Fat-containing liver lesions: a pictorial review

<div><p>Abstract The aim of this pictorial essay is to review the spectrum of fat-containing liver lesions and their characterisation on magnetic resonance imaging with focus on the radiological features that aid in the differential diagnoses. Fat-containing liver lesions comprise a heterogeneous group of tumours with variable imaging findings. Magnetic resonance imaging clearly displays the micro- and macroscopic fat components of the lesions and other characteristic features that are helpful tools to make the differential diagnosis.</p></div

Histopathological analysis of lung sections from fatal dengue cases (a, b, c), stained with hematoxylin and eosin, showed pulmonary alterations, including alveolar septal thickening, hyaline membrane formation (HM), hemorrhage (He), edema (E), and the presence of type II pneumocytes (PcyII).

Skeletonization process of the trachea.

<p>Three-dimensional reconstruction of the trachea of one study participant in two planes (A and B). The median values showed in the ten planes of square cross-sections are as follows: area = 184.5 mm²; perimeter = 47.6 mm; eccentricity = 0.51; equivalent diameter = 15.3 mm; major diameter = 15.9 mm; minor diameter = 14.4 mm; and tortuosity = 1.027.</p

Measurement of the tortuosity of the trachea.

<p>Images in the coronal (A) and sagittal (B) planes are shown. In this scheme, <i>L</i> is the length of the trachea (the total length of 'ab', shown in blue) and <i>vd</i> is the vectorial distance between the points at the extremities (the length of the shortest possible path between 'a’ and ‘b', shown in red).</p

Relationship between forced vital capacity (FVC) and eccentricity of the trachea (r = -0.57, p = 0.002).

<p>Scleroderma group (1) = scleroderma group with no pulmonary involvement/limited interstitial lung disease; scleroderma group (2) = scleroderma group with extensive interstitial lung disease.</p

A 30-year-old woman with a confirmed diagnosis of dengue and respiratory failure requiring non-invasive ventilation.

<p>CT image acquired 6 days after the onset of clinical symptoms (a) shows interlobular septal thickening, mild ill-defined ground-glass opacities, and peribronchovascular interstitial thickening. Bilateral pleural effusion is also present. Complete resolution of the parenchymal abnormalities was observed on a CT images (b) obtained 7 days later.</p
