Summary
Small accessory liver lobes were found in 1.01% of patients, often in segment 6. These lobes showed varied imaging characteristics and some experienced size changes over time.
Area of Science:
- Radiology
- Gastroenterology
- Anatomy
Background:
- Accessory liver lobes are rare anatomical variations.
- Understanding their imaging features is crucial for accurate diagnosis.
Purpose of the Study:
- To determine the prevalence and morphometric features of small accessory liver lobes.
- To analyze their imaging characteristics on CT and MR.
Main Methods:
- Retrospective analysis of 3269 abdominal CT scans.
- Identification and characterization of small accessory liver lobes.
- Correlation with MR imaging where available.
Main Results:
- Prevalence of 1.01% (33/3269 patients) with 35 accessory lobes identified.
- Most frequent location: liver segment 6 (80.0%).
- Varied CT attenuation and enhancement patterns; MR showed T2 hyperintensity and variable enhancement.
Conclusions:
- Small accessory liver lobes are not uncommon and typically found in segment 6.
- Their imaging findings can differ from normal liver parenchyma.
- Morphological changes over time were observed in a significant proportion of lesions.

Accessory organs are those that participate in the digestion of food but do not come into direct contact with it like the mouth, stomach, or intestine do. Accessory organs secrete enzymes into the digestive tract to facilitate the breakdown of food.

The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

01:17Accessory Structures of the Eye
3.9K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

4.1K
The cytoskeleton is an essential cell component that plays several structural and functional roles. However, the filaments that make up the cytoskeleton cannot function independently and depend on the accessory or ancillary proteins to effectively carry out their function. Accessory proteins associate with cytoskeletal filaments and their monomers, aiding filament formation and function. They also help in the cross-communication among cytoskeletal filaments. Cytoskeletal accessory proteins are...

Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...
