A 26-year-old male patient with elevated serum parathyroid hormones and calcium secondary to intra-thyroid parathyroid adenoma. a, b Enhanced axial and coronal CT scan of the neck demonstrate a well-defined hypodense right thyroid nodule (white arrows). c Bone window coronal CT scan shows lytic expansile lesions at the right mandible and left ...
Features of benign lesion are: hyperechoic, having coarse, dysmorphic or curvilinear calcifications, comet tail artifact (reflection of a highly calcified object), absence of blood flow in the nodule, and presence of cystic (fluid-filled) nodule. However, the presence of solitary or multiple nodules is not a good predictor of malignancy.
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 ...
A CT scan shows both calcified and uncalcified cysts, as well as distinguishing active and inactive cysts. Cystic lesions can show ring enhancement and focal-enhancing lesions. Some cystic lesions, especially the ones in ventricles and subarachnoid space may not be visible on a CT scan, since the cyst fluid is isodense with cerebrospinal fluid ...
An epidermoid cyst or epidermal inclusion cyst [1] is a benign cyst usually found on the skin. The cyst develops out of ectodermal tissue. Histologically , it is made of a thin layer of squamous epithelium .
Sometimes a hypodense central area is seen instead of calcification. [25] When considering other potential intracranial masses in a differential diagnosis, such as cysticercosis , pyogenic abscess, and neoplastic lesions, tuberculoma can be identified by its larger size (>2 cm), edema, and irregular border.
Lesions are often classified by their tissue types or locations. For example, "skin lesions" or "brain lesion" are named for the tissue where they are found.If there is an added significance to regions within the tissue—such as in neural injuries where different locations correspond to different neurological deficits—they are further classified by location.
Cystic lesions of the pancreas are a group of pancreatic lesions characterized by a cystic appearance. They can be benign or malignant. [citation needed] Cystic lesions are found in 20.6% of all pancreatectomy specimens. Among this heterogeneous group, benign neoplasms predominate, particularly those with mucinous lining.
