- Preferential Location for Arterial Dissection Presenting as Golf-Related Stroke
Seven patients with golf-related strokes were imaged and the literature was reviewed for similar cases, which generated a total 14 such occurrences. The most common time of symptom onset occurred during the golf swing and over one-half of patients damaged an extracranial vertebral artery with most dissections involving the right side. Of a total of 14 dissections, 7 patients had complete symptom resolution and returned to normal.
- Subcortical Cystic Lesions within the Anterior Superior Temporal Gyrus: A Newly Recognized Characteristic Location for Dilated Perivascular Spaces
Fifteen patients with unusual dilated perivascular spaces in the subcortical white matter of the anterior superior temporal gyrus were presented. In one, pathology showed gliosis and innumerable perivascular spaces. Findings that suggest cysts in this location were perivascular spaces include: lack of symptoms, proximity to the subarachnoid space, adjacent blood vessels, and stability over time.
- MRI Findings in Autoimmune Voltage-Gated Potassium Channel Complex Encephalitis with Seizures: One Potential Etiology for Mesial Temporal Sclerosis
Voltage-gated potassium channel complex encephalitis is a common form of autoimmune encephalitis presenting with intractable seizures that may respond to immunotherapy. These authors reviewed the imaging findings in 42 such patients and the most common abnormalities noted were enlargement, T2 hyperintensity, contrast enhancement, and restricted diffusion in the mesial temporal lobes with subsequent development of hippocampal atrophy. Because the disease can be confirmed easily by the presence of voltage-gated potassium channel complex antibodies, these imaging findings should prompt serologic testing.
