Exploring Transverse Myelitis Radiology: Symptoms, Diagnosis, and Imaging

A rare neurological condition called transverse myelitis is characterized by inflammation of the spinal cord. To diagnose and comprehend this illness, radiology is essential. Transverse Myelitis Radiology will be covered in detail in this article, including its appearance on an MRI, differential diagnosis, and more.

Longitudinal Extensive Transverse Myelitis Radiology

A spinal cord condition known as longitudinally extensive transverse myelitis describes inflammation that extends across several vertebral segments. Several radiological methods, including magnetic resonance imaging (MRI), can be used to observe this. The severe spinal cord involvement that frequently characterizes this form of transverse myelitis causes sensory and motor impairments. A vast area of the spinal cord is inflamed, which is the defining characteristic of longitudinally extensive transverse myelitis as shown by MRI images.

Acute Transverse Myelitis Radiology

Inflammation of the spinal cord appears suddenly in acute transverse myelitis. The diagnosis of this illness depends heavily on radiology, particularly MRI. On T2-weighted MRI scans, acute transverse myelitis frequently manifests as hyperintense lesions. These changes in the spinal cord’s myelin suggest areas of inflammation and demyelination.

Features of Transverse Myelitis on MRI

The spinal cord can be seen on an MRI, which is a useful technique for identifying anomalies linked to transverse myelitis. Hyperintense lesions on T2-weighted images are among the MRI’s distinctive features. The inflammation and demyelination that take place in the spinal cord’s afflicted regions are reflected in these lesions. Areas of active inflammation can also be found using gadolinium-enhanced MRI scans.

Hallmark of Transverse Myelitis

Inflammation of the spinal cord, particularly in the cord’s cross-sectional region, is the defining feature of transverse myelitis. In addition to pain, weakness, and a loss of bladder and bowel control, this causes sensory and motor deficits. This distinguishing characteristic must be confirmed using radiological imaging, particularly MRI.

Imaging of Acute Transverse Myelitis

Various imaging modalities are used to diagnose acute transverse myelitis, with MRI being the most useful. On T2-weighted imaging, acute lesions often show as hyperintense, but on T1-weighted images, they show as hypointense[6]. Accurate diagnosis is aided by the location of these lesions along the spinal cord as well as clinical signs.

Difference Between NMO and Transverse Myelitis

Transverse myelitis (TM) and neuromyelitis optica (NMO) are different diseases with some similarities. While transverse myelitis especially involves inflammation of the spinal cord, NMO mostly affects the optic nerves and spinal cord. Radiologically, NMO can be distinguished from transverse myelitis by the presence of longitudinally extensive lesions that span three or more spinal segments[7]. For effective treatment planning, this difference is essential.

Differential Diagnosis for Transverse Myelitis

Differential diagnosis is crucial since transverse myelitis-like symptoms can occur in a number of different medical diseases. Multiple sclerosis, acute disseminated encephalomyelitis (ADEM), and spinal cord compression from tumors or ruptured discs should all be taken into account. Transverse myelitis can be distinguished from various other disorders using radiology, particularly MRI.

Diagnosing Transverse Myelitis

Clinical assessment, radiographic imaging, and lab tests are used to diagnose transverse myelitis. In order to determine the severity of the lesions and confirm the existence of spinal cord inflammation, MRI scans are crucial. The diagnosis can also be supported by cerebrospinal fluid (CSF) tests, which can show greater protein levels and more white blood cells.

Common Site of Transverse Myelitis

There are several spinal cord segments that can be impacted by transverse myelitis. However, the most frequent site of involvement is the thoracic region. Radiological imaging aids in diagnosis and therapy planning by determining the precise location and degree of inflammation.

CSF Findings for Transverse Myelitis

Analyzing the cerebral spinal fluid is an important part of transverse myelitis diagnosis. Increased white blood cells and higher protein levels in the CSF can result from spinal cord inflammation[12]. These findings help to provide a thorough diagnosis when they are paired with clinical and radiographic data.


Transverse myelitis must be diagnosed and understood using radiology, and MRI in particular. The distinguishing characteristics shown on imaging, such as spinal cord inflammation and hyperintense lesions on T2-weighted images, aid clinicians in correctly diagnosing and separating transverse myelitis from other illnesses. Clinical examination, radiographic imaging, and laboratory tests can all be integrated to help healthcare providers manage patients with this difficult neurological illness quickly and efficiently.
