Subcontractor Agreement Basics. Whether you're a subcontractor or just hiring one, a subcontractor agreement helps protect both your interests. As an agreement between a general contractor and a subcontractor, it describes the services and materials provided by the subcontractor, price of the work, and warranties of the parties. Other important clauses include insurance, default, change orders, and indemnification.
A subcortical heterotopia may appear to have mass effect on the adjacent ventricle, so it is important to use imaging clues, such as lack of enhancement, isointense signal to gray matter, lack of associated edema, and diminished volume in the affected region of brain, to differentiate this entity from tumor.
Lipomas - Pathophysiology. 1  Lipomas are common benign mesenchymal tumors. 2  In the GI tract, lipomas present as submucosal fatty tumors. 3  Duodenal lipomas are mostly small but may become pedunculated with obstruction of the lumen. 4  Colonic lipomas are usually discovered on endoscopy. Gentle palpation with a biopsy forceps reveals the soft nature of the submucosal mass. A biopsy specimen of the mucosa may reveal underlying fat, the so-called naked fat sign. As with lipomas in other locations, colonic lipomas may cause pain with obstruction or intussusception. As noted above, a fatty protrusion of preperitoneal fat termed a lipoma of the spermatic cord is a common finding on groin exploration for hernia repair.
