“…The left sciatic nerve was thickened and T2 hyperintense at the greater sciatic foramen, presumed to be related to compression. Intraspinal extension is rare but has been previously reported for sacrococcygeal teratoma (SCT) 12 . On a subsequent nuclear medicine bone scan there was normal bone marrow signal and no osteoblastic metastatic disease.…”

“…3 Transperineal ultrasound with a high-frequency linear transducer can be considered an efficient, safe, non-invasive adjunct investigative tool for infants with bladder outlet obstruction, palpable pelvic floor mass or perianal mass. Many imaging departments have a high-frequency linear transducer available (12)(13)(14)(15) which can provide superior resolution to transabdominal or endocavity transducers which may be more appropriate for the adult population.…”

The value of transperineal ultrasound to women's imaging of pelvic floor prolapse or perineal trauma is extensively documented. 1,2 The midsagittal two-dimensional transperineal ultrasound scan plane while simple to obtain, is difficult to interpret without prior knowledge of pelvic floor sonoanatomy. While transabdominal pelvic ultrasound is routinely taught within tertiary ultrasound courses, hands-on experience performing transperineal ultrasound remains dependent on the patient demographic within the imaging department, clinically relevant requests, adequate supervision, and patient consent. These factors can limit exposure and opportunity to gain proficiency and confidence with pelvic floor ultrasound. Even if the operator has adequate skill and experience in adult pelvic floor ultrasounds, a paediatric patient may be poorly compliant and technically challenging. Nevertheless, the transperineal ultrasound can offer many advantages when performed in the paediatric population.Literature on pelvic floor ultrasound in the paediatric population is relatively scarce. High-resolution midsagittal ultrasound over the perineum with a linear or curvilinear transducer can demonstrate the pubic symphysis, lower bladder and urethra, vagina, lower rectum and anal sphincters in a singular imaging plane. 1 Normal anatomy is outlined in Figure 1.

Presacral space is a potential space between the rectum anteriorly and lumbosacral spine posteriorly containing derivatives from various primitive germ cell types which serve as origin to a myriad of tumors. Imaging plays a vital role in diagnosis, characterization, assessing extent and evaluation of spread. We present a series of six cases of pediatric presacral tumors with intraspinal extension. The series comprises of an immature sacrococcygeal teratoma (Altman type II), a malignant sacrococcygeal teratoma (Altman type IV), a neuroblastoma, a rhabdomyosarcoma, a clear cell sarcoma and an Ewing’s sarcoma of the ilium which can be broadly categorized as tumors of germ cell, neuroblastic, mesenchymal, osteogenic origin. In spite of overlapping imaging features, careful retrospective observation revealed few distinctive features that would aid in optimal characterization of tumors with a fair degree of certainty.In summary, the salient imaging features that aid in differentiation are the epicentre of the tumor, pattern and degree of bone involvement, status of sacral foramina and neural elements and internal characteristics such as presence of fat, calcification, hemorrhage, necrosis, etc.

“…Presacral tumors in children with the potential for intraspinal extension, based on the existing literature, are enumerated in Table 2. 4,[6][7][8][9] Intraspinal extension of presacral tumors can impact risk stratification, the choice of treatment modality, the probability of surgical complications and the prognosis. Imaging plays an imperative role in the diagnosis, characterization, assessment of extension, evaluation of spread, planning management and preoperative planning.…”

The presacral space is a potential space located between the rectum and the lumbosacral spine. It contains various primitive germ cell types that serve as the origin for a range of tumors. Imaging is crucial in characterizing, assessing the extent of and evaluating the treatment response to these tumors. We report a series of six cases of pediatric presacral tumors with intraspinal extension, including an immature sacrococcygeal teratoma (Altman type II), a malignant sacrococcygeal teratoma (Altman type IV), a neuroblastoma, a rhabdomyosarcoma, a clear cell sarcoma and an Ewing's sarcoma of the ilium. These tumors can be broadly categorized as tumors of germ cell, neuroblastic, mesenchymal and osteogenic origin. Despite overlapping imaging features, a review of the existing literature and careful retrospective observation revealed several distinctive features that aid in the optimal characterization of tumors. These include the tumor's epicenter, the pattern and degree of bone involvement, the status of sacral foramina and neural elements, and internal tumor characteristics such as the presence of fat, calcification, hemorrhage and necrosis.
