Summary
Computed tomography (CT) can differentiate benign from malignant neurogenic tumors in the abdomen and pelvis, potentially avoiding invasive biopsies. This imaging technique aids in assessing tumor characteristics, resectability, and treatment response.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Abdominal and pelvic neurogenic tumors are rare in adults, except in neurofibromatosis patients.
- Malignant transformation occurs in 2.4-29% of neurofibromatosis cases.
- Biopsies of neurofibromas risk sensorimotor nerve damage.
Purpose of the Study:
- To evaluate the utility of computed tomography (CT) in distinguishing benign from malignant neurogenic neoplasms.
- To assess CT's role in surgical planning and treatment monitoring.
Main Methods:
- Review of CT scan characteristics of neurogenic tumors.
- Analysis of imaging features differentiating benign from malignant neoplasms.
- Correlation of imaging findings with clinical outcomes.
Main Results:
- Benign tumors appear well-demarcated, solid, homogeneous, hypodense, and enhance with contrast.
- Malignant tumors are often large, irregular, infiltrative, necrotic, and show heterogeneous enhancement.
- CT effectively distinguishes malignancy, predicts resectability, detects metastases, and monitors treatment.
Conclusions:
- Computed tomography is a valuable tool for diagnosing abdominal and pelvic neurogenic tumors.
- Imaging can guide management by differentiating benign from malignant lesions, potentially avoiding biopsy.
- CT aids in treatment planning and response evaluation for neurogenic neoplasms.
