure of brain structures. We successfully managed the patient with a fronto-parieto-occipital flap, after which the patient promptly recovered consciousness.

목적: TBI 환자의 SPECT상 혈류장애를 보이는 부위의 분포를 조사하였으며 대뇌피질과 동반된 시상의 혈류변화를 관찰하여 환자의 인지 및 행동 장애 정도를 예측 할 수 있는지 알아보고자 하였다. 대상 및 방법: TBI 후 $0.5{\sim}55$개월까지(평균 10.3개월) 뇌손상 평가를 위해 MRI영상과 Tc-99m ECD SPECT를 시행한 103명의 환자를 대상으로 하였고 남자 81명과 여자 22명이었으며, 평균연령은 $34.7{\pm}15.4$세였다. 대상환자들은 MRI영상에서 정상, 국소손상 또는 미만성 손상여부에 따라 3군으로 나누었다. 신경심리학적 검사는 정신과 의사에 의한 행동 및 성격변화의 관찰과 임상심리사에 의한 인지기능검사에 의해 총 11개의 항목이 평가되었다. SPECT에서 혈류감소를 보이는 대뇌피질의 분포를 비교하였으며 대뇌피질과 시상의 혈류감소를 같이 보인 경우와 시상의 혈류가 정상인 경우로 나누어 인지 및 행동 장애정도와 관계가 있는지 Mann-whitney의 U검정을 이용하여 유의성을 알아보았다 결과: 혈류감소를 보인 병변의 분포는 전두엽(1군 42.3%, 2군 34.5%, 3군 33.3%), 측두엽($24{\sim}26%$), 시상($21{\sim}22.4%$), 두정엽과 후두엽(10%이하)순이었다. 또한 대뇌피질과 시상의 혈류감소가 같이 있었던 경우와 시상이 정상 혈류를 보였던 경우 신경정신과적 증상을 보인 항목 수와 비교한 결과 1군에서는 전자와 후자의 경우 각각 $4.7{\pm}1.5$개와 $3.2{\pm}1.4$개였으며, 2군에서 $5.0{\pm}1.1$개와 $4.8{\pm}1.2$개, 3군에서는 $6.8{\pm}1.8$개와 $6.3{\pm}1.1$개로 MRI에서 손상의 정도가 많을수록 신경정신과적 후유증은 많았으나 SPECT에서 시상의 혈류감소 유무에 따른 증상의 심각성과 관계는 1군에서만 유의하였다(p=0.002). 결론: TBI 후 기질적 정신장애를 갖는 환자의 뇌혈류 SPECT에서 혈류감소를 보이는 병변은 주로 전두엽, 측두엽, 시상순으로 많았고 특히 전두엽은 MRI에서 정상을 보인 군에서 더욱 많은 비율을 차지하였다. MRI에서 정상일 때 SPECT에서 대뇌피질과 시상의 혈류감소가 같이 동반된 경우 시상이 정상혈류를 보인 경우보다 인지 및 행동장애의 심각성과 유의한 관계를 보였다.

The traumatically induced mass lesions of the posterior cranial fossa are unusual. Various types of traumatic posterior fossa hematoma have been described ; the most common forms is epidural hematomas, and frequently traumatic intracerebellar hemorrhage is encountered. A sixty-six-old male patient was initially presented with the occipital skull fracture and contusional hemorrhage on the both frontal lobe, a developed delayed cerebellar hemorrhage. The patient was operated for hematoma removal with good postoperative recovery. We advise a consideration for delayed intracerebellar hematoma in patients with cerebellar contusion following trauma.

Penetrating facial wounds are uncommon and are usually life threatening because of the possibility of brain damage. There are three possible pathways for penetrating the cranium through the orbit: via the orbital roof, via the superior orbital fissure, or between the optic canal and lateral wall of the orbit. Brain injuries resulting from the penetrating wounds show extensive parenchymal damage, hemorrhage, and brain edema. Transorbital penetrating wounds can lead to diverse lesions of the optical apparatus, including the eye globe, the optical nerve, and the chiasm. Moreover, intracerebral structures may be hurt, and bleeding and infection may occur. Early diagnosis and prompt debridement are the fundamental factors affecting the outcome of a penetrating facial wound. An 87-year-old man was admitted to the emergency department with a grinder impacted into the medial aspect of the right eye. On presentation, the man was fully conscious with a Glasgow Coma Scale score of 15 and complained of a visual disturbance of the right eye. Computed tomography demonstrated a right orbital medial and inferior wall fracture, a frontal bone fracture, and a contusional hemorrhage in frontal lobe of the brain. A craniotomy with hematoma removal and repair of the orbital floor was done. He showed no neurological deficits except right visual loss. This appears to be the first report of a man with a penetrating facial wound caused by a grinder, who presented with a potentially disastrous craniocerebral injury that did not lead to any serious neurological seguelae.
