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 does a mass on the spleen mean?
Such incidental findings include masses in the spleen, which have been reported as incidental findings in greater than 14% of autopsies (3), and most commonly represent hemangiomas, cysts, hamartomas, lymphangiomas, or granulomas.
How common are splenic lesions?

What causes lesions on the 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.
Are splenic lesions cancerous?
Splenic metastases are seen in only 2–9% of untreated cancer patients and are seen as isolated splenic lesions in 5.2% of patients[28,29]. Tumors that most commonly metastasize to the spleen include melanoma, and tumors of the breast, lung, ovary, colon, stomach and pancreas.
What does a CT scan of the spleen show?
A CT scan remains the most useful preoperative investigation to measure splenic volume; to exclude lymph nodes at the splenic hilum; and to detect accessory spleens, splenic abscesses, and perisplenitis.
What is the most common benign mass of the spleen?
Hemangioma. Hemangioma is the most common benign neoplasm of spleen and most splenic hemangiomas are found incidentally on imaging.
Can a mass in the spleen be benign?
Most common primary tumours of the spleen are benign and originate from the vascular endothelium and include haemangioma, hamartoma, littoral cell angioma, lymphangioma, haemangioendothelioma, haemangiopericytoma. Non-vascular tumours comprise the inflammatory pseudotumour, fibroma and lipoma [1–6].
What is treatment for a lesion on a spleen?

Are splenic tumors always malignant?
In many cases, splenic masses consist of only benign hematomas or fibrous nodules. However, these masses can sometimes be highly malignant forms of cancer, especially vascular cancer known as hemangiosarcoma.
Are lytic lesions on CT scans always cancer?
Lytic lesions — spots where bone tissue has been destroyed — can be seen in other cancers. Liver lesions are abnormal growths that may be noncancerous (benign) or cancerous. Benign lesions occur for a variety of reasons and are typically not cause for concern. Liver cancer is less common but more serious.
Can lesions on spleen be cancer?
