A young woman has regained full mobility following successful laparoscopic removal of a rare benign nerve tumour from her pelvis at Semmelweis University in Budapest. The 2026 case demonstrates the clinical value of intraoperative neuromonitoring—a specialist technique that allows surgeons to map and preserve neural structures during tumour removal, minimising the risk of neurological damage.
Key takeaways
- A benign schwannoma (nerve sheath tumour) in the lesser pelvis was successfully removed using minimally invasive laparoscopic surgery with real-time nerve monitoring
- The procedure required coordinated collaboration between the Department of Obstetrics and Gynecology and the Department of Neurosurgery and Neurointervention, supported by a newly acquired mobile neuromonitoring device
- The patient was discharged fully recovered within 24 hours, with preserved neurological function and restored ability to walk

What is a pelvic schwannoma?
A schwannoma (also called a neurinoma) is a benign, slow-growing tumour that arises from the myelin sheath surrounding peripheral nerves. When located in the lesser pelvis—the anatomical space between the pelvic bones containing reproductive and urinary organs—such tumours are rare and pose a surgical challenge: removal must balance complete tumour excision against preservation of nearby neural and vascular structures to maintain continence, sexual function, and mobility.
The patient in this case presented with progressive neurological symptoms affecting her gait and quality of life. Preoperative imaging (likely MRI) would have identified the lesion’s location, size, and relationship to nearby nerves, informing the surgical approach. The decision to pursue laparoscopic rather than open surgery reflects advances in minimally invasive technique and intraoperative imaging guidance.
The critical role of intraoperative neuromonitoring
Intraoperative electrophysiological monitoring—also known as neuromonitoring—involves real-time measurement of nerve electrical activity during surgery. Surgeons use this live feedback to identify and map functional nerve pathways, allowing them to preserve tissue critical to motor control, sensation, and autonomic function (continence and sexual response). This technology is particularly valuable in pelvic tumour surgery, where densely packed nerves govern essential functions.
According to Semmelweis University‘s Department of Obstetrics and Gynecology, the recently acquired specialized mobile neuromonitoring device enabled the surgical team to perform what they describe as the region’s distinctive neuropelveology programme. This interdepartmental collaboration between obstetrics–gynaecology and neurosurgery exemplifies the model needed for safe management of complex pelvic nerve pathology.
The patient was discharged fully recovered within 24 hours of laparoscopic schwannoma removal, with preserved neurological function and restored mobility, supported by intraoperative electrophysiological monitoring.

Interdepartmental coordination as a quality standard
This case underscores why rare tumour surgery demands multidisciplinary teamwork. The obstetrics and gynaecology team brought anatomical expertise in pelvic anatomy and minimally invasive surgical technique; the neurosurgery and neurointervention team contributed neurological knowledge and neuromonitoring protocol. Neither alone could safely manage this lesion. In many healthcare systems across Central and Eastern Europe, such integrated programs remain sparse, meaning patients with pelvic nerve tumours may lack access to specialists equipped with both the surgical and monitoring capability for safe removal.
The addition of a dedicated mobile neuromonitoring device reflects Semmelweis University’s institutional investment in specialised infrastructure—a resource that enables safer outcomes and expands the scope of what can be treated laparoscopically rather than through larger open incisions. For patients, this means shorter hospital stays, faster recovery, and reduced surgical trauma.
Related clinical updates on minimally invasive procedures and advances in surgical neuromonitoring continue to improve outcomes for rare tumour management.
Implications for patients and healthcare systems
Early detection and access to specialist centres can dramatically alter the trajectory of care for rare pelvic tumours. A patient with a schwannoma who is referred to a generalist surgeon may face either delayed diagnosis or suboptimal surgery that damages nearby nerves. Centralisation of rare-tumour expertise—as demonstrated by Semmelweis University’s neuropelveology programme—ensures that patients receive best-evidence care with preservation of quality of life.
The 24-hour discharge and full neurological recovery in this case is not routine; it reflects meticulous surgical planning, real-time neuromonitoring, and the coordinated expertise of two specialist departments. This model merits attention from health policy makers planning rare-disease networks and from other teaching hospitals considering investment in integrated neuropelveology programmes.
What this means
Frequently asked questions
Is a schwannoma cancerous?
No. A schwannoma is a benign tumour of the myelin sheath surrounding nerves. It does not transform into cancer, though it can grow slowly and compress nearby structures. Surgical removal is indicated if the tumour causes progressive symptoms such as pain, numbness, or motor dysfunction—as in this patient’s case.
Why is intraoperative neuromonitoring important in pelvic tumour surgery?
Pelvic nerves govern continence, sexual function, and lower-limb motor control. Intraoperative neuromonitoring provides real-time feedback on nerve integrity, allowing surgeons to identify functional nerve pathways and preserve them during tumour removal. Without this technology, surgeons rely on anatomical landmarks alone, increasing the risk of permanent neurological injury.
What is the advantage of laparoscopic over open surgery for this procedure?
Laparoscopic surgery uses small incisions and magnified visualisation, reducing tissue trauma, blood loss, and post-operative pain compared with open approaches. When combined with intraoperative neuromonitoring, it allows safe tumour removal with faster recovery. This patient was discharged within 24 hours—a recovery trajectory rarely achievable with open pelvic surgery.
The success of this case at Semmelweis University reflects a broader shift in rare-disease management: centralised expertise, invested infrastructure, and multidisciplinary teamwork are increasingly recognised as the pathway to better patient outcomes. As more teaching hospitals develop similar neuropelveology programmes, patients across Central and Eastern Europe should benefit from improved access to specialist care for these uncommon but debilitating conditions.
