Ganglioneuroblastoma is a variant of neuroblastoma tumours with mature ganglion cell differentiation which occurs commonly in cervical, mediastinal and retroperitoneal locations. Approximately 90% of ganglioneuroblastomas are seen in children younger than five years old. There are 50 adult cases of ganglioneuroblastomas reported to date. Our patient is the 51st case and she is the first to be diagnosed in pregnancy. Our patient's tumour site was the thoraco-abdominal retroperitoneal space adjacent to her kidney. This tumour is generally diagnosed incidentally or by compression presentations, i.e. pain or neurological symptoms. Our patient's ultrasound scan appearances triggered suspicion of an atypical mass after presenting with loin pain. Caesarean section with tumour removal in the same session is preferred if tumour is small and localized. However in this case, there was uncertainty regarding the extent of the tumour. Therefore, the patient underwent thoracotomy after delivery to excise the thoraco-abdominal tumour, which extended from the level of the T9 to L2 vertebrae.

Chronic abdominal pain is a very common complaint in the population of children and adolescents. In most cases, the usual cause are functional gastrointestinal disorders. However, in a few percent of children, the reason for persistent chronic stomach pain are organic diseases occurring in the gastrointestinal tract, as well as parenteral diseases, including uro-genital tract abnormalities, inflammation of the lower respiratory tract and cancer processes. Among organic causes, in addition to those commonly encountered, such as: intolerances and food allergies, gastroesophageal reflux disease, chronic gastritis or duodenitis, or urinary tract infections, the diagnosis should also include very rare causes, for example, neoplastic diseases, among them tumors of the abdominal cavity. In the case described in the present article, a 6-year-old girl with chronic abdominal pain, symptoms of gastro-oesophageal reflux and constipation, and previously diagnosed food allergy and lactose intolerance, was referred for widening the diagnosics due to the occurrence of alarm symptoms. The nodule revealed in the chest X-ray, in CT scan, turned out to be a paravertebral tumor with the specific features of neuroblastoma. After a macroscopically complete tumor resection based on the result of histopathological examination, the diagnosis of ganglineuroblastoma was established. The presence of alarm symptoms in anamnesis and physical examination in children with abdominal pain suggests a higher probability of the organic origin of the disease and should always lead to extended diagnostics. Ganglioneuroblastoma is a very rare disease, in most cases is located primarily in the abdominal cavity, and the most common associated symptom is abdominal pain.

Ganglioneuroblastoma, neuroblastoma, and ganglioneuroma (GN) are the tumors that arise from the neural crest cells. Of these, GN has the most benign origin without metastatic potential. The most common sites of their origin are the posterior mediastinum and retroperitoneum. Although the imaging studies, including CT, are available to detect these tumors, the definitive diagnosis can only be made by histological examination. We present a case of a 40-year-old woman with a retroperitoneal GN causing longstanding, gradually increasing, uncontrolled abdominal pain due to its pressure effect on the pancreas, duodenum, and right kidney with the displacement of the inferior vena cava. An exploratory laparotomy was performed, and the mass was removed. Histopathology confirmed the benign nature of the mass (a GN). These tumors are rarely malignant and mostly asymptomatic. However, in our case, abdominal pain was affecting the patient's life. After a discussion with the patient, an elective surgical procedure was performed, and the patient was symptom-free postoperatively and able to resume her regular routine.
