Abdominal splenosis and its differential diagnoses: What the radiologist needs to know
2021
Abstract Splenosis is a benign acquired condition characterized by the presence of heterotopic viable splenic tissue in other organs or within cavities such as peritoneum, retroperitoneum, or thorax after splenic trauma or surgery. Abdominal splenosis is often an incidental finding and computed tomography and magnetic resonance usually allow a confident diagnosis. The typical enhancement that parallels the spleen is a useful hallmark of splenosis. Splenic implants lack contrast uptake in the hepatobiliary phase and show high signal at high b-values on diffusion-weighted images. In some cases splenosis may mimic malignant and benign conditions in the peritoneum as well as in hollow and paren…
Respiratory GAS Exchange and pO2- Distribution in Splenic Tissue
1973
Little attention has been paid to physiological aspects of O2 supply to splenic tissue. Studies are performed to examine the factors determining the supply conditions for the rabbit’s spleen, which has little reservoir function and, therefore, it is very similar to the human spleen. Previous studies on respiratory gas exchange, applying the arterial and spleno-venous blood gas values, have shown a mean arterio-venous O2-difference of 0.5 Vol.% (2). Taking into account a mean splenic blood flow of 110 ml/100g/min (12), the O2 consumption of splenic tissue amounts to 0.6 ml/100g/min.
Splenic respiratory gas exchange and glucose uptake in patients with splenomegaly in hypersplenism and Hodgkin's disease.
1977
Blood samples are taken from the splenic artery, vein and pulp of patients suffering from Hodgkin's disease (n=10) or hypersplenism (n=7) and undergoing splenectomy. In these samples, the relevant parameters of the respiratory gas exchange as well as glucose and lactate concentrations are determined. In hypersplenism (mean splenic wet weight: 543 g) the mean oxygen consumption of the splenic tissue amounts to 0.9 ml O2/100 g/min taking into account a mean splenic blood flow of 80 ml/100 g/min. The glucose uptake and the lactate release are 9 mg/100 g/min and 5.5 mg/100 g/min, respectively. These values are in close agreement with the results obtained in the normal and undisturbed spleen in …
