This case report describes a patient who had a foreign body in transverse sinus. A 35-year-old Korean-Chinese man visited the emergency room with lacerated wound in left eyelid and a foreign body which was stumbled upon in the skull. On examination, there was right side hemianopsia in his left eye, He did not complain any headache or show any abnormal neurological signs, but there was a foreign body at left transverse sinus in computed tomography which was taken at another hospital. There was no intracranial abnormality except the foreign body in computed tomography. Because of the financial problem, additional evaluations were not possible. We herein report a strange case in which the pathway of a foreign body to locate in transverse sinus was ambiguous, and suggest that the foreign body located in transverse sinus might have been the penetrated along the anterior fontanelle and passed through the superior sagittal sinus.

We report a rare case of remote cerebellar hemorrhage after intradural disc surgery at the L1-2 level. Two days after the spine surgery, patient complained unexpected headache, dizziness, nausea and vomiting. From the urgently conducted brain CT, it was reported that the patient had cerebellar hemorrhage. Occipital craniotomy and hematoma evacuation was performed, and hemorrhagic lesion on the right cerebellum was effectively removed. After occipital craniotomy, the patient showed signs of improvement on headache, dizziness, nausea and vomiting. He was able to leave the hospital after two weeks of initial operation without any neurological deficit. Remote cerebellar hemorrhage following spinal surgery is extremely rare, but may occur from dural damage of spinal surgery, accompanied with cerebrospinal fluid leakage. Early diagnosis is particularly important for the optimal treatment of remote cerebellar hemorrhage.

The pupillary size and movement are controlled dynamically by the autonomic nervous system; the parasympathetic system constricts the iris, while the sympathetic system dilates the iris. Under normal conditions, these constrictions and dilations occur identically in both eyes. Asymmetry in the pupillomotor neural input or output leads to impaired pupillary movement on one side and an unequal pupil size between both eyes. Anisocoria is one of the most common signs in neuro-ophthalmology, and the neurological disorders that frequently cause anisocoria include serious diseases, such as vascular dissection, fistula, and aneurysm. A careful history and examination can identify and localize pupillary disorders and provide a guide for appropriate evaluations.

Rhabdoid tumor of the kidney (RTK) is a rare malignancy in infancy. Central nervous system involvement in RTK is already known. However, solitary spinal metastasis in RTK has been hardly reported. The authors report a case of metastatic RTK to spine causing paraplegia in an 8-month-old girl. Since the patient was young, the diagnosis of spine metastasis was delayed until paraplegia was seen after radical nephrectomy. Thorough neurological examination should be performed for early diagnosis of spinal metastasis in young patients with RTK. If there are any abnormal signs in neurologic examination, magnetic resonance images of brain and spine are recommended.

Surgical elevation of the depressed bone is known to be the conventional treatment usually recommended for a simple depressed skull fracture in the adult or pediatric age. The authors introduce, however, a case of depressed skull fracture in an infant which was elevated by means of a cup of breast pump and a suction generator without surgical elevation. In our case, without surgery, a 'cup-shaped' depressed skull fracture in an infant was safely elevated with no neurological signs. This method is considered a simple, effective, safe, and alternative procedure in an infant with simple depressed skull fracture.

A two-year-old male peacock (Pavo cristatus) showed acute watery green diarrhea, followed by neurological signs including torticollis and muscular tremor. By the hemagglutination inhibition test for detecting the antibody against the Newcastle disease virus (NDV), the peacock serum inhibited the agglutination of chicken red blood cells. Grossly distinctive hemorrhagic lesions were found in the mucosa of proventiculus and intestine and lung. The spleen revealed multiple variable sized necrotic foci. Histologically, the mucosa of gastrointestinal track had hemorrhagic lesions and some of them underwent ulceration. The spleen exhibited multiple variable sized necrotic foci in which fibrin exudation was marked. Central nervous system had mild non-suppulative menin-goencephalitis consisting of vasculitis, perivascular hemorrhage, gliosis and meningitis. The cells particularly in the cerebellum were degenerative to necrotic. Some of these nerve cells revealed characteristic peripheral chromatolysis. From the present serological and pathological findings, it is suggested that NDV causing death of peacock was velogenic viscerotropic strain. This is the first report of the occurrence of velogenic viscerotropic NDV in an adult peacock in Korea.

Spontaneous cerebrospinal fluid (CSF) leak is a recognized cause of spontaneous intracranial hypotension (SIH). Subdural hematoma (SDH) is a serious but rare complication of SIH. An autologous epidural blood patch at the CSF-leak site can effectively relieve SIH. We report a case of bilateral SDH with SIH caused by a CSF leak originating at the C1-2 level. A 55-year-old male complained of orthostatic headache without neurological signs. His symptoms did not respond to conservative treatments including bed rest, hydration and analgesics. Magnetic resonance imaging showed a subdural hematoma in the bilateral fronto-parietal region, and computed tomography (CT) myelography showed a CSF leak originating at the C1-2 level. The patient underwent successful treatment with a CT-guided epidural blood patch at the CSF-leak site after trephination for bilateral SDH.

During 22-year period ending in June 1988, operation was performed on 22 patients with primary heart tumor at Yonsei University College of Medicine. Mean age was 38.8*3.03[mean \ulcornerEM] ranging from 14 to 63 years old. Twenty cases were myxomas. Others were fibromyxoma and rhabdomyosarcoma. All patients complained of dyspnea on exertion. Nine cases had palpitation. Other constitutional symptoms were weight loss [7 cases], headache [4 cases], generalized edema [3 cases] and cough [3 cases]. Five cases had neurological symptoms and signs preoperatively. Preoperative NYHA Class was poor [Class II; 8 cases, III; 9 cases and IV; 5 cases]. The most common site of tumor origin was fossa ovalis limbus [16 cases; 72.8%]. Because of severe mitral regurgitation and of recurrent myxoma, 2 cases were reoperated for mitral valve replacement. Postoperative complications were postoperative mitral regurgitation [5 cases; 22.8%] and arrhythmia [4 cases; 18.2%], one of which was supra-His bundle block. All patient survived operation. Follow-up of 15 patients [mean 28.95*8.3 months] was good as functional class 1[8 cases] or II [7 cases]. More effective adjuvant therapy will be necessary to improve long-term prognosis for malignant primary heart tumor.

Isolated hypoglossal nerve palsy is a rare clinical condition and it causes deviation of the tongue and dysarthria. A 50-year-old female presented with tongue deviation to the left and mild dysarthria. She had no remarkable past medical history except several recent upper respiratory infections. On examination, the other cranial nerves were intact and she had no focal neurological signs. The findings of MRI and MR angiography were normal. Cerebrospinal fluid analysis revealed only mild elevation of protein. We diagnosed her as suffering with idiopathic isolated hypoglossal nerver palsy and we administered steroid therapy. The dysarthria was improved, but the tongue deviation still remained at 50 days after onset. We report here on a rare case of idiopathic isolated hypoglossal nerve palsy.

Lateral laminectomy was performed far spinal decompression in 7 thoracolumbar disc herniated dogs. These dogs showed upper motor neurologic signs including kyphosisi urinary dysfunction, and paraplegia or paralysis in hindlimbs. The lesions were evaluated with myelographic findings and predominated in $T_{12}-T_{13}, T_{13}-L_{1} and L_{1}-L_{2}$ discs. Five dogs which were operated within 48 hours after the onset of paraplegia were recovered from kyphosis and sustained the normal gait and walkings furthermore normal urination and defecation were presented within 3 days of postoperation. One dog was expired with steroid induced intestinal bleeding. The other dog operated on 96 hours after the onset of paraplegia was not recovered from neurologic deficits. Spinal decompression technique was considered to be useful method fur improving neurological problems resulted firom thoracolumbar disc herniation, if dogs are operated on early stage of the onset of paraplegia.
