INTRODUCTION Brain abscesses arising from right-to-left cardiac shunting are very rare in adults. CASE PRESENTATION We describe the case of a 47-year-old non-hispanic white male with periodontal disease who developed several brain abscesses caused by Streptococcus intermedius. A comprehensive workup revealed a patent foramen ovale with oral flora as the only plausible explanation for the brai...

OBJECTIVES/HYPOTHESIS While there are many benefits to the endoscopic endonasal approach to the infratemporal fossa, involvement of the petrous portion of the internal carotid artery (ICA) poses a unique challenge. The endoscopic endonasal approach requires establishing the relationship of the petrous ICA to anatomical landmarks to guide the surgeon. This study evaluates the relationship of pet...

We observed that the mobilization of the nerves II, III, VI, VIII, and XII were not easy comparing to other cranial nerves. The subfrontal parenchymal tissue should be removed and the olfactory nerve should be dissected for mobilization of the first cranial nerve. The mobilization of the nerves IV, V, VII, IX, and XI were dramatically remarkable after drilling of superior orbital fissure, foram...

Probable right ventricular dysplasia and a patent foramen ovale resulted in cyanotic heart disease in a patient with some characteristics of Noonan syndrome.

A prominent Eustachian valve (EV) is a common finding in patients with a patent foramen ovale (PFO). Its presence might compromise transcatheter closure of the PFO.

The aim of the study was the retrospective morphological analysis of selected structures of the middle cranial fossa, i.e. foramen ovale and superior orbital fissure, in relation to the external head and cranial diameters in adults from the Lublin region (Poland). The study was performed on data collected during computed tomography examinations of 60 individuals (age 20-30 years), without any c...
