What is osseous structures in lungs? Introduction: Pulmonary ossification (PO) is a rare pathologic finding, defined as a widespread heterotopic bone formation within the lungs. PO occurs in two forms. The first form is the nodular circumscribed type; the second form is the racemose or branching type. Males are more often affected than females.Definition. The skeletal system provides support and protection for the body's internal organs and gives the muscles a point of attachment. Humans have an endoskeleton, where our bones lie underneath our skin and muscles. In other animals, such as insects, there is an exoskeleton on the outside of the body. Overview.Occult osseous injuries may result from a direct blow to the bone by compressive forces of adjacent bones against one another or by traction forces during an avulsion injury. Lesions in the tibial plateau, hip, ankle, and wrist are often missed . In a tibial plateau fracture, any disruption of the posterior and anterior cortical rims of the ...The thoracic cage, a flexible framework of bones and cartilage, is conical in shape. It is narrower at the top and broadens to fit and protect some critical organs of respiration and circulation—that is, the lungs and heart. The thoracic cage gives your upper torso structure. Women have smaller cages than men; the capacity is less, and the ...The sternum is the bone that lies in the anterior midline of our thorax. It forms part of the rib cage and the anterior-most part of the thorax. Its functions are to protect the thoracic organs from trauma and also form the bony attachment for various muscles. It is also the center around which the superior 10 ribs directly or indirectly ...

Spinal metastasis is common in patients with cancer. The spine is the third most common site for cancer cells to metastasize, following the lung and the liver. This amounts to 70% of all osseous metastases. Approximately 5-30% of patients with systemic cancer will have spinal metastasis; some studies have estimated that 30-70% of patients ...Pulmonary edema. The function of the alveoli also depends on the sacs being inflated the right amount. Some conditions and injuries can cause overdistention or surfactant dysfunction, which cause the alveoli to collapse. This makes it harder for the lungs to work. Overdistention is overstretching of the alveoli.Purpose: Our purpose was to explore the clinical significance of unexpected osseous foci on 18 F-FDG-PET without correlative CT abnormalities (FWCT) in patients referred for oncologic evaluation. The significance of FDG-avid foci without correlative CT abnormalities has been previously explored in tissues such as breast, lung, liver, and prostate; however, osseous foci without correlative CT ...The Lung and Upper Aerodigestive Cancer Research Group conducts and supports research on the prevention and early detection of lung and head and neck cancers, as well as new approa...Figure 1.

The lung is dark because it is mostly air. Darker areas in the lungs may be cysts or areas of air trapping. Hypodense areas in the mediastinum may be masses, lymph nodes, or cysts. Hypodense blood vessels may be occlusions or clots after contrast is given through a vein. Hypodense areas along the chest wall and ribs may be bone lesions.Structural changes in COPD are found in the central airways, peripheral airways, lung parenchyma, and pulmonary vasculature. Broadly there are two different pathways leading to the same physiologic phenotype: one centered on the small airways and involving mucosal inflammation and structural change, and the other centered on the …The sternum is the elongated bony structure that anchors the anterior thoracic cage. It consists of three parts: the manubrium, body, and xiphoid process. The manubrium is the wider, superior portion of the sternum. The top of the manubrium has a shallow, U-shaped border called the jugular (suprasternal) notch. This can be easily felt at the ...Degenerative lung disease includes diffuse hypertrophic emphysema, bullous emphysema, and "vanishing" or "cotton-candy" lung.
