Fibrous dysplasia of the bone in adults is a rare anomaly of skeletal development caused by a defect in differentiation of osteoblasts. This condition is associated with bone pain, bone deformity, and an increased incidence of fracture. Involvement of the skull is associated with headache along with dysmorphic features. Until recently, the principal(More)
Glial cysts of the pineal gland can frequently be found in adults and children, but only rarely do they enlarge to become clinically relevant. We report a unique presentation of a pineal cyst in the midbrain tectum of a 16-month-old girl who initially presented with ptosis and strabismus. Preoperative imaging studies and intraoperative findings revealed no(More)
Distal anterior cerebral artery (DACA) aneurysms represent 2–9 % of intracranial aneurysms. They are often more amenable to surgical rather than endovascular treatment due to the size of parent vessels. We illustrate surgical approaches for DACA aneurysms arising from different segments of the anterior cerebral artery. Cases range from simple unruptured(More)
oyamoya disease (MMD) is characterized by progressive occlusion of the internal carotid arteries or terminal M branches, accompanied by formation of extensive collateral vessels that ordinarily supply the optic nerves, pituitary gland, anterior perforated substance, dura, and other skull base structures. The appearance of these abnormal vessels resembles a(More)
BACKGROUND Patients with moyamoya disease and progressive neurological deterioration despite previous revascularization pose a major treatment challenge. Many have exhausted typical sources for bypass or have ischemia in areas that are difficult to reach with an indirect pedicled flap. Omental-cranial transposition has been an effective, but sparingly used(More)
