Position-dependent right-to-left shunt causing a brain abscess.
A 50-year-old man suffering from generalized convulsions and right quadrantic hemianopia was admitted to the hospital. Contrast-enhanced magnetic resonance imaging showed an enhanced ring in the left parieto-occipital lobe, suggesting a brain abscess (Figure 1). The patient underwent an immediate craniotomy and drainage. Culture of pus yielded -hemolytic streptococci. Brain abscesses are often ...
متن کاملThe prevalence of right to left shunt in chronic obstructive pulmonary disease patients with increased pulmonary hypertension
Background: One of the important etiologies for cryptogenic stroke is paradoxical embolization secondary to Patent Foramen Ovale (PFO). Foramen ovale can secondarily reopen due to Pulmonary Arterial Hypertension (PAH) which is common among the older age. PAH is known as a frequent and life threatening complication of COPD. The aim of this study was to determine the prevalence of PFO between COP...
متن کاملHereditary hemorrhagic telangiectasia patient presenting with brain abscess due to silent pulmonary arteriovenous malformation
Hereditary hemorrhagic telangiectasia is a rare autosomal dominant inherited disease that is usually complicated by visceral vascular malformations. Patients harboring such malformations are at increased risk of brain abscess formation, which despite advances in diagnostic and surgical methods remains a life threatening medical emergency with high mortality and morbidity rates. In the present r...
متن کاملRight-to-left shunt with hypoxemia in pulmonary hypertension
BACKGROUND Hypoxemia is common in pulmonary hypertension (PH) and may be partly related to ventilation/perfusion mismatch, low diffusion capacity, low cardiac output, and/or right-to-left (RL) shunting. METHODS To determine whether true RL shunting causing hypoxemia is caused by intracardiac shunting, as classically considered, a retrospective single center study was conducted in consecutive ...
متن کاملSuperior Vena Cava Syndrome Associated with Right-to-Left Shunt through Systemic-to-Pulmonary Venous Collaterals
Superior vena cava (SVC) obstruction is associated with the gradual development of venous collaterals. We present a rare form of systemic-to-pulmonary subpleural collateral pathway that developed in the bridging subpleural pulmonary veins in a 54-year-old woman with complete SVC obstruction. This uncommon collateral pathway represents a rare form of acquired right-to-left shunt due to previous ...
