Multidetector computed tomography in the evaluation of hereditary multiple exostoses

Area of Science:

• Radiology
• Medical Imaging
• Orthopedics

Background:

• Hereditary multiple exostoses (HME) is an autosomal dominant disorder.
• Osteochondromas are characteristic of HME.
• Magnetic resonance imaging (MRI) is the preferred modality for HME due to soft tissue contrast and lack of radiation.

Purpose of the Study:

• To review the utility of multidetector computed tomography (MDCT) in evaluating patients with HME.
• To discuss the role of MDCT in assessing HME-related complications.

Main Methods:

• Review of low-dose MDCT techniques.
• Discussion of 3D visualization methods.
• Analysis of typical MDCT appearances and differential diagnoses.

Main Results:

• MDCT is valuable for evaluating HME and its complications.
• Specific applications include assessing spinal cord compression, pneumothorax, pseudoaneurysms, fractures, and growth disturbances.
• MDCT aids in identifying chondrosarcoma transformation and soft tissue involvement.

Conclusions:

• MDCT offers significant value in the comprehensive evaluation of Hereditary multiple exostoses.
• It is particularly useful for assessing bony structures and emergent complications where MRI may be limited.
