Sparganosis is a rare parasitic infection caused by the plerocercoid larvae of Spirometra spp. That is seldom encountered in humans. Clinical presentations are often nonspecific, and imaging findings can mimic other soft tissue lesions and lead to misdiagnosis. We present a case of a 14-year-old female with an abdominal wall lesion initially suspected to be cutaneous endometriosis, which was later diagnosed as sparganosis. Case Presentation: A 14-year-old female presented with a progressively enlarging, tender subcutaneous mass located superior and left of the umbilicus. The lesion was associated with intermittent pain, particularly exacerbated during menstruation, which raised clinical suspicion for cutaneous endometriosis. Abdominal MRI revealed a 2.5 cm subcutaneous mass with heterogeneous signal intensity on both T1- and T2-weighted images. Areas of hyperintensity suggested hemorrhagic components, which can be seen with endometriotic implants. The patient underwent surgical excision of the mass. Intraoperatively, a well-defined subcutaneous lesion was removed without complications. Histopathological examination unexpectedly revealed a cestode consistent with Spirometra spp. (sparganosis), along with mixed inflammation, granulation tissue formation, and focal necrosis. The cystic structure corresponded to the parasite's infection site. Postoperative management included prescribing albendazole therapy following stool sample collection to rule out residual parasitic infection. Discussion: Sparganosis is an uncommon parasitic infection in humans that is typically acquired through ingestion of contaminated water or undercooked meat from intermediate hosts. It often presents as a slowly growing subcutaneous mass, which can be mistaken for other soft tissue lesions such as lipomas, cysts, or, as in this case, endometriosis. Imaging findings are nonspecific; MRI may show cystic or solid masses with variable enhancement patterns. In this patient, MRI findings closely resembled cutaneous endometriosis due to the presence of hemorrhagic components within the lesion. Definitive diagnosis of sparganosis is usually established postoperatively via histopathological identification of the parasite. This case demonstrates the importance of considering parasitic infections in the differential diagnosis of subcutaneous masses. Read More

Fluoroscopic voiding cystourethrograms (VCUG) play a crucial role in pediatric radiology, enabling real-time visualization of the lower genitourinary tract. This educational exhibit summarizes the clinical indications, technique, clinically significant findings, and potential complications associated with VCUG, aiming to provide a strong foundational review for radiologists-in-training. The lower genitourinary tract, comprising the ureters, bladder and urethra, is implicated in various pediatric pathologies that can lead to long-term morbidity if left undiagnosed or untreated. VCUG is a dynamic study, allowing for visualization of the lower genitourinary tract bladder and urethra during filling and voiding, making it an invaluable tool in pediatric radiology for detection of both functional and structural pathologies. In this presentation we will review the most common indications for VCUG in the pediatric population as well as use a case-based approach to the discuss the following pathologies associated with the lower genitourinary tract and related conditions of surgical interest. ●Vesicoureteral reflux and its grading ●Congenital Abnormalities -Posterior Urethral Valves -Diverticula -Anorectal malformations -Prune belly syndrome -Duplicated renal collecting system -Congenital Megaureter ●Trauma -Urethral disruption -Urethral stricture -Bladder injury/disruption ●Post-operative evaluation -Ureteral reimplantation We will also discuss tips and tricks for the performance of the pediatric VCUG. Additionally, in the face of complications, prompt recognition and intervention remain crucial. We will review commonly encountered challenges faced by the performing radiologist. Fluoroscopic VCUG remains an invaluable diagnostic tool in pediatric radiology. For radiologists-in-training, mastering the technique, understanding clinical indications, and being able to interpret findings accurately are essential. With patient-centered care and adherence to best practices, VCUG can provide vital insights into pediatric lower urinary tract pathologies. Read More
