What is a pseudotumor in lungs?

A pulmonary pseudotumor is no more than ‘something’ which mimics a tumor. Most frequently it is caused by a loculated pleural effusion (pleural pseudotumor) trapped in the pleural fissures. Other entities which have been described with the term pseudotumors include: round atelectasis.

What is inflammatory lung lesion?

When an infection or illness inflames lung tissue, a small clump of cells (granuloma) can form. Over time, a granuloma can calcify or harden in the lung, causing a noncancerous lung nodule. A neoplasm is an abnormal growth of cells in the lung. Neurofibromas are a type of noncancerous neoplasm.

What is uremic lung?

Uraemic lung is a severe pulmonary complication observed in patients with uraemia.1 Besides fluid overload, it could be attributed to miscellaneous mechanisms, such as increased lung vascular permeability and inflammation induced by chemokines and leucocytes.1 ,2 It is important to differentiate uraemic lung from other …

What is a pseudotumor mass?

Introduction. First characterized by Brunn in 1939,1 inflammatory pseudotumor (IP) is an exceedingly rare benign condition that often presents as a locally invasive mass. IP is named for its ability to mimic invasive malignancies on clinical presentation, imaging, and histology.

What is the main cause of uremia?

Uremia most often occurs due to chronic kidney disease (CKD) that may lead to end-stage renal (kidney) disease (ESKD), but can also occur quickly leading to acute kidney injury and failure (AKI) that is potentially reversible.

How do you get uremia?

Uremia occurs when your kidneys become damaged. The toxins, or bodily waste, that your kidneys normally send out in your urine end up in your bloodstream instead. These toxins are known as creatinine and urea. Uremia is a serious condition and, if untreated, can be life-threatening.

What causes inflammatory pseudotumor?

The causes of inflammatory pseudotumor are unknown. Some authors believe this tumor is a low-grade fibrosarcoma with inflammatory (lym- phomatous) cells.

How do you treat orbital pseudotumor?

Mild cases may go away without treatment. More severe cases most often respond well to corticosteroid treatment. If the condition is very bad, the swelling may put pressure on the eyeball and damage it. Surgery may be needed to remove part of the bones of the orbit to relieve the pressure.

How common are coin lesions in pulmonary xanthomatous nodules?

Isolated pulmonary xanthomatous nodules which present as coin lesions are uncommon. The gross resemblance of the lesion to a neoplasm and the peculiar microscopic characteristics, especially as seen in frozen sections, may lead to diagnostic errors.

What does it mean when you have nodules in your lungs?

Pulmonary Nodules. There are two types of growths in the lung called pulmonary nodules: benign or malignant. Causes include infections and non-infectious diseases such as sarcoidosis.

How often are pulmonary nodules found on chest xray?

Countless pulmonary nodules are discovered each year during chest X-rays or CT scans. Most nodules are noncancerous (benign). A solitary pulmonary nodule is found on up to 0.2% of all chest X-rays films.

Is a 30mm lung nodule cancerous?

A larger lung nodule, such as one that’s 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule. If your doctor detects a lung nodule on an imaging test, it’s helpful to compare your current imaging scan with a previous one.
