A "lobulated" adenocarcinoma of the lung. A lobulation is an appearance resembling lobules. For instance, the thyroid gland may become large and lobulated in Hashimoto's thyroiditis. [1] Fetal lobulation, also known as fetal lobation, of the kidney is evident on scanning. Fetal lobation is a normal stage in the development of the kidney. [2]
A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules.
Diagnosis usually by CT showing lobulated mass. Confirmation done by tissue biopsy of accompanying nodes if any, mediastinoscopy, mediastinotomy, or thoracotomy. FNA biopsy is usually not adequate. Treatment of mediastinal Hodgkin's involves chemotherapy and/or radiation. 5 year survival is now around 75%.
Clinically, the lesion is observed as a hard, well-circumscribed, lobulated, round to oval, or fibrous mass that has a sparkling gray-to-white aspect and appears fibrous on the cut surface. [3] Patients with these tumors often appear with a history of a painless, slowly developing mass, often over a reasonably lengthy period of time.
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
The lesion is usually symmetric, well demarcated, erythematous and depapillated, which has a smooth, shiny surface. Less typically, the lesion may be hyperplastic or lobulated and exophytic. There may be candidal lesions at other sites in the mouth, which may lead to a diagnosis of chronic multifocal oral candidiasis. Sometimes an approximating ...
The kidneys in mammals are usually bean-shaped [4] or externally lobulated. [5] They are located behind the peritoneum ( retroperitoneally ) [ 6 ] on the back ( dorsal ) wall of the body. [ 7 ] The typical mammalian kidney consists of a renal capsule , a peripheral cortex , an internal medulla , one or more renal calyces , and a renal pelvis ...
Signs and symptoms of liver masses vary from being asymptomatic to patients presenting with an abdominal mass, hepatomegaly, abdominal pain, jaundice, or some other liver dysfunction. Treatment varies and is highly specific to the type of liver tumor. [3]
