Summary
High-resolution computed tomography (HRCT) reveals distinct patterns in herpes simplex virus (HSV) pneumonia, including ground-glass attenuation and consolidations. These findings aid in diagnosing HSV pneumonia in both immunocompromised and immunocompetent patients.
Area of Science:
- Radiology
- Pulmonology
- Infectious Diseases
Background:
- Herpes simplex virus (HSV) pneumonia is a rare but serious lower respiratory tract infection.
- Accurate diagnosis is crucial for timely and effective treatment.
Purpose of the Study:
- To evaluate the high-resolution computed tomographic (HRCT) findings in adult patients with herpes simplex virus (HSV) pneumonia.
- To identify characteristic HRCT patterns associated with HSV pneumonia.
Main Methods:
- Retrospective analysis of HRCT images from five adult patients diagnosed with HSV pneumonia.
- Correlation of HRCT findings with histopathological data (intranuclear inclusion bodies, immunohistochemical staining) when available.
- Assessment of parenchymal abnormalities including ground-glass attenuation, consolidation, nodules, and septal thickening.
Main Results:
- Three predominant HRCT patterns were identified: diffuse/multifocal ground-glass attenuation, multifocal peribronchial consolidations, or a mixed pattern.
- Ground-glass attenuation on HRCT corresponded to diffuse alveolar damage in one case.
- No significant HRCT finding differences were observed between immunocompromised and immunocompetent patients.
Conclusions:
- HRCT can reveal characteristic patterns in HSV pneumonia, including ground-glass attenuation and consolidations.
- HSV pneumonia should be considered in the differential diagnosis of acute lower respiratory infections with these HRCT findings, regardless of immune status.

01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:29Pneumonia II: Pathophysiology
The pathophysiology of pneumonia involves the following steps:
01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.

Pneumonia poses the potential for numerous complications that warrant consideration. These complications include the following:
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
