Steatosis in the liver can be present in either a microvesicular or a macrovesicular pattern. When assessing configuration, note the following characteristics: Note if the lesion(s) is/are discrete or confluent. Configuration (the pattern or shape of grouped lesions) Terms Meaning Discrete Individual lesions separated from each other Confluent Lesions merging together Linear In a line Target Concentric rings (like a dartboard) Example: Annular Like a circle or ring Example: Discoid / A coin-shaped/round lesion Nummular Example: Lee, in Pathobiology of Human Disease, 2014 Steatohepatitis. Macrovesicular steatosis is the most common form and is histologically characterized by hepatocytes containing a single vacuole of fat filling up the hepatocyte and displacing the nucleus to the cell's periphery. 2. This has been termed a “moth-eaten” pattern. Rather than a single discrete lesion, we may see several ill-defined foci of lucency. Its prevalence varies from 0.5-3% of the US population.

MRI lesion prevalence in community-dwelling elderly was reported to range from 5.3% to 100%, depending on study design, study population, and assessment method (1–5). They usually present in the elderly, with a mean age of 65 years 7.There may be a slight male predilection. Multiple sclerosis (MS) is a common central nervous system (CNS) disease characterised pathologically by the development of multifocal inflammatory demyelinating white matter lesions. The centre of the lesions may be vesicular, purpuric or necrotic. aseptic necrosis necrosis without infection or inflammation. Stevens-Johnson syndrome - involves a rash that can begin as macules that develop into papules, vesicles, bullae, urticarial plaques or confluent erythema. Numerous pale pink, almond-shaped macules appear on the trunk and neck. If the lesion grows more rapidly still, there may not be time for the bone to retreat in an orderly manner, and the margin may become ill-defined. Epidemiology. 1.

All submissions are peer reviewed. Myxoid pattern may predominate and simulate myxoid liposarcoma. The presence of invasion rules out an endometrial stromal nodule (answer B) and cellular leiomyoma (answer A). If the lesion grows more rapidly still, there may not be time for the bone to retreat in an orderly manner, and the margin may become ill-defined. Confluent generalized lesions also may occur. Other, less common, possible causes of an ulcer are infective (bacterial or fungal) and immune-related causes (eg … Morens DM, Katz AR. Ulcerations are characterized by defects in the epithelium, underlying connective tissue, or both. Apica, W.M. Computed Tomography. The imaging appearance of a metastatic lesion in the spleen varies with the type of primary cancer [38, 39]. Many rash illnesses can present with vesicles and pustules. Assess the border of the lesion(s) (e.g. Although the cause of hair loss is easily diagnosed in some cases, such as in patients who present with classic male pattern hair loss or patchy hair loss due to alopecia areata, the diagnosis of hair loss also can be challenging. Note the shape of the lesion(s). ... has coalesced to form a conglomerate lesion (macronodule). 4. The typical appearance is a hypoattenuating lesion with occasional calcifications and mild enhancement , which may be associated with splenomegaly . Lesion shows type II hydatid cyst pattern, hypodense hepatic lesion with peripherally arranged daughter cysts with curvilinear wall calcification (arrow), as seen on CT image. A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, hair, nails, and related muscle and glands. Am J Epidemiol. The pattern of multiple lesions or the shape of an individual lesion can be useful in narrowing the differential diagnosis. Since these lesions have increased glandular density, they can simulate AEH/EIN. Confluent generalized lesions also may occur. References: 1.

Multiple sclerosis is an inflammatory demyelinating disease of the CNS in which activated immune cells invade the central nervous system and cause inflammation, neurodegeneration, and tissue damage.The underlying cause is currently unknown. Confluent nodular opacities that appear on high-resolution CT images as bilateral areas of lung. The pattern of individual skin lesions is also important to describe, they may be solitary, grouped or a satellite lesion with a clustered group surrounding. Autoimmune encephalitis is an important cause of new-onset altered mental status, the scope of which has only recently begun to be recognized in the medical literature.

Due to diversity of causative factors and presenting features, diagnosis of oral ulcerative lesions might be quite challenging [1–4].This narrative review paper, however, focuses on the duration and the number of lesions in order to build a diagnostic decision tree. Confluent and reticulated papillomatosis (CARP), also called confluent and reticulated papillomatosis of Gougerot and Carteaud, is an uncommon skin condition that consists of multiple small, hyperkeratotic macules or papules that coalesce to form patches or plaques with a reticulated (net-like) pattern … The tumor shows a polypoid component, as well as a characteristic permeative tongue-like invasion pattern seen on low power. If a skin lesion is clinically suspicious of lentigo maligna, it is best cut out (excision biopsy) with a 2–3 mm margin. The "fourth disease" of childhood: reevaluation of a nonexistent disease.

Normal retroperitoneal lymph nodes are either invisible or appear on CT as small round or oval densities less than 1 cm in diameter (Fig. An ulcerated lesion is most commonly traumatic or immunological (aphthous) in origin; however, the most important lesion to exclude is an oral malignancy. The next stage in a skin examination is to describe the individual lesion or lesions, which are also referred to as primary lesions. Diseases that present with fever and rash are usually classified according to the morphology of the primary lesion… Partial biopsy is less accurate than complete excision biopsy, as a single small biopsy could miss a malignant focus.
