Clinical and Anatomical Characteristics of Perforator Aneurysms of the Posterior Cerebral Artery: A Single-Center Experience.

Introduction: Posterior cerebral artery (PCA) aneurysms represent up to 1% of all cerebral aneurysms. P1-P2 perforator aneurysms are thought to be even less prevalent and often require complex treatment strategies due to their anatomical and morphological characteristics, with risk of a perforator infarct. We studied the treatment of P1-P2 perforator aneurysms in a single-center cohort from a high-volume tertiary center, reporting clinical and anatomical characteristics, treatment strategies, and outcomes.

Acute right and left heart failure caused by an intrathoracic stomach.

Hiatus hernia (HH) is a frequent condition and is asymptomatic most of the time. Common symptoms can include epigastric pain, postprandial fullness, and nausea. We report a case of postprandial acute right and left heart failure caused by an intrathoracic stomach in a previously asymptomatic woman.

Complete loss of vision caused by a giant mucocele of the frontal sinus.

The authors report the case of a 75-year-old man presenting with an exceptionally large giant posttraumatic mucocele of the frontal sinus years after a gunshot blast to the head. The lesion had grown so extensively that the right eye had shrunk and calcified, resulting in total monocular blindness, a complication that has been reported only once. To the best of our knowledge, it is the first time that a giant mucocele of such a large size is reported.
