Giant Leaking Colloid Cyst Presenting With Aseptic Meningitis Review of the Literature and Report of a Case.
Colloid cysts are benign third ventricle lesions that need to be diagnosed correctly because of their association with sudden death. Chemical or aseptic meningitis is a rare presentation of a colloid cyst. ⋯ Chemical or aseptic meningitis is an unusual clinical manifestation of a colloid cyst, complicating the differential diagnosis, especially in the elderly.

Aortic root dimension (ARD), an echocardiographic marker of aortopathy, has recently been associated with intracranial aneurysm eccentricity, suggesting a common underlying pathophysiology between intracranial aneurysm and aortopathy. ⋯ Fusiform aneurysms are correlated with larger ARD than saccular aneurysms, suggesting a shared pathophysiologic mechanism with aortopathy.

We sought to describe complications after resection for meningioma with the use of longitudinal administrative data, which our group has shown recently to be superior to nonlongitudinal administrative data. ⋯ In this study, we report complication rates in patients undergoing resection for meningioma. Because of the longitudinal nature of the MarketScan database, we were able to capture a wide array of specific postoperative complications associated with meningioma resection procedures. Care should be taken in the selection of candidates for meningioma resection.

Julius Caesar's epilepsy: Was it caused by a brain arteriovenous malformation?
Julius Caesar (100-44 BC) was one of the most charismatic political figures in history. Best remembered for his military achievements, he was also a writer, historian, and statesman. ⋯ In this essay, we highlight the life of Julius Caesar, with emphasis on the potential origin of his sickness. Although a definitive diagnosis obviously cannot be made, as new published studies showed a possible cerebrovascular etiology, a new hypothetical diagnosis is presented.

Comparative Study
G protein-coupled estrogen receptor levels after peripheral nerve injury in an experimental rat model.
To assess whether G protein-coupled estrogen receptor (GPER) levels were altered during crush-induced peripheral nerve injury in an experimental rat model. ⋯ Our results demonstrate that a basal level of GPER expression occurs in peripheral nerve tissue. The lowest level was detected 1 hour after crush injury, and the highest levels of GPER were detected 12 hours and 24 hours after trauma. Further trials on larger series are required to elucidate the role of GPER in terms of protection and treatment after nerve injury.
