Abstract:
Magnetic resonance imaging was performed as a preoperative examination in three children with neurofibromatosis and soft-tissue plexiform neurofibromas. In all three patients, MRI showed more widespread soft tissue involvement than was suspected clinically including extension towards the spine in each case. Patient management was changed in each case after MRI was performed.
Insights
Magnetic resonance imaging (MRI) revealed extensive soft-tissue involvement in children with neurofibromatosis, impacting patient management. This advanced imaging technique identified previously unsuspected spinal extension of plexiform neurofibromas.
Area of Science:
- Medical Imaging
- Oncology
- Pediatrics
Background:
- Neurofibromatosis is a genetic disorder characterized by tumor development.
- Plexiform neurofibromas are benign tumors that can grow extensively in soft tissues.
- Preoperative assessment is crucial for managing these complex tumors.
Observation:
- Three pediatric patients with neurofibromatosis and soft-tissue plexiform neurofibromas underwent preoperative Magnetic Resonance Imaging (MRI).
- Clinical examination underestimated the full extent of soft tissue involvement in all cases.
- MRI demonstrated more widespread disease than initially suspected.
Findings:
- MRI revealed significant soft tissue infiltration beyond clinical detection in all three children.
- A key finding was the extension of neurofibromas towards the spine in every patient.
- The imaging findings provided a more comprehensive understanding of tumor burden.
Implications:
- MRI findings directly altered patient management strategies in all cases.
- The study highlights MRI's critical role in accurately staging neurofibromatosis.
- Enhanced preoperative imaging improves surgical planning and patient outcomes for pediatric neurofibromatosis.
