Insights

Melioidosis, a severe bacterial infection caused by Burkholderia pseudomallei, can affect multiple organs. Radiological imaging aids diagnosis, with a "honeycomb" liver abscess appearance being characteristic.

Area of Science:

  • Infectious Diseases
  • Radiology
  • Microbiology

Background:

  • Melioidosis is a severe, often fatal infection caused by Burkholderia pseudomallei, an environmental bacterium.
  • It is endemic in Southeast Asia and Northern Australia but increasingly reported globally.
  • The infection can affect virtually any organ system.

Purpose of the Study:

  • To describe the diverse radiological manifestations of melioidosis across various organs.
  • To enhance awareness among clinicians regarding imaging findings to facilitate early diagnosis.
  • To highlight the importance of radiological imaging in the diagnostic workup of melioidosis.

Main Methods:

  • This pictorial essay reviews radiological findings from confirmed melioidosis cases.
  • It includes imaging examples of melioidosis affecting multiple organ systems.
  • The focus is on characteristic and suggestive imaging features.

Main Results:

  • Melioidosis can present with varied radiological findings, often without pathognomonic signs.
  • Simultaneous involvement of multiple organs is a common characteristic.
  • A "honeycomb" appearance in large liver abscesses is a distinctive feature.

Conclusions:

  • Radiological imaging is crucial for diagnosing melioidosis and guiding treatment.
  • Familiarity with melioidosis's diverse imaging spectrum aids in early detection.
  • While not always specific, certain findings like "honeycomb" liver abscesses are highly suggestive.

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Pulmonary Tuberculosis IV01:26

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
