What would cause a lesion on your spleen?
Etiologies for multifocal splenic lesions include infectious and inflammatory processes, primary vascular and lymphoid neoplasms, metastatic disease, vascular processes, and systemic diseases. There is often overlap in the imaging appearance alone, so the clinical setting is very helpful in differential diagnosis.
What is Hypodensity in spleen?
Hypodense splenic lesions are frequently encountered on abdominal CT images. Most hypodense lesions of the spleen can be considered benign. Various parameters in CT – cystic/solid, borders of lesion, enhancement pattern, calcification, fat, etc. can be assessed to differentiate hypodense lesions of the spleen.
How common are splenic lesions?
Small studies report the prevalence of incidental splenic lesions on CT scans performed on trauma patients to be less than 1.5% [2]. Metastases and lymphoma are the two most common splenic malignancies, and although both are very rarely seen in the setting of an incidental finding.
What is heterogeneous lesion in liver?
Benign tumors of the liver are a heterogeneous group of lesions whose detection has greatly increased because of the widespread use of imaging techniques. Only a few types, such as cavernous hemangiomas, focal nodular hyperplasia (FNH), hepatic adenoma (HA), and cysts, are frequent enough to be of clinical importance.
Should I worry about a lesion on my spleen?
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.
How are spleen lesions treated?
Common treatments for spleen cancer include: surgery called splenectomy that removes part of or the entire spleen. radiation therapy. chemotherapy.
What is a splenic infarction?
Splenic infarction occurs when blood flow to the spleen is compromised causing tissue ischemia and eventual necrosis. Splenic infarction may be the result of arterial or venous occlusion.
What are nodules on the spleen?
Splenic siderotic nodules, also known as Gamna-Gandy bodies, of the spleen, are most commonly encountered in portal hypertension. The pathophysiological process is the result of microhemorrhage resulting in hemosiderin and calcium deposition followed by fibroblastic reaction.
What is a heterogeneous lesion?
Lesions with areas that appeared to be of low density as determined subjectively by the reviewing physician were labelled as being heterogeneous in appearance.
What does a nodules on the spleen mean?
The nodular pattern of involvement can mimic lymphoma or metastatic disease to the spleen. The presence of larger, confluent lymph nodes suggests the possibility of lymphoma, and the presence of a primary malignancy suggests metastatic disease.
