Cross-sectional Imaging Anatomy and Pathologic Conditions Affecting Thoracic Nerves

Area of Science:

• Radiology
• Neuroanatomy
• Thoracic Imaging

Background:

• Awareness of thoracic nerves is crucial for radiologists, though often not directly visualized.
• Understanding normal nerve function aids in identifying neurologic signs and symptoms, guiding disease detection.
• Knowledge of nerve locations improves accuracy in diagnosing thoracic masses.

Purpose of the Study:

• To review the anatomy, function, and clinical significance of major thoracic nerves for radiologists.
• To emphasize the role of thoracic nerves in oncologic and surgical management.
• To highlight radiologic signs associated with nerve dysfunction, injury, and malignant involvement.

Main Methods:

• Descriptive review of thoracic neuroanatomy and related clinical presentations.
• Discussion of primary and secondary malignant involvement, iatrogenic, and traumatic injuries.
• Integration of clinical signs, symptoms, and radiologic findings for each nerve.

Main Results:

• Detailed description of the phrenic, vagus, recurrent laryngeal, intercostal, sympathetic chain, and brachial plexus.
• Review of clinical manifestations of nerve dysfunction and associated radiologic abnormalities.
• Emphasis on the impact of nerve involvement on patient management.

Conclusions:

• Familiarity with thoracic neuroanatomy and pathology is essential for effective cross-sectional imaging interpretation.
• Understanding nerve involvement aids in differential diagnosis and surgical/oncologic planning.
• This knowledge enhances diagnostic accuracy and patient care in thoracic radiology.
