2025年1月15日 · There are a number of splenic lesions and anomalies: These usually manifest as splenomegaly. Some can present as distinct lesions (e.g. granulomas).

Tumors of the spleen are rare compared to the incidence of such tumors in other parenchymatous organs. Their classification has varied with both time and author. They can be divided into two main categories: nonlymphoid and lymphoid. The most common ...

Primary malignant neoplasms involving the spleen are lymphoma and angiosarcoma. Primary benign neoplasms involving the spleen include hemangioma, lymphangioma, littoral cell angioma and splenic cyst and solid lesions such as hamartoma and inflammatory pseudotumor. Keywords: Spleen, neoplasms, CT, MRI, FDG-PET.

2021年1月16日 · Most splenic cancers do not start in the spleen, and those that do are almost always lymphomas. Lymphoma is a type of blood cancer that develops in the lymphatic system. It is more common for a lymphoma to start in another part of the lymphatic system and invade the spleen than it is for lymphoma to start in the spleen itself.

Splenic lymphomas and primary splenic angiosarcoma (PSA) are the 2 most common histological types of splenic cancers. This population-based study aimed to investigate the clinical characteristics and survival outcomes of patients with splenic lymphomas or PSA.

2021年3月4日 · There is a wide spectrum of benign and malignant neoplasms of the spleen. Lymphomas and vascular tumors comprise the most common splenic neoplasms. Splenic hemangiomas and angiosarcomas are the most common mesenchymal tumors. Select splenic neoplasms show characteristic distribution and imaging findings to permit precise diagnosis.

Splenic cysts are far more common than solid lesions; true cysts must be differentiated from pseudocysts of the pancreas and from cystic degeneration following splenic contusion or infarction. Cysts may be congenital (epidermoid cysts), infectious (abscess or hydatid cyst), or neoplastic (lymphangioma or angioma with tumor necrosis).

Splenic tumors are uncommon lesions that can be divided into two main categories: nonlymphoid and lymphoid. The most common nonlymphoid tumors are the vascular tumors, which include benign and malignant hemangiomas, lymphangiomas, and hemangioendotheliomas.

2014年7月23日 · Primary splenic angiosarcoma is the most common malignant nonhematolymphoid malignancy of the spleen. Lymphoma, myeloma, and metastases are the other malignant entities involving the spleen. The clinical presentation, key imaging findings, and associations of benign, neoplastic, and malignant diseases that can involve the spleen will be …

While some tumor and tumor-like lesions are unique to the spleen, others may also occur in diverse extra-splenic viscera. These tumors and tumor-like lesions demonstrate characteristic histopathology, immunocytochemistry and biological behavior.

2019年1月1日 · Tumors of the spleen are divided into either lymphoid or nonlymphoid types. Lymphoid tumors are mainly of the Hodgkin or non-Hodgkin variety. Nonlymphoid tumors, if primary, are most commonly of vascular origin and may be either benign or malignant.

Primary angiosarcoma is one of the extremely rare malignant vascular neoplasms of the spleen, which carries a dismal prognosis. It constitutes almost 7.4% of all primary malignant splenic neoplasms and is well known as an aggressive tumor with high local recurrence and distant metastasis rates.

Splenectomy is a feasible option but the tumour is seldom limited to the spleen. Prognosis is very poor in all cases. Haemangiosarcoma is a rare malignant tumour of vascular endothelial origin. It may be focal, locally invasive, cutaneous or disseminated.

5 天之前 · About two thirds of dogs that have a tumor on the spleen have a malignant form of cancer, and about two thirds of them are hemangiosarcoma (1). These tumors are more commonly found in Labradors, Goldens, Boxers, and German Shepherd Dogs. Unfortunately, they are aggressive and cause abnormal blood vessels, so they are likely to break open and ...

Tumors of the spleen are rare compared to the incidence of such tumors in other parenchymatous organs. Their classification has varied with both time and author. They can be divided into two main categories: nonlymphoid and lymphoid.

2024年11月10日 · Grayscale ultrasound of the spleen in a patient with hepatitis C (HCV) and previously treated hepatocellular carcinoma (HCC) shows a solitary solid mass in the spleen with central hyperechogenicity and peripheral hypoechogenicity (target-like pattern).

Splenomegaly is a very common finding and may result from numerous causes, usually grouped into 5 general etiologies, including congestion, hematologic, inflammatory-infectious, tumor, or infiltrative.
