The arcade-like sign refers to the typical features of perilobular fibrosis found in cryptogenic organising pneumonia 1. It is likely the result of perilobular inflammation and shows itself in the form of an arcade or arched appearance of consolidation bands distributed around the structures surrounding the secondary pulmonary lobules 1 arcade-like sign of perilobular fibrosis describes an arch pattern in more than half of the patient with COP 13 ground glass opacity or crazy paving The reverse halo sign (atoll sign) is considered to be highly specific, although only seen in ~20% of patients with COP 5 Arcade of Frohse. Dr Johannes Schmid and Dr Matt A. Morgan et al. The arcade of Frohse (pronounced \ˈfʁoːzə \) is also known as the supinator arch. The arcade is formed by a fibrous band between the two heads of the supinator muscle. The deep branch of the radial nerve passes beneath the arcade accompanied by vessels known as the leash of. The arcade of Struthers is a thin fibrous aponeurotic band extending from medial head of triceps to medial intermuscular septum situated approximately 6-10 cm proximal to medial epicondyle of the humerus. In most cases this structure is due to a thickening of brachial fascia 3 The sign is classically seen in organizing pneumonia (OP), which is most commonly cryptogenic (COP) but can also be secondary to other causes. However, the sign is only seen in about one-fifth of patients with COP 1
A rim sign has been described on FDG-PET of pulmonary infarction, with mild peripheral tracer uptake, and an absence of uptake centrally 10. Treatment and prognosis. Treating the underlying pulmonary embolism by providing cardiopulmonary support is the initial treatment. Anticoagulation is commenced in patients without risk of active bleeding. Several imaging findings of thoracic diseases have been referred—on chest radiographs or CT scans—to signs, symbols, or naturalistic images. Most of these imaging findings include the air bronchogram sign, the air crescent sign, the arcade-like sign, the atoll sign, the cheerios sign, the crazy paving appearance, the comet-tail sign, the darkus bronchus sign, the doughnut sign, the pattern.
Another sign is non-uniform enlargement of the fascicles, which is seen on the sagittal image (arrow). Radial nerve. The radial nerve can be best identified at the level of the radial head, where you can see superficial and deep branches in the radial tunnel (arrows). This is a very consistent place to find the radial nerve. The deep radial branches form the posterior interosseus nerve which. . This vascular plexus facilitates hematogenous spread of the infection in the paradiskal regions. Batson's paravertebral venous plexus in the vertebra is a valve-less system that allows free flow of blood in both directions depending.
Introduction. Vascular structures in the abdomen and pelvis may be compressed by adjacent anatomic structures, or they may cause compression of adjacent hollow viscera. Thus, compression of the proximal celiac artery, transverse duodenum, left common iliac vein (CIV), left renal vein (LRV), ureteropelvic junction (UPJ), and ureter can occur due.

Causes.—Cubital tunnel syndrome is the second most common neuropathy of the upper limb. There is a physiologic change in the volume of the cubital tunnel during elbow flexion, secondary to tightening of.
Radiological Signs of Airspace Disease. One of the principal limitations of imaging studies is that a multitude of pathological processes in the air spaces manifest in only a limited number of ways: thus, for most airspace diseases, a modular pattern, ground-glass opacification and consolidation represent the range of radiological abnormalities It bears an uncinate (unciform) hamulus (hook of hamate) which projects in a volar fashion from the distal part of its palmar surface. It is the most ulnar based bone within the distal carpal row. It has four surfaces: superior surface: apex of the wedge is narrow, convex, and smooth. inferior surface: concave facets separated by a ridge
Introduction. Acute mesenteric ischemia (AMI) is a rare life-threatening condition, accounting for approximately one in 1000 hospital admissions in European countries and in the United States ( 1 ). The mortality rate for AMI is as high as 50%-69% ( 2 - 4 ); this rate has gradually improved but has not changed remarkably during the past.
