What are hypodense lesions in the spleen?

What are hypodense lesions in the spleen?

Hamartomas of the spleen, also referred to as splenomas, are benign and typically asymptomatic lesions which are often discovered incidentally on imaging. They can be associated with tuberous sclerosis and Wiskott-Aldrich like syndrome. Hamartomas do not possess a capsule.

What does hypodense lesion mean?

Hypodense (less dense): If an abnormality is less dense than the reference structure, we would describe it as hypodense. In the image to the right the solid arrow points to an area that is hypodense relative to the adjacent gray and white matter.

What would cause a lesion 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.

What are splenic lesions?

Splenic lesions are commonly encountered and are often incidental in nature. Benign splenic vascular neoplasms include hemangioma, hamartoma, lymphangioma, extra-medullary hematopoiesis (EMH), and sclerosing angiomatoid nodular transformation (SANT).

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.

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).

Can spleen lesions cause pain?

Hamartomas are benign splenic neoplasms asymptomatic in most of the cases. Symptoms, when present, may either be related to the growth of the mass with abdominal discomfort and pain or be related to a hypersplenism syndrome.

Are malignant liver lesions Hypodense?

Most liver metastases are hypovascular and as a result are hypodense on CT in comparison with normal liver parenchyma during the portal venous phase (PVP). Colon, lung, breast, and gastric cancers are the most common causes of hypovascular liver metastases.

Should pancreatic cysts be biopsied?

Biopsy. In addition to blood tests and imaging tests, we may recommend you have a biopsy. This test involves our pathologists taking a sample of the pancreatic cyst tissue to examine carefully.

How do you treat a lesion on the spleen?

What are the treatment options?

1. surgery called splenectomy that removes part of or the entire spleen.
2. radiation therapy.
3. chemotherapy.

How common are splenic lesions?

Splenic hemangioma is congenital and is the most common benign lesion of the spleen. It is typically an incidental finding, most often occurring in adults between 30 and 50 years of age (16). The prevalence of splenic hemangioma at autopsy ranges from 0.3% to 14%.
