Insights

Choledochal cysts, common in East Asia, can cause rare vitamin K deficiency bleeding in infants. This case highlights a choledochal cyst presenting as intracranial hemorrhage in a 2-month-old infant.

Area of Science:

  • Pediatric Surgery
  • Neonatal Medicine
  • Gastroenterology

Background:

  • Choledochal cysts are congenital dilations of the bile ducts, more prevalent in East Asian populations.
  • Typical symptoms include abdominal pain, jaundice, and palpable abdominal masses.
  • While a known cause of neonatal cholestasis, their association with severe bleeding disorders is infrequent.

Observation:

  • A 2-month-old infant presented with partial coma and right subdural hemorrhage.
  • Preoperative evaluation revealed a significant coagulopathy.
  • Abdominal imaging identified an underlying choledochal cyst.

Findings:

  • The infant's intracranial hemorrhage was linked to a vitamin K deficiency bleeding disorder.
  • This bleeding disorder was secondary to the choledochal cyst, a rare presentation.
  • Successful management involved correcting the coagulopathy and surgical intervention for the cyst.

Implications:

  • This case underscores the importance of considering choledochal cysts in infants with unexplained bleeding, even without classic symptoms.
  • Early diagnosis and management of choledochal cysts can prevent life-threatening complications like intracranial hemorrhage.
  • Highlights a rare but critical differential diagnosis in neonatal intracranial hemorrhage.

Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

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...
