background and importance: disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. even after the introduction of high-resolution magnetic resonance imaging (mri), it is still frequently misinterpreted as neoplastic masses. unfortunate...

BACKGROUND AND PURPOSE The multisociety task force descriptively defined abnormal lumbar disk morphology. We aimed to use their definitions to provide a higher level of evidence for the validation of MR imaging in the evaluation of this pathology in patients who have undergone diskectomy by retrospectively classifying their preoperative MRI. MATERIALS AND METHODS This retrospective, instituti...

Disk fragment relocation is commonly limited to the anterior epidural space, although posterior epidural movement of a sequestrated disk piece to the posterior epidural space is infrequent. We present an uncommon case of dorsal extradural sequestration of lumbar disk herniation. A 77-year-old man presented with severe leg pain, low back pain, and urinary incontinence. Deep tendon reflexes were ...

Bronchopulmonary sequestration is a rare congenital lung malformation characterized by an abnormal segment of bronchopulmonary tissue supplied by an anomalous systemic artery. The diagnosis may be easily missed in adults, as many of the symptoms overlap with other pulmonary processes. Surgical resection provides definitive management and is usually reserved for patients with symptoms. This arti...

Pulmonary sequestration has attracted considerable attention in recent years. Many papers reporting typical cases have appeared in the literature. Repetition of material already extensively reported will not be attempted (Bariety and Coury, 1947; Pryce, Sellors and Blair, 1947; Bruwer, Clagett and McDonald, 1950,1954; Kergin, 1952; Santy, Berard, Gaby and Huu (1952); Boyd, 1953; Hertzog, Toty, ...
