Summary
Half of tuberculous meningitis patients show MR angiography abnormalities, often linked to infarcts. Early detection through MRA is crucial for managing TBM complications.
Area of Science:
- Neurology
- Radiology
- Infectious Diseases
Background:
- Tuberculous meningitis (TBM) frequently causes infarcts, yet MR angiography (MRA) data is limited.
- Understanding MRA patterns in TBM is essential for diagnosis and management.
Purpose of the Study:
- To investigate the characteristics of MRA abnormalities in TBM patients.
- To identify predictors associated with MRA findings in TBM.
Main Methods:
- Sixty-seven TBM patients underwent clinical, laboratory, MRI, and MRA assessments.
- MRA evaluated intracranial arteries (MCA, ACA, PCA, basilar) for occlusion or stenosis >50%.
- Abnormalities were correlated with clinical, lab, and MRI findings, including exudates, hydrocephalus, tuberculoma, and infarction.
Main Results:
- 50.7% of TBM patients exhibited MRA abnormalities, predominantly in the MCA, PCA, and ICA.
- MRA abnormalities correlated with hydrocephalus and infarction.
- 61.8% of patients with abnormal MRA had corresponding infarcts, with 41.7% developing new infarcts at 3 months.
Conclusions:
- MRA abnormalities are common in TBM, affecting both anterior and posterior circulations.
- MRA findings are associated with infarct development in TBM patients.
- MRA is a valuable tool for assessing cerebrovascular complications in TBM.

01:26Pulmonary 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...

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...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
