Enlarged perivascular space mimicking mesencephalothalamic cystic tumor

Perivascular spaces (PVSs) of the brain, also known as Virchow-Robin spaces are pial-lined interstitial fluidfilled structures that surround the small vessels as they extend into the brain parenchyma. PVSs, which are smaller than 2 mm can be seen in all age groups.1,2 Occasionally, PVSs may become large, cause mass effect and be misdiagnosed as a cystic neoplasm. These giant spaces are most com...

Enlarged Parent Artery Lumen at Aneurysmal-Neck Segment in Wide-Necked Distal Internal Carotid Artery Aneurysms

PURPOSE Hypothesizing that the parent artery (PA) diameter of the aneurysm-neck segment is larger than those of normal segments, especially in wide-necked aneurysm cases, we conducted 3D angiographic analyses in wide-necked aneurysm cases focusing on the luminal morphologic change of the PA. MATERIALS AND METHODS Under the approval of local IRB, we enrolled 26 patients with distal internal ca...

Artery to Cystic Duct: A Consistent Branch of Cystic Artery Seen in Laparoscopic Cholecystectomy

Uncontrolled arterial bleeding during laparoscopic cholecystectomy is a serious problem and may increase the risk of bile duct damage. Therefore, accurate identification of the anatomy of the cystic artery is very important. Cystic artery is notoriously known to have a highly variable branching pattern. We reviewed the anatomy of the cystic artery and its branch to cystic duct as seen through t...
