Retroperitoneal ganglioneuroma is a rare benign tumor that is challenging in terms of clinical diagnosis.Computed tomography and magnetic resonance imaging are usually performed for diagnosis rather than convenient and inexpensive ultrasonography.Here,we present the case of a 21‐year‐old female patient who was diagnosed by multimodal ultrasound imaging and whose diagnosis was confirmed by ultrasound‐guided core needle biopsy before surgery.We hope that this rare case will help clinicians and radiologists realize the advantages of multimodal ultrasound imaging in the diagnosis of retropeitoneal solid tumors,and reduce misdiagnosis.

BACKGROUND ganglioneuroma (GN) is a rare neurogenic tumor that accounts for about 0.1%- 0.5% of all tumors of the nervous system.It originates from neural crest cells.GN has no specific clinical symptoms or laboratory findings,which leaves it easily overlooked and misdiagnosed as other tumors.Retroperitoneal GN with very large volume and vascular penetration is extremely rare.CASE SUMMARY We present the imaging and pathological findings of a giant retroperitoneal GN in a child.A 4-year-old boy had suffered from postprandial vomiting for more than 6 mo with no precipitating factors.Abdominal computerized tomographic examination showed a giant cystic mass in the retroperitoneal area.After injection of contrast agent,the mass showed heterogeneous enhancement.Surgery with local excision of the mass was performed to address the embedded abdominal blood vessels,and the histopathological and immunohistochemical diagnosis of the mass was GN.Postprandial vomiting was relieved,and no complications occurred after the operation.CONCLUSION In the diagnosis of giant retroperitoneal hypodense masses in children,GN should be considered if the mass presents delayed enhancement,punctate calcification,and vascular embedding but no invasion.Pathology is the golden standard for the diagnosis of GN,and surgical excision is the optimal treatment for GN.

BACKGROUND ganglioneuromas are mature, benign neurogenic tumors that arise from neural crest-derived cells. Given the rarity of these tumors and their often close proximity to major vessels, there is a paucity of reports in the literature of minimally invasive resections of ganglioneuromas near the celiac plexus. We report a case of laparoscopic resection of a retroperitoneal ganglioneuroma adhering to the portal vein and celiac axis.CASE SUMMARY A 27-year-old female was referred to our medical center with a symptomatic retroperitoneal mass. Using high quality preoperative imaging and biopsies, we confirmed the diagnosis of a 4 cm ganglioneuroma abutting the celiac axis, portal vein, and the caudate lobe of the liver. We elected for laparoscopic resection after careful preoperative planning and discussions with the patient. Laparoscopy enhanced visualization of the tumor and its relationships to surrounding vital structures for optimal dissection. Ultrasonic energy devices and adjusting liver retraction to allow for manipulation of the mass facilitated a safe and effective resection in a tight space. There were no operative complications and the patient was discharged home on postoperative day 1 with no residual symptoms upon follow-up. With sufficient experience in laparoscopic surgery and preoperative imaging and diagnostics, a minimally invasive approach for removing this celiac plexus ganglioneuroma was successful.CONCLUSION In carefully selected patients, laparoscopic ganglioneuroma resection is appropriate, reducing postoperative morbidity, hospital length of stay, and recovery time.

Adrenal ganglioneuromas(GNs) constitute rare,differentiated tumors which originate from neural crest cells. GNs are usually hormonally silent and tend to be discovered incidentally on imaging tests. Adrenalectomy is the gold standard for the treatment of primary adrenal GNs. Nevertheless,preoperative differential diagnosis of GNs remains extremely challenging,and thus histopathological examination is required in order to confirm the diagnosis of GN. Overall,prognosis after surgical resection seems to be excellent,without any recurrences or need for adjuvant therapy.

Objective:to investigate the clinical and pathological characteristics of bronchial cyst of the posterior mediastinum misdiagnosed as a ganglioneuroma,and to improve the level of their diagnosis,diflerential diagnosis,and treatment.Methods:the clinical data and pathological findings of a young woman misdiagnosed with a ganglioneuroma was collected and analyzed,and the relevant literature were reviewed.Results:the patient had no specific clinical symptoms.The right posterior mediastinum was accidentally found due to a physical examination for COVID-19.The enhanced chest computed tomography(CT)showed a ganglioneuroma.After a thoracoscopic resection of the lesion,a pathological diagnosis revealed a posterior mediastinal bronchial cyst.Conclusion:bronchial cyst of the mediastinum is rare and their clinical symptoms are atypical and can be easily diagnosed as a ganglioneuroma.It can be preliminarily judged by laboratory and imaging examination and con-finned by pathological examination.The main treatment is surgical resection.

ganglioneuroma is a rare benign tumor, which is usually located in the posterior mediastinum and retroperitoneum. Occasionally, it involves the paraspinal region with intraspinal extension and becomes dumbbell shaped. Dumbbell ganglioneuromas rarely affect the lumbar spine, and only nine cases of dumbbell lumbar ganglioneuromas have been reported previously. We are reporting an extremely rare case of a giant dumbbell tumor in the lumbar spine. We performed a one stage total resection of the tumor with posterior approach and long-segment fixation and fusion. This approach is different from previous methods. Histopathological examination of the surgical specimen confirmed the diagnosis of ganglioneuroma. Thirty months follow up showed a satisfactory outcome. Single-stage posterior tumor resection with fixation and fusion is effective and an appropriate choice for the treatments of lumbar dumbbell ganglioneuromas.

BACKGROUND ganglioneuromas are rare tumors of the sympathetic nervous system that originate from neural crest sympathogonia.Since the cervical spine has rarely been reported as a site for ganglioneuroma,we present a case report on this uncommon manifestation.CASE SUMMARY A 34-year-old male presented with a 4-month history of progressive paralysis of both upper limbs along with an unsteady gait.The touch sensitivity of both hands was reduced,and there was conspicuously high muscle tonus in his upper and lower limbs,along with hyperactive physiological reflection and deep reflexes.Magnetic resonance imaging showed several nodules around the C2-7 intervertebral foramena,among which the masses lying between C1 and C2 were obviously bilaterally compressing the spinal cord.Successful posterior decompression was performed without fixation and the tumors in the upper cervical spine were removed intact,with rapid relief of symptoms.The pathological diagnosis was ganglioneuroma.CONCLUSION Multiple and bilateral ganglioneuroams are a rare occurrence in the cervical spine.In this case report,timely resection of the neoplasms around C1 and C2 resulted in spinal cord decompression,with rapid relief of symptoms and a good prognosis.Including the current case,we are aware of only seven such cases in the literature,of which four arose from Japan,one from China,and one from Sp-ain.We suppose that ethnicity and geographic associations with this rare disease presentation may be an aspect for future consideration and investigation.

ganglioneuromas (GN) are rare, benign neurogenic tumors that arise from sympathetic ganglia. They are often asymptomatic. However, in rare cases, they may secrete catecholamines, vasoactive intestinal polypeptides (VIP), or androgenic hormones and manifest with flushing, symptoms of catecholamine excess or chronic diarrhea. We report a young Saudi girl with chronic secretory diarrhea, severe hypokalemia and abdominal distension. After an extensive work up, a well-defined hypodense heterogeneous mediastinal mass was noted in radio imaging. A complete recovery was seen after surgical removal of that mediastinal mass which turned to be a ganglioneuroma.
