In radiology, the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction.
The tree-in-bud sign indicates the presence of an infection that has spread endobronchially, and is classically associated with tuberculosis and bronchopneumonia. Read more…

Aberrant subclavian artery
Aberrant subclavian artery, or aberrant subclavian artery syndrome refers to a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch.
The aberrant artery usually arises just distal to the left subclavian artery and crosses in the posterior part of the mediastinum usually behind the esophagus on its way to the right upper extremity. Such course of this aberrant vessel may cause a vascular ring around the trachea and esophaugus. Dysphagia due to an aberrant right subclavian artery is termed dysphagia lusoria. Palsy of the recurrent laryngeal nerve is termed Ortner’s syndrome. Read more…

Pericardial effusion
Pericardial effusion (“fluid around the heart”) is an abnormal accumulation of fluid in the pericardial cavity. Because of the limited amount of space in the pericardial cavity, fluid accumulation will lead to an increased intrapericardial pressure and this can negatively affect heart function. When there is a pericardial effusion with enough pressure to adversely affect heart function, this is called cardiac tamponade. Pericardial effusion usually results from a disturbed equilibrium between the production and re-absorption of pericardial fluid, or from a structural abnormality that allows fluid to enter the pericardial cavity.
