Summary
Heat stroke, a severe condition causing high body temperature and brain issues, can lead to specific brain lesions. This study highlights two cases of heat stroke with symmetrical damage in the dentate nuclei and cerebellar peduncles.
Area of Science:
- Neurology
- Radiology
- Emergency Medicine
Background:
- Heat stroke (HS) is a critical medical emergency defined by severe hyperthermia and central nervous system (CNS) dysfunction.
- Prompt recognition and diagnosis of HS are crucial for patient outcomes.
Observation:
- This report details two unique cases of heat stroke.
- Both cases exhibited symmetrical brain lesions specifically in the dentate nuclei and cerebellar peduncles.
Findings:
- Magnetic resonance imaging (MRI) revealed characteristic features of these lesions.
- Proton magnetic resonance spectroscopy ((1)H-MRS) provided further insights into the metabolic changes within the affected brain areas.
- Follow-up imaging studies demonstrated the evolution of these characteristic MRI and (1)H-MRS findings.
Implications:
- Understanding these specific neuroimaging patterns aids in diagnosing heat stroke.
- This case series may improve the recognition of HS-related brain injury on MRI and (1)H-MRS.
- Further research into the pathophysiology of these lesions could inform treatment strategies for heat stroke.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

7.7K
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

4.4K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
