Insights

Meckel scintigraphy identified a mobile focus, confirming a Meckel diverticulum in a child with abdominal pain. This imaging technique aids in diagnosing this congenital anomaly.

Area of Science:

  • Pediatric Gastroenterology
  • Nuclear Medicine Imaging
  • Surgical Diagnosis

Background:

  • Meckel diverticulum is a common congenital anomaly of the small intestine.
  • Intermittent abdominal pain and gastrointestinal bleeding are common symptoms in children.
  • Meckel scintigraphy is a key diagnostic tool for identifying ectopic gastric mucosa.

Observation:

  • An 11-year-old boy presented with abdominal pain and bloody stools.
  • Initial Meckel scintigraphy showed faint activity, evolving into distinct foci.
  • One focus demonstrated mobility, suggesting a Meckel diverticulum, while non-mobile foci correlated with a horseshoe kidney.

Findings:

  • Exploratory laparotomy confirmed the presence of a Meckel diverticulum.
  • The mobile focus on scintigraphy accurately represented the Meckel diverticulum.
  • Horseshoe kidney was incidentally identified and correlated with non-mobile activity.

Implications:

  • Meckel scintigraphy is valuable for diagnosing Meckel diverticulum, even with atypical presentations.
  • Differentiating mobile from non-mobile foci is crucial for accurate diagnosis.
  • This case highlights the importance of correlating imaging findings with surgical confirmation.

Kidney Structure01:45

Kidney Structure

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

External Anatomy of the Kidney01:21

External Anatomy of the Kidney

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Internal Anatomy of the Kidney

The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex
The outermost region of the kidney is the...

Kidney Transplant I: Introduction01:28

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
