The aim of study was to review our patient population to determine whether there is a critical aneurysm size at which the incidence of rupture increases and whether there is a correlation between aneurysm size and location. ⋯ Ruptured aneurysms in the ACA were smaller than those in the MCA. The most prevalent aneurysm size was 3-6 mm in the MCA (55.73%), 3-6 mm in the ACoA (57.57%) and 4-6 mm in the PCoA (42.30%). The more prevalent size of the aneurysm to treat may differ in accordance with the location of the aneurysm.

Radiographic parameters of segmental instability in lumbar spine using kinetic MRI.
To investigate the effectiveness of radiographic parameters on segmental instability in the lumbar spine using Kinetic magnetic resonance imaging (MRI). ⋯ This study showed that the presences of either Grade IV DD or grade 3 FJO with LFH at L4-L5 were good indicators for segmental instability. Therefore, using these parameters simultaneously in patients with segmental instability would be useful for determining candidacy for surgical treatment.

Repeated intracerebral hemorrhage from developmental venous anomaly alone.
Developmental venous anomalies (DVAs) are hemodynamically low flow, low resistance vascular malformations without clinical significance. Although most DVAs are asymptomatic and are found incidentally, sometimes they can be symptomatic with intracerebral hemorrhage, many of which are usually caused by associated cavernous malformations (CMs) rather than the DVAs themselves. Only a few cases have been reported in the literature where an intracerebral hemorrhage has been caused by a DVA alone. This report describes a case of an intracerebral hemorrhage due to DVA alone with review of the literature.
