Spontaneous coronary artery dissection is a rarely identified entity whose exact incidence, etiology, pathogenesis, medium-term evolution and optimal treatment have not yet been firmly estabilished. The cause of spontaneous disection remains unclear but theories of etiology include a medial eosinophilic angiitis, pregnancy induced degeneration of collagen and rupture of the vasovasoum. Most paients die suddenly, but a clinical spectrum is seen including and unstable angina, myocardial infarction and cardiogenic shock. We experienced 4 cases with spontaneous coronary artery dissection found angiographically which caused myocardial infarction and unstable angina. Our patients were treated medically.

Idiopathic restrictive cardiomyopathy is characterized by clinical and hemodynamic findings of restrictive cardiomyopathy in the absence of morphologic cause. The differential diagnosis between idiopathic restrictive cardiomyopathy and noncalcified constrictive pericarditis is difficult but the distinction is crucial because of the therapeutic implication. The diagnosis of idiopathic restrictive cardiomyopathy is aided by echocardiography and cardiac catheterization, cardiac magnetic resonance imaging. The patients should be approached systemically to differentiate from noncalcified constritive pericarditis.

Secondary intracranial hypertension (IH) is a syndrome with various etiologies, including a brain tumor, head trauma, hypoparathyroidism, hydrocephalus, meningitis, drug use, or venous obstruction. It is reasonably straightforward to diagnose secondary IH induced by these diseases. However, diagnosing secondary IH induced by unpredictable extracranial lesion is difficult, and is based largely on subtle neurological symptoms or signs and usually can be achieved by an extracranial evaluation. Here we describe four cases of secondary IH with unusual causes.

BACKGROUND AND OBJECTIVES: Congenital nystagmus (CN) is an ocular oscillation that usually manifests during early infancy. To report a novel mutation in FERM domain containing 7 (FRMD7) gene in a Korean family with CN. MATERIALS AND METHODS:Genomic DNA was prepared from peripheral blood leukocytes and direct sequencing of the entire coding and adjacent intronic regions was performed to detect sequence variation of FRMD7 gene, where mutations were found recently in patients with familial CN. The family showed an X-linked pattern of inheritance without father-to-son transmission. RESULTS: Three family members with CN exhibited two sequence variations which were a novel mutation (c. 875T>C; Leu292Pro) and a polymorphism (c. 1403G>A; Arg468His, dbSNP rs#6637934). The proband was hemizygous for both variations and his mother and maternal grandmother were heterozygous carriers. CONCLUSION: This study provides an additional evidence for mutations in FRMD7 as a common cause of X-linked CN and expands its mutation spectrum.

A 52-year-old woman presented with atypical chest pain. Coronary angiography demonstrated multiple microfistulae between left coronary artery and left ventricle (LV) cavity, extensive enough to produce an LV angiogram. This LV angiogram revealed apical hypertrophic cardiomyopathy (HCM) which was confirmed by echocardiography. Coronary steal phenomenon by coronary artery microfistulae and HCM might have a role for developing of angina in patient with apical HCM.

We report on three patients with transient focal neurologic deficits that completely resolved. In all cases, initial perfusion-weighted imaging (PWI) performed 1 hour after being free of symptoms showed a defect in the time-to-peak (TTP) map in the area with normal diffusion-weight imaging (DWI) findings. After 24 hours, DWI showed a high signal intensity in exactly the same area as the TTP defect. Therefore, early PWI provides a rapid evaluation of cerebral hemodynamics in transient ischemic attack.

The tumors containing ganglion cells are rare in the pituitary gland. These tumors are divided into two groups. The first group is the cases of mixed gangliocytoma-adenoma that contained both gangliocytoma and pituitary adenoma elements in the same tumor and the second group is those of gangliocytoma that contained only gangliocytoma element. Since the first description by Kiyono in 1926, 45 cases have been reported. The most common presentation of these tumors is acromegaly and the cases of Cushings disease and galactorrhea-amenorrhea also have been reported. In immunohistochemical study, hypothalamic-releasing hormones are stained in gangliocytoma cells and adenohypophyseal hormones are stained in adenoma cells. The releasing hormones stained in gangliocytoma element and the pituitary hormones stained in adenoma elements are usually closely related but unrelated cases also have been reported. We report a case of a 41 year-old lady with acromegaly which was diagnosed as mixed gangliocytoma-adenoma after surgical removal of the pituitary tumor.

We report a case of recurrent Streptococcus Pneumoniae meningoencephalitis with a transethmoidal meningoencephalocele (TEME) but without cerebrospinal fluid (CSF) leakage. A 35-year-old man was admitted with S. pneumoniae meningitis. He had suffered from four episodes of recurrent pneumococcal meningitis during the previous 4 years. A computed tomography scan of the paranasal sinus showed the TEME protruding through a bony defect of the right frontal base. However, the patient did not have symptoms that could be attributable to CSF leakage, and radioisotope cisternography did not identify a leak. Brain magnetic resonance imaging revealed cortical lesions overlying the TEME, and electroencephalography revealed epileptiform discharges in frontal regions. Appropriate antibiotics therapy without steroids was given to improve his condition. The presented case suggests that even in the absence of clinically demonstrable CSF leakage, an occult skullbase defect and its associated meningoencephalocele should be considered in patients with recurrent bacterial meningitis.

ST-elevation myocardial infarction (STEMI) caused by an acute aortic dissection is relatively rare. A diagnosis of dissection can be missed and the situation can become complicated. We report a patient who presented with acute aortic dissection responsible for STEMI related to a dissecting flap into the right coronary artery. This case emphasizes the need for careful assessment of the aorta in cases of atypical coronary occlusion in patients with STEMI without evidence of atherosclerosis in non-culprit coronary segments. The patient was discharged 7 days after primary percutaneous intervention for STEMI. However, she revisited the emergency department for recurrent chest pain and aortic dissection and was diagnosed and managed successfully with surgery.
