Splenic lymphangioma Radiology

Cystic lymphangioma of the spleen is a very rare condition and is usually solitary and asymptomatic. Large lymphangiomas may be an indication for splenectomy, since the risk of rupture is high even from minor abdominal trauma. Preoperative diagnosis may be achieved with correlated noninvasive imaging Splenic lymphoma, also termed as lymphomatous involvement of the spleen, represents the most common malignancy to involve the spleen. They are commonly secondary, rarely being primary (referred as primary splenic lymphoma) Lymphangiomas are benign lesions of vascular origin that show lymphatic differentiation. They occur in many anatomic locations and may have a pediatric or adult clinical presentation. Most (95%) occur in the neck and axillary regions; the remaining 5% are located in the mesentery, retroperitoneum, abdominal viscera, lung, and mediastinum [ 1 ] Morphologically, lymphangiomas are classified into three subtypes: simple, cavernous and cystic. Most of the cases of splenic lymphangioma reported in the literature are of cystic subtype. In the present case, in addition to the cysts, there were frequent areas of spongy appearance Splenic lymphangiomas are exceedingly rare benign neoplasms that occur mainly in children. They are commonly seen in the neck and axillary region. Abdominal lymphangiomas accounts for less than 5% of cases. So far, fewer than 100 cases of spleen lymphangiomas have been reported in the literature

Cystic lymphangioma of the spleen: US-CT-MRI correlatio

  1. Many focal splenic lesions may appear to be cystic at cross-sectional imaging. In this article, the following types of cystic splenic masses are discussed: congenital (true cyst), inflammatory (abscesses, hydatid cyst), vascular (infarction, peliosis), posttraumatic (hematoma, false cyst), and neoplastic (hemangioma, lymphangioma, lymphoma, metastasis)
  2. Lymphoma is the commonest malignant tumor of the spleen. It is important to detect splenic involvement because it can alter the management. Lymphomatous deposits have T1 and T2 similar to those of normal splenic parenchyma. Gadolinium-enhanced sequences are more sensitive for the evaluation of splenic lymphoma
  3. The spleen is an encapsulated organ composed of vascular sinuses, which comprise the red pulp, and interspersed cords of lymphatic tissue, making up the white pulp. 2 CT imaging demonstrates heterogeneous splenic enhancement on arterial phase imaging, due to variation in blood flow through the sinuses and cords. In the portal venous phase.
  4. splenic mass detected in an asymptomatic patient is anincidental lesion that poses a diagnostic dilemma. Thetypical incidentally discovered splenic mass is a solid ormostly solid lesion that is hypoattenuating on CT, lowsignal intensity on T1-weighted images, and intermedi-ate to mildly increased signal intensity on T2-weighte
  5. Splenic lymphangioma is a rare malformation of the splenic lymphatic channels, mostly seen in children. It is characterized by the presence of cysts, resulting from increases in the size and number of thin-walled lymphatic vessels that are abnormally interconnected and dilated
  6. Splenic lymphangiomas are rare benign tumors occurring more frequently in children. Because of their asymptomatic growth, splenic lymphangiomas are usually suspected based on incidental findings, the diagnosis relying on different imaging techniques and requiring histological confirmation

Author information: (1)Department of Radiology, Urmia University of Medical Sciences, Urmia, West-Azerbaijan, Iran. mohamadi_afshin@yahoo.com Developmental malformation of the lymphatic system and cystic proliferation of lymphatic. Background and methods: We tried to determine the role and problems of gray-scale sonography (US), computed tomography (CT), and color Doppler sonography in the diagnosis of splenic lymphangioma on the basis of our experience with seven adult cases with this relatively rare tumor. Results: (1) The whole spleen was replaced by a collection of cysts of different sizes with or without. 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 discussed All in all, a splenic lymphangioma is a very seldom illness. Aside from the casuistics in children, isolated splenic lymphangiomas are described mostly in adults. A lymphangiomatosis, which is described often in literature, could not be found in our patient

Splenic lymphangioma: A rare adult case with imaging

The splenic parenchyma consists of lymphatic follicles and reticuloendothelial cells, surrounding the arteries ('white pulp') and an interspersed network of vascular sinusoids ('red pulp'). (1) The ratio of white to red pulp increases with age due to accumulated antigenic exposure and stimulation Hemangiomas are the most common primary benign splenic neoplasms. Incidental hemangiomas generally measure <2 cm and commonly occur in the 30-50 years of age. Hemangiomas can be associated with angiomatosis syndromes such as Kasabach-Merritt syndrome, which consists of anemia, thrombocytopenia, and coagulopathy Isolated splenic lymphangioma is extremely rare; since the first description of a patient with splenic involvement in 1885 by Frink et al., a few cases have been reported in the literature [1,2,3]. The disease is often suspected incidentally on the basis of imaging or very rarely in symptomatic patients with abdominal pain or distension [ 2 ] Lymphangioma, a congenital malformation of the lymphatic system, is usually found in children, and generally occurs in the neck and mediastinum. It is rarely found in the spleen. The clinical features of splenic lymphangioma typically include abdominal pain, nausea, and abdominal distention Cross-Sectional Imaging of the Spleen.

Splenic lymphangioma: A rare adult case with imaging features J. Gonçalves Júnior Case reportA 59-year-old female patient reported that for around a year, she had been feeling unwell, with postprandial fullness and diffuse abdominal pain, particularly in the epigastrium and hypochondrium, without other complaints and/or clinical intercurrences Splenic lymphangiomas are rare benign tumors occurring more frequently in children. Because of their asymptomatic growth, splenic lymphangiomas are usually suspected based on incidental findings, the diagnosis relying on different imaging techniques and requiring histological confirmation. The rarity of the disease and its atypical imaging findings make the diagnosis of splenic lymphangiomas. Generalized lymphatic anomaly is a rare multisystem congenital disorder in which multiple organs are involved. Imaging features often overlap with other complex lymphatic anomalies and diagnosis is difficult. Treatment options are limited, not remedial and prognosis is poor. We report a 12-year-old male who presented with axillary and chest wall lymphangioma but was subsequently diagnosed as. Solitary lymphangioma of the spleen is an extremely rare, benign vasoformative tumour that typically shows no notable enhancement on imaging studies. Few descriptions of the MRI features have been reported and, to our knowledge, the findings on dynamic gadolinium-enhanced MR images have never been described

It is characterized by the presence of cysts, resulting from increases in the size and number of thin-walled lymphatic vessels that are abnormally interconnected and dilated spleen; splenic mass; ultrasonography; Focal lesions in the spleen are rare as compared with those in other solid viscera. The focal masses can be delineated by ultrasonography, computed tomography, radionuclide studies, and magnetic resonance imaging.1-4 Reports of a large series regarding focal splenic lesions by cross sectional imaging and ultrasonography are rare.1-3 5-

Similar case reports of cystic lymphangioma of spleen in the literature are illustrated in the table 1.19-23 Wahab, et al18 reported three cases of lymphangiomatous cysts of the spleen in the year 1998, and Kim, et al24 reported three cases of splenic lymphangioma in 2002. Learning points Rare congenital malformation of the lymphatic system Furthermore, splenic volume varies greatly from one individual to another. Normal in vivo adult splenic volume ranges from 107 to 314 cm 3. A quick quantitative assessment of splenic size can be made on imaging on CT using splenic index, i.e. the product of the length, width and thickness. The normal splenic index is between 120-480 cm 3 Based on the findings, malignancy cannot be excluded. Then, pathologic examination was performed, and it was identified to be splenic lymphangioma. We herein presented the FDG PET/CT findings of this splenic lymphangioma, which is a rare benign vascular tumor and commonly caused by congenital malformation of the lymphatic vessels Lymphangioma is a benign lesion of vascular origin. Most lymphangiomas are located in the neck, but 5% of lymphangiomas are abdominal. Lymphangioma has enhancing septa. Unlike in cystic peritoneal metastases, ascites is not a feature of lymphangioma. When you see a septated cystic lesion without ascites the most likely diagnosis is a lymphangioma

Primary splenic lymphoma is defined when only spleen and perisplenic lymph nodes are involved. Splenic appearance in lymphoma is normal, splenomegaly, focal or multifocal appearance [2,6,7]. Primary splenic lymphoma shows hypointensity on T1WI, variable signal on T2WI, and hypovascular behavior regarding parenchyma on MRI As the largest single lymphatic organ in the human body, the spleen is responsible for central immunological and haematological tasks. Therefore, the spleen can be subject to a wide range of pathologic disorders. Computed tomography (CT) represents the most widely applied cross-sectional abdominal imaging technique and is considered the imaging modality of choice for the evaluation of numerous. Pancreaticoduodenal lymph nodes were identified in 55%, splenic lymph nodes in 55%, gastric lymph nodes in 20% and hepatic lymph nodes in 5% of the 20 ferrets (Garcia et al. 2011). Lymph nodes were described as circular to elongate, hypoechoic structures surrounded by fat; some lymph nodes also had a faint echogenic halo The American Association for the Surgery of Trauma (AAST) is the most widely used grading system for splenic trauma; imaging features are the basis of the grading system. Splenic trauma is usually associated with overlying rib fractures. A splenic infarct characteristically presents on CT as a peripheral wedge-shaped hypodense lesion Purpose This study sought to characterize the imaging features of primary splenic lymphoma (PSL). Materials and Methods Pathological and imaging data from 17 patients with primary splenic lymphoma initially diagnosed at splenectomy were retrospectively analyzed. Pretreatment computed tomography (CT) imaging was available for 16 patients, and magnetic resonance imaging (MRI) data were available.

of solitary metastases in the posterior third of the spleen. CECT is the imaging modality of choice for conditions affecting the spleen.[2] The majority of solitary splenic lesions identified with CECT are of primary splenic origin, eg, hemangioma, lymphoma, hematoma, abscess, and infarction. However, i Non-Hodgkin and Hodgkin lymphomas frequently involve many structures in the abdomen and pelvis. Extranodal disease is more common with Non-Hodgkin's lymphoma than with Hodgkin's lymphoma. Though it may be part of a systemic lymphoma, single onset of nodal lymphoma is not rare. Extranodal lymphoma has been described in virtually every organ and tissue. In decreasing order of frequency.

Anatomy. The spleen is a dynamic falciform organ usually residing in the left cranial quadrant of the abdomen. It has been described as red, reddish-brown, purple, mahogany, and gray-brown with a purple cast. 21,22,29 A normal spleen is soft and yielding in consistency but not as friable as the liver and is approximately 0.2% of the body weight in dogs and cats. 29 The dorsal extremity (head. In adults, the spleen is a purple organ that is about the size of a clenched fist. It's covered in visceral peritoneum, a smooth membrane that's composed of two layers of cells, which secrete fluid and serve a protective function. 1  There is, however, an opening in this membrane called the hilum of the spleen, which allows the splenic.

Physiologic EMH. During fetal development, hematopoiesis occurs mainly in the fetal liver and in the spleen followed by localization to the bone marrow. Hematopoiesis also takes place in many other tissues or organs such as the yolk sac, the aorta-gonad mesonephros (AGM) region, the spleen, and lymph nodes.During development, vertebrates go through a primitive and a definitive phase of. MALIGNANT SPLENIC DISEASE. Lymphoma is the most common malignant disease affecting the spleen. Lymphomas comprise a number of diseases, all malignant, which affect the lymphocytes.
