Simple renal cyst. A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy.
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Either empirical antiviral or antifungal therapy or both should be considered. In addition to infections due to neutropenia, a patient with the Acute Radiation Syndrome will also be at risk for viral, fungal and parasitic infections. If these types of infection are suspected, cultures should be performed and appropriate medication started if ...
Acute radiation proctitis — symptoms occur in the first 3 months after therapy. [4] These symptoms include diarrhea and the urgent need to defecate. Radiation associated vascular ectasias (RAVE) and chronic radiation proctopathy — previously known as "chronic radiation proctitis" occur 3-6 months after the initial exposure. RAVE is ...
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
Radiation is rare, but may be used if a tumor is involved. In these cases, it can halt the extension of a cavity and may help to alleviate pain. [31] Treatment is usually reserved for cases which are causing symptoms. Treatment may not provide enough benefits to be recommended for elderly patients, or when symptoms are stable instead of worsening.
Cysts cause posterior enhancement as a consequence of reduced attenuation of the ultrasound within the cyst fluid (Figure 5). The simple cyst is a benign lesion, which does not require further evaluation. [1] Complex cysts can have membranes dividing the fluid-filled center with internal echoes, calcifications or irregular thickened walls.
Early radiation enteropathy is very common during or immediately after the course of radiotherapy. This involves cell death, mucosal inflammation and epithelial barrier dysfunction. This injury is termed mucositis and results in symptoms of nausea, vomiting, fatigue, diarrhea and abdominal pain. [1] [6] It recovers within a few weeks or months.
