    Accessory spleens are common, usually asymptomatic, incidentally discovered congenital foci of splenic tissue. They occur most commonly near the splenic hilum, with almost 20% in or near the pancreatic tail. On contrast-enhanced computed tomography (CT), differentiation of an intrapancreatic accessory splenule (IPAS) from other pancreatic tail lesions such as islet cell tumors and metastatic disease can present a diagnostic challenge. A high index of suspicion on the part of the radiologist, based on the classic location with typical imaging features and a combination of cross-sectional imaging studies such as ultrasound, computed tomograph (CT), or magnetic resonance imaging (MRI) with nuclear medicine examinations, can confirm the diagnosis of intrapancreatic accessory splenule and prevent unnecessary biopsy and/or surgery.

    Pancreas01:19

    Pancreas

    The pancreas, an essential organ in the human body, is a pinkish-gray elongated structure located posterior to the stomach. It extends laterally from the duodenum towards the spleen and is firmly bound to the posterior wall of the abdominal cavity. The organ's surface has a lumpy, lobular texture that gives it a unique appearance.
    The broad head of the pancreas lies within the loop formed by the duodenum, while its slender body reaches towards the spleen. The tail of the pancreas is short...

    Accessory Organs01:31

    Accessory Organs

    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.

    Blood Supply to the Digestive System01:16

    Blood Supply to the Digestive System

    Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
    Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

    Pancreatic Juice and Secretion01:26

    Pancreatic Juice and Secretion

    Pancreatic juice is a clear fluid produced by the pancreas, containing water, salts, sodium bicarbonate, and enzymes vital for digestion in the small intestine. It helps break down large molecules, facilitating nutrient absorption.
    When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...

    Abdominal Aorta01:25

    Abdominal Aorta

    Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
    The celiac trunk, a singular artery, divides into the left gastric artery, which...

    Cells and Secretions of the Pancreas01:16

    Cells and Secretions of the Pancreas

    The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
    Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
    Concurrently, the dispersed clusters of endocrine cells throughout the...
