AI Article Synopsis
- A 58-year-old woman had a tumor found in her left kidney area during a CT scan.
- MRI showed the tumor's unique characteristics, prompting doctors to suspect it might be cancerous.
- After surgery to remove the tumor, it was confirmed to be a benign Schwannoma, highlighting the challenge of distinguishing between benign and malignant tumors in that region.
Article Abstract
A 58-year-old female presented with a well-encapsulated tumor in the left renal hilum on computed tomography (CT). On magnetic resonance imaging (MRI), the tumor showed low intensity on the T1-weighted image, high intensity on the T2-weighted image. Laparoscopic radical nephrectomy was performed because we could not exclude the possibility of malignancy such as renal cell carcinoma. Histopathological examination revealed that the tumor was a benign Schwannoma. Although renal hilum is a common site of renal schwannoma, it is difficult to differentiate benign tumors from malignant ones, and then nephrectomy is usually performed.

Background: Ectopic cortisol-producing adrenocortical adenoma (ECPA) is extremely rare, with only a few cases reported. Retroperitoneal schwannoma is also uncommon, accounting for only 0.7-5% of all schwannomas.

Key Clinical Message: Benign ancient retroperitoneal schwannomas (BARS) exhibit abdominal masses and flank pain to incidental findings at more advanced stages. Histopathological and immunohistochemical analysis is essential for confirmation of benign nature. Our patient was misdiagnosed as ureteric colic, highlighting the need to consider BARS in differential diagnosis to prevent complications like hydronephrosis.

Schwannomas are usually benign tumors typically found in the head, neck, and extremities, with approximately 3% originating in the retroperitoneum. In this case, a young male presented with incidental masses in the left kidney and retroperitoneum. Abdominal pelvic enhanced computerized tomography (CT) revealed a tumor apparently originating from the left kidney, along with a retroperitoneal mass suspected to be a metastatic lymph node.

Schwannomas are tumors that commonly affect the nerve sheath, typically involving peripheral and cranial nerves. These tumors are rarely found within the pelvis and retroperitoneum. To date, there have been no documented cases of concurrent chromophobe renal cell carcinoma and pelvic schwannoma.

Background: Schwannomas in the renal hilum are rare among retroperitoneal tumors. However, the possibility of malignant findings cannot be ruled out, and surgery is often indicated. This case was expected to be difficult to remove laparoscopically because the tumor was sandwiched between the arteriovenous veins of the renal portal.
