Ganglioneuromas are benign tumours of the sympathetic nervous system that originate from neural crest cells. They are extremely rare in the presacral region. Here, we report a case of a presacral mass in a 14-year-old female who presented with complaints of pelvic discomfort, difficulty with micturition and constipation. Ultrasonogram showed a large heteroechoic solid mass in the pelvis with bilateral hydroureteronephrosis. It appeared as a well-circumscribed, hypodense mass lesion on CT scan, measuring 14 x 11 x 10 cm. It appeared isointense to muscle on and heterogeneously hyperintense on weighted images with heterogeneous post-contrast enhancement on MRI. The lesion was seen in the presacral region displacing the rectum and bladder anteriorly, and extending posteriorly, causing widening of the sacral foramina. The mass was surgically excised and her symptoms resolved. Histopathological examination of the mass revealed features of ganglioneuroma. We report this case in view of the large size of the mass and its rare location.

Mature cystic teratoma mimicking a tailgut cyst in an adolescent female: a case report.

Article Synopsis
- Presacral tumors are rare, especially in children, and can come from different cell types that develop during embryonic growth.
- A case study of a 13-year-old girl showed initial imaging suggested a tailgut cyst, but surgery revealed it was actually a mature cystic teratoma, which is unusual for her age.
- The surgery required careful dissection due to adhesions, and the diagnosis highlights the importance of surgical exploration over just imaging to accurately identify and treat presacral masses.
Castleman's Disease Presenting as an Unusual Pelvic Retroperitoneal Mass.

Castleman's disease (CD) is characterised by benign lymphoepithelial proliferation and is a peculiar form of angiofollicular lymph node hyperplasia rather than a neoplasm or a hamartoma. CD is broadly classified as unicentric CD (UCD) and multicentric CD. In the unicentric variant, patients have localised disease affecting only a single lymph node or a group of adjacent nodes in a single region, which clinically presents as an enlarging mass without any other significant symptoms.

Background: The authors report on a patient who presented with an extremely large presacral schwannoma and subsequent mass effect-induced hydronephrosis and kidney failure. To the authors' knowledge, this case represents the largest radiographically verified spinal schwannoma in the medical literature. The tumor presented here was more than three times as large as a typical giant schwannoma.

Diphallia, also known as penile duplication, represents a highly unusual congenital abnormality of sex development, occurring in 1 in every 5 million to 1 in thirty million live births. Wecker, in Bologna, Italy, noted the first instance of diphallia in 1609. Meanwhile, no sufficient report has meticulously described the incidence in Indonesia.

Introduction: Anal canal duplication (ACD) is a rare entity of gastrointestinal duplication that may be asymptomatic or present complications, such as abscess, fistulae, or malignant changes. The diagnosis and rational management of ACD still need to be clarified.
Case Presentation: We present a case of an 18-month-old girl with intractable perianal erosion and painful bowel movements for one year, and chronic constipation for six months.
