In the immunocompromised patient, multiple small splenic lesions usually represent disseminated fungal disease and microabscesses. The spleen is a relatively rare site for metastatic disease; patients with metastatic lesions in the spleen usually have disease in other sites as well.
What is the most severe complication of bronchial artery embolization?
Bronchoscopy as a combined diagnostic and therapeutic tool may be indicated as a first-line therapy for massive hemoptysis, but it is controversial and often unnecessary prior to BAE as a tool to localize the bleeding site if imaging can demonstrate the most likely source.
Should I be worried about spleen lesions?
The presence of lesions in other organs in addition to the spleen should raise suspicion for metastases or metastatic primary splenic angiosarcoma. Rarely, patients with benign neoplasms may present with abnormal laboratory values, such as thrombocytopenia or anemia.
What is the difference between bronchial artery and pulmonary artery?
Introduction. The lungs are supplied by two separate vascular systems consisting of the pulmonary and bronchial arteries. The pulmonary arteries carry deoxygenated blood at low pressure. The bronchial arteries carry oxygenated blood to the lungs at a pressure six times that of the pulmonary arteries.
What is a cystic lesion on the spleen?
Splenic epithelial cysts, also known as splenic epidermoid cysts or primary splenic cysts, are unilocular fluid lesions with thin and smooth walls and no enhancement. They represent ~20% of cysts found in the spleen, and are usually an innocuous incidental imaging finding.
Are spleen lesions serious?
Hypodense splenic lesions are frequently encountered on abdominal CT images. Although most hypodense lesions of the spleen can be considered benign, some findings and clinical conditions warrant closer attention to the lesion.
Is bronchial artery embolization safe?
Bronchial artery embolization (BAE) is a safe and effective nonsurgical treatment for patients with massive hemoptysis.
How long does bronchial artery embolization take?
Often, several blood vessels have to be embolized for the best treatment of your condition. The procedure may take anywhere between 2 and 4 hours to perform.
Where do bronchial arteries come from?
The bronchial arteries usually originate from the proximal descending thoracic aorta (Fig 1a–1c). They are termed orthotopic when they originate between the superior endplate of the T5 vertebral body and the inferior endplate of the T6 vertebral body.
What is bronchial artery?
In human anatomy, the bronchial arteries supply the lungs with nutrition and oxygenated blood. Although there is much variation, there are usually two bronchial arteries that run to the left lung, and one to the right lung and are a vital part of the respiratory system.
How serious is a cyst on your spleen?
Although a significant percentage of splenic cysts are asymptomatic, larger cysts may cause vague upper abdominal pain as a result of capsular distention or pressure on adjacent organs. Major complications like hemorrhage into the cyst or peritonitis secondary to cyst rupture are rare.
Are splenic lesions cancerous?
The majority of such solid splenic nodules and masses are benign, with hemangioma being the most frequent diagnosis (8,9). However, CT imaging characteristics of benign and malignant splenic masses often overlap, making definitive differentiation difficult (8,10).
