The presence of lung nodules on high resolution CT is a keystone in understanding the appropriate differential. Typically, the distribution of nodules is divided into perilymphatic, centrilobular and random categories. Furthermore, nodules can be ill-defined, implying they are in the alveoli, or well defined, suggesting an interstitial position ...
There may also be multiple nodules. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays [3] and around 1% of CT scans. [4] The nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, [4] especially in older adults and ...
Lung hernia (Sibson hernia) is a protrusion of lung outside of thoracic wall. In 20% patients with lung hernia, the incidence is congenital. In 80% of the cases, the hernia is noted after chest trauma, thoracic surgery or certain pulmonary diseases. [1] Congenital hernia occurs because of the weakness of the suprapleural membrane or neck
Modern detail-oriented scans such as high-resolution computed tomography (HRCT) is the gold standard in respiratory medicine and thoracic surgery for investigating disorders of the lung parenchyma . Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses , as well as to assess lymph node status at ...
A Bochdalek hernia is a congenital abnormality in which an opening exists in the infant's diaphragm, allowing normally intra-abdominal organs (particularly the stomach and intestines) to enter into the thoracic cavity. In the majority of people, the affected lung will be deformed, [3] and the resulting lung compression can be life-threatening ...
The mainstay of non-invasive staging is a CT scan of the chest followed by metabolic imaging with a PET scan. The CT scan shows abnormalities such as a lung nodule or enlarged lymph nodes whereas the PET scan reveals increased metabolism such as occurs in structures which contain rapidly growing cancer cells. PET/CT combined the benefits of ...
The first differentiating factor in hernia repair is whether the surgery is done open, or laparoscopically. Open hernia repair is when an incision is made in the skin directly over the hernia. Laparoscopic hernia repair is when minimally invasive cameras and equipment are used and the hernia is repaired with only small incisions adjacent to the ...
Ultrasound Imaging or a CT scan will provide better imaging for the detection of a hernia than an X-ray. [7] The ultrasound probe should move from lateral to medially, a hypoechoic mass should appear anteriorly and medially to the inferior epigastric artery during Valsalva maneuver. [8]
