"Pulmonary hyalinizing granuloma" is a lesion characterized by keloid-like fibrosis in the lung and is not granulomatous. Similarly, radiologists often use the term granuloma when they see a calcified nodule on X-ray or CT scan of the chest. They make this assumption since granulomas usually contain calcium, although the cells that form a ...
It is a small area of granulomatous inflammation, only detectable by chest X-ray if it calcifies or grows substantially (see tuberculosis radiology). [2] Typically these will heal, but in some cases, especially in immunosuppressed patients, it will progress to miliary tuberculosis (so named due to the granulomas resembling millet seeds on a ...
Gandy–Gamna nodules or Gandy-Gamna bodies, sometimes known as Gamna-Gandy bodies or Gamna-Gandy nodules, are small yellow-brown, brown, or rust-colored foci found in the spleen in patients with splenomegaly due to portal hypertension, [1] as well as sickle cell disease.
Chest x-ray of Ghon's complex of active tuberculosis. Ghon's complex is a lesion seen in the lung that is caused by tuberculosis. [1] [2] The lesions consist of a Ghon focus along with pulmonary lymphadenopathy within a nearby pulmonary lymph node.
Splenomegaly is an enlargement of the spleen. [1] The spleen usually lies in the left upper quadrant (LUQ) of the human abdomen.Splenomegaly is one of the four cardinal signs of hypersplenism which include: some reduction in number of circulating blood cells affecting granulocytes, erythrocytes or platelets in any combination; a compensatory proliferative response in the bone marrow; and the ...
A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. [1] Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles.
Calcification can manifest itself in many ways in the body depending on the location. In the pulpal structure of a tooth, calcification often presents asymptomatically, and is diagnosed as an incidental finding during radiographic interpretation. Individual teeth with calcified pulp will typically respond negatively to vitality testing; te
These granulomas are the main reason for the name granulomatosis with polyangiitis, although it is not an essential feature. Nevertheless, necrotizing granulomas are a hallmark of this disease. However, many biopsies can be nonspecific and 50% provide too little information for the diagnosis of GPA. [12]
