Intercostal lung hernia

Dec 3, 2024 | radiopaedia.org | Yuranga Weerakkody |Craig Hacking

An intercostal lung hernia is a form of lung herniation and is defined as a protrusion of pulmonary tissue and pleural membranes beyond the confines of the thoracic cavity through an intercostal defect/opening in the chest wall. Intercostal lung herniations are considered the commonest form of lung herniation. Patients can be asymptomatic or present with localized chest pain (latter especially in patients with prior thoracotomy or chest tube placements). They may be congenital or acquired.

Wernicke's area (Brodmann area 22) is an area of the posterior temporal lobe in the dominant hemisphere concerned with the receptive components of speech. Gross anatomyWernicke's area is located in the superior temporal gyrus, posterior to the posterior commissure line. RelationsIt is bounded superiorly by the angular gyrus. Blood supplyArterial supply is via the inferior terminal branch of the middle cerebral artery. Related pathologyWernicke aphasiastrokebrain tumors
Right pulmonary artery

Nov 22, 2024 | radiopaedia.org | Craig Hacking |Joachim Feger

The right pulmonary artery (RPA) is one of the branches of the pulmonary trunk, branching at the level of the transthoracic plane of Ludwig. It is longer than the left pulmonary artery and courses perpendicularly away from the pulmonary trunk and left pulmonary artery, between the superior vena cava and the right main bronchus.

The cochlear duct (also known as the scala media) is an endolymph-filled cavity located between the scala vestibuli (upper) and the scala tympani (lower) in the cochlea which is part of the inner ear along with the vestibular apparatus 1,4. The cochlea is located in the bony labyrinth, itself found in the temporal bone 2. The cochlear duct is a cavity filled with endolymph and is a component of the membranous labyrinth of the ear 4. It is held in position by the lamina of the modiolus 1.
Utricle (ear) | Radiology Reference Article | Radiopaedia.org

Jul 29, 2024 | radiopaedia.org | Craig Hacking

The utricle is a small membranous sac (part of the membranous labyrinth) and paired with the saccule lies within the vestibule of the inner ear. It has an important role in orientation and static balance, particularly in horizontal tilt. The vestibule is located within the bony labyrinth (temporal bone) of the inner ear 2 (inferior to the semicircular canals 1). The utricle and the saccule are co-located within the vestibule 3.

The inner ear refers to the bony labyrinth, the membranous labyrinth and their contents. It may also be referred to as the vestibulocochlear organ, supplied by the vestibulocochlear nerve (CN VIII).
Cochlea | Radiology Reference Article | Radiopaedia.org

The cochlea (plural: cochleae) is part of the inner ear osseous labyrinth found in the petrous temporal bone. It contains the cochlear duct, part of the membranous labyrinth which senses hearing. Gross anatomyThe cochlea is a shell-shaped spiral that turns between two-and-a-half and two-and-three-quarters times around the modiolus (a central column of porous bone).
Semicircular duct

Jul 29, 2024 | radiopaedia.org | Craig Hacking

The semicircular ducts are the part of the membranous labyrinth that are contained in the semicircular canals of the osseous labyrinth, concerned with rotational equilibrium. Like the other parts of the membranous labyrinth, the ducts contain endolymph and are surrounded by perilymph. The crura membranacea (membranous crura) is the name given to the two ends of each semicircular duct as they pass into the utricle.
