Neurenteric cyst of the area postrema.

Neurenteric cysts are CNS lesions most frequently occurring in the spinal cord. Intracranial neurenteric cysts are rarer, typically presenting with headache, mass effect, or location-specific symptoms. The area postrema is known as the emetic center of the brain; lesions can cause nausea and vomiting.

Dramatic intracerebral hemorrhagic presentations of reversible cerebral vasoconstriction syndrome: three cases and a literature review.

Reversible cerebral vasoconstriction syndrome (RCVS) refers to a number of disorders characterized by severe and sudden-onset ("thunderclap") headaches and angiographic features of reversible, segmental, multifocal vasoconstriction of cerebral arteries. Although RCVS generally resolves without significant sequelae, a rare and possibly underrecognized hemorrhagic presentation has a worse potential course. We report three cases of hemorrhagic RCVS and review the literature.

Anti-yo associated paraneoplastic cerebellar degeneration in a man with large cell cancer of the lung.

Purkinje cell cytoplasmic antibody type 1 (PCA-1), or anti-Yo, is the most frequently detected autoantibody in paraneoplastic cerebellar degeneration (PCD). The vast majority of cases of anti-Yo PCD, however, occur in females over 60 years old and are associated with gynecologic tumors. Only 10 cases have been reported in males, and only 2 were associated with cancer of the lung.

Isolated unilateral temporalis muscle hypertrophy.

Isolated unilateral temporalis muscle hypertrophy is an extremely rare cause of swelling in the temple region, with only 7 cases reported in the literature. The authors report the eighth case of this unique occurrence in a 17-year-old boy and review the current literature.

Omega-3 fatty acids as a putative treatment for traumatic brain injury.

Traumatic brain injury (TBI) is a global public health epidemic. In the US alone, more than 3 million people sustain a TBI annually. It is one of the most disabling injuries as it may cause motor and sensory deficits and lead to severe cognitive, emotional, and psychosocial impairment, crippling vital areas of higher functioning.

A tale of Wünderlich syndrome.

Wunderlich syndrome is a rare entity characterized by acute onset of spontaneous, non-traumatic renal hemorrhage into the subcapsular and perirenal spaces. It can be fatal if not promptly recognized clinically and treated aggressively. We report a case of a 63-year-old Caucasian female who was presented to the emergency department with acute onset of sharp abdominal and right flank pain, and hypotension.
