Summary
Spinal invasive mole is a rare cause of metastatic lesions, typically spreading to the lungs, liver, or brain. This case report details a young patient who recovered fully after surgery and chemotherapy for a spinal invasive mole causing paraparesis.
Area of Science:
- Gynecologic Oncology
- Neurosurgery
- Oncology
Background:
- Gestational trophoblastic neoplasia (GTN) encompasses a spectrum of placental-derived tumors, with invasive mole being the most common form.
- Metastatic spread of invasive mole most frequently involves the lungs, liver, and brain.
- Spinal involvement by invasive mole is exceptionally rare, posing diagnostic and therapeutic challenges.
Observation:
- A 24-year-old female presented with paraparesis, a neurological deficit indicating spinal cord compromise.
- Diagnostic imaging revealed an extradural spinal mass consistent with metastatic invasive mole.
- The patient's presentation with paraparesis secondary to spinal invasive mole represents a highly unusual metastatic pattern.
Findings:
- Surgical decompression and biopsy were performed to alleviate spinal cord pressure and obtain tissue diagnosis.
- Histopathological examination confirmed the presence of invasive mole tissue within the spinal extradural space.
- The patient received subsequent chemotherapy, demonstrating a positive response to treatment.
Implications:
- This case highlights the importance of considering rare metastatic sites in patients with a history of molar pregnancy.
- Early diagnosis and multimodal treatment, including surgery and chemotherapy, can lead to favorable outcomes even in rare presentations.
- Further research into the mechanisms of rare metastatic spread in GTN may improve risk stratification and treatment strategies.
