Primary intracranial malignant melanoma is a very rare and highly aggressive tumor with poor prognosis. A 66-year-old female patient presented a headache that had been slowly progressing for several months. A large benign pigmented skin lesion was found on her back. A brain MRI showed multiple linear signal changes with branching pattern and strong enhancement in the temporal lobe. The cytological and immunohiostochemical cerebrospinal fluid examination confirmed malignant melanoma. A biopsy confirmed that the pigmented skin lesion on the back and the conjunctiva were benign nevi. We report a case of primary intracranial malignant melanoma and review relevant literatures.

Intracranial arachnoid cyst is presumed to be a developmental anomaly and its natural history is not well defined. Often it is detected incidentally in a asymptomatic patient and hemorrhagic events of arachnoid cyst following head injury are rarely reported. We report hemorrhagic complications including two intracystic hemorrhages, two subdural hematomas, and an epidural hematoma in 5 patients with intracranial arachnoid cyst after minor head injury and review pertinent literatures.

Spontaneous intraspinal and intracranial subdural hematomas (SDHs) are rare, potentially life-threatening complications. We present the case of a 38-yearold highly active antiretroviral therapy-naïve human immunodeficiency virus (HIV)-positive patient who developed simultaneous intraspinal and intracranial SDHs without hemostatic abnormalities. The patient presented with acute lower limb weakness and back pain, and later developed neurological symptoms, including diplopia and incontinence. This case highlights the importance of considering SDHs in HIV-positive patients presenting with neurological symptoms, and underscores the need for prompt diagnosis and multidisciplinary management.

뇌정맥발달기형은 일반적으로 증상을 유발하지 않는 흔한 두개 내 혈관 기형이다. 뇌정맥발달기형과 관련된 출혈은 동반된 해면상 기형이 원인인 경우가 대부분인 것으로 알려져 있으며, 뇌정맥발달기형 내 혈전증이 뇌출혈을 일으킨 경우는 극히 드물게 보고되어 있다. 저자들은 혈전증을 유발할 수 있을 것으로 보이는 특이한 구조의 뇌정맥발달기형을 가진 환자에서 혈전증과 큰 뇌출혈이 생긴 1예를 경험하였기에 컴퓨터단층촬영 소견과 자기공명영상 소견을 보고하고자 한다.

Nontraumatic intracranial subarachnoid hemorrhage (SAH) attributable to the thoracolumbar dural arteriovenous fistulas (DAVFs) has been extremely rare. A 41-year-old male patient was admitted with severe acute headache, neck stiffness, and pronounced low-back pain radiating to both legs. The T2-weighted MR imaging showed irregular signal void and enlarged, varix like pouch formation with spinal cord compression at the T11-12 level. The angiogram revealed a DAVF. We report a DAVF case with SAH that revealed an extensive infarction from C5 to the conus medullaris after undergoing operative treatment.

Periodic lateralized epileptiform discharges(PLEDs) are usually seen in acute and subacute cerebral lesions. Occasionally PLEDs could be observed in persistent structural lesions. We observed PLEDs-plus in a patient with right basal ganglionic hemorrhage, at 10 months and 13 months after the stroke. The patients suffered two seizures 3 months and 5 days before recording of EEG. PLEDs-plus may persist as an interictal abnormal finding and the rhythmic discharge of that may be increased by a seizure.

Traumatic intracranial aneurysms (TICAs) are rare and are associated with high rates of morbidity and mortality. TICAs usually result from head injuries caused by traffic accidents, industrial accidents, or gunshots. We report a traumatic aneurysm of the callosomarginal artery-cortical artery junction arising from a penetrating injury by scissors. A 51-year-old woman was admitted to our hospital after suffering a penetrating injury caused by scissors. Computed tomography (CT) and CT-angiography demonstrated a right orbital roof fracture, subarachnoid hemorrhage, frontal lobe hemorrhage, intraventricular hemorrhage, and a traumatic aneurysm of the right callosomarginal artery-cortical artery junction. We trapped the traumatic aneurysm and repositioned a galeal flap. Postoperative CT showed a small infarction in the left frontal lobe. Follow-up angiography two months later showed no residual aneurysm. We suggest that an aggressive surgical intervention be performed whenever TICA is diagnosed.

Post-hemorrhagic hydrocephalus (PHH) in preterm infant is common, life-threatening and the main cause of bad developmental outcomes. Ventriculoperitoneal (VP) shunt is used as the ultimate treatment for PHH. Low birth weight and low gestational age are the combination of worse prognostic factors while the single most important prognostic factor of VP shunting is age. Aggressive and early intervention have better effect in intraventricular hemorrhage and intracranial pressures control. It reduces infection rate and brain damage resulted in delayed shunt insertion. It is extremely important to let PHH infants get older and gain weight to have internal organs to be matured before undergoing VP shunt. As premature infants undergo shunt after further growth, shunt-related complications would be reduced. So temporary surgical intervention is critical for PHH infants to have them enough time until permanently shunted.

Temple trauma that appears initially localized to the skin might possess intracranial complications. Early diagnosis and management of such complications are important, to avoid neurologic sequelae. Non-penetrating head injuries with intracranial hemorrhage caused by a driven bone fragment are extremely rare. A 53-year-old male was referred to our hospital because of intracerebral hemorrhage. He was a mechanic and one day before admission to a local clinic, tip of metallic rod hit his right temple while cutting the rod. Initial brain computed tomography (CT) and magnetic resonance imaging demonstrated scanty subdural hematoma at right temporal lobe and left falx and intracerebral hematoma at both frontal lobes. Facial CT with 3-D reconstruction images showed a small bony defect at the right sphenoid bone's greater wing and a small bone fragment at the left frontal lobe, crossing the falx. We present the unusual case of a temple trauma patient in whom a sphenoid bone fragment migrated from its origin upward, to the contralateral frontal lobe, producing hematoma along its trajectory.

Dural arteriovenous fistula (AVF) is very rare, acquired lesion that may present with intracranial hemorrhage or neurological deficits. The etiology is not completely understood but dural AVF often has been associated with thrombosis of the involved dural sinuses. To our knowledge, this is the first well documented intracranial hemorrhage case caused by dural AVF following microvascular decompression for hemifacial spasm. A 49-year-old male patient had left microvascular decompression of anterior inferior cerebellar artery via retrosigmoid suboccipital craniotomy. The patient was in good condition without any residual spasm or surgery-related complications. However, after 10 months, he suffered sudden onset of amnesia and dysarthria. Computed tomography and magnetic resonance imaging revealed the presence of dural AVF around the left transverse-sigmoid sinus. The dural AVF was treated with Onyx$^{(R)}$ (ev3) embolization. At the one-year follow up visit, there were no evidence of recurrence and morbidity related to dural AVF and its treatment. This case confirms that the acquired etiology of dural AVF may be associated with retrosigmoid suboccipital craniotomy for hemifacial spasm, even though it is an extremely consequence of this procedure.
