Summary
Gallbladder adenomyomatosis, a benign condition, caused chronic abdominal pain in a 50-year-old male. Imaging revealed characteristic signs, confirmed by surgery, leading to a full recovery.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Pathology
Background:
- Gallbladder adenomyomatosis is a benign proliferative disease of the gallbladder wall.
- It can present with vague abdominal symptoms, mimicking other gastrointestinal conditions.
Observation:
- A 50-year-old male presented with a six-year history of right upper quadrant abdominal pain, nausea, and early satiety.
- Initial blood tests were unremarkable.
- Abdominal CT revealed concentric segmental mural thickening of the gallbladder with intramural cystic foci (rosary sign).
Findings:
- Abdominal MRI demonstrated segmental gallbladder mural thickening with fluid-filled intramural diverticula (pearl necklace sign) and an hourglass gallbladder configuration.
- These imaging findings were consistent with segmental gallbladder adenomyomatosis.
- Laparoscopic cholecystectomy confirmed the diagnosis of gallbladder adenomyomatosis, with no evidence of malignancy.
Implications:
- Gallbladder adenomyomatosis can be diagnosed non-invasively using CT and MRI.
- Surgical management, such as cholecystectomy, provides definitive diagnosis and symptom relief.
- This case highlights the importance of considering adenomyomatosis in the differential diagnosis of chronic gallbladder-related symptoms.

1.5K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

01:24Chronic Pancreatitis I: Introduction
533
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

541
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
