Abstract:
The Epstein-Barr virus (also known as EBV), responsible for infectious mononucleosis, is a virus that infects the majority of the world's population. Infection occurs in several forms, most often asymptomatic, or as a fever accompanied by pharyngitis and lymphadenopathies. A rare complication of infectious mononucleosis is acute acalculous cholecystitis, an inflammation of the gallbladder characterized by ischaemia and severe cholestasis. The diagnosis of this pathology is made by imaging, but determining the cause may be tricky. We present here the case of acute acalculous cholecystitis in a 21-year-old woman. This case highlights a rare complication of EBV infection that is probably under-diagnosed, and demonstrates the usefulness of interpreting liver tests and leukocyte count in association with imaging findings.
Insights
Epstein-Barr virus (EBV) can cause a rare gallbladder inflammation called acute acalculous cholecystitis. Early diagnosis involves correlating imaging with liver function and white blood cell tests.
Area of Science:
- Virology
- Gastroenterology
- Hepatology
Background:
- Epstein-Barr virus (EBV) is a widespread herpesvirus, commonly causing infectious mononucleosis.
- Infectious mononucleosis typically presents asymptomatically or with fever, pharyngitis, and lymphadenopathy.
- Acute acalculous cholecystitis is a rare gallbladder inflammation without gallstones, often linked to ischemia and cholestasis.
Observation:
- A case study of a 21-year-old woman presenting with acute acalculous cholecystitis is detailed.
- The patient's presentation highlights a less common manifestation of EBV infection.
- Diagnostic challenges in determining the etiology of acute acalculous cholecystitis are noted.
Findings:
- The case underscores acute acalculous cholecystitis as a rare complication of Epstein-Barr virus infection.
- Interpreting liver function tests and leukocyte counts alongside imaging is crucial for diagnosis.
- EBV-associated cholecystitis may be an under-recognized clinical entity.
Implications:
- This case emphasizes the importance of considering EBV in the differential diagnosis of acute acalculous cholecystitis.
- Clinicians should integrate laboratory findings with imaging to improve diagnostic accuracy for this rare complication.
- Further research may elucidate the mechanisms and prevalence of EBV-induced gallbladder inflammation.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
Acute Pancreatitis II: Clinical Manifestations and Management
Chronic Bowel Disorders: Introduction
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...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
