Congenital prepubic sinus is a rare congenital anomaly of the urinary tract and is clinically active by discharge from a skin opening overlying the symphysis pubis. Its etiology is still unclear, and a variant of dorsal duplication of the urethra is the favored theory. It has been reported in males as well as in females. Its size and extent are variable, starting from prepubic area extending toward the bladder or urethra and may have a blind end.. This report is about the imaging approach in a series of 5 cases with similar clinical signs of presentation.

The purpose of this exhibit is to provide radiologists at various levels of training with a concise and comprehensive illustrated review of anomalies associated with persistence of the falcine sinus. The exhibit will rely on literature review, illustrations, and multimodality imaging from patients with persistent falcine sinus associations. Read More

Genitourinary abnormalities are frequently detected on prenatal imaging. Though many anomalies are easily diagnosed on ultrasound and MR imaging, those that lead to hydrocolpos are not always as easy to distinguish. The purpose of this educational poster is to review the causes of prenatal hydrocolpos and provide an organized approach to differentiate these entities on prenatal imaging.

Several examples of ultrasound and fetal MR imaging are provided to illustrate multiple abnormalities that can produce hydrocolpos (e.g., cloacal malformations, persistent urogenital sinus, congenital adrenal hyperplasia, transverse vaginal septum, imperforate hymen, vaginal atresia) and to distinguish other lesions that may mimic hydrocolpos (e.g., sacrococcygeal teratoma, ovarian cyst).

A diagnostic approach is provided for differentiating the various causes of hydrocolpos on prenatal imaging. When available, postnatal imaging, physical examination, and endoscopic correlations are provided for diagnostic confirmation or clarification. Complications and associated abnormalities are discussed to provide additional considerations for prenatal evaluation and treatment planning. At the end of this module, viewers will better understand and differentiate the various entities that lead to hydrocolpos on prenatal imaging. Read More

The diagnostic approach to fever of unknown origin (FUO) in a neutropenic child is challenging. Recommendations of the Children's Oncology Group and the ACR provide some guidance, but evidence basis for use of sinus CT in the acutely febrile neutropenic child is poorly established. This presentation assesses baseline paranasal sinus mucosal thickening in children in 2 separate cities and compares them to children with neutropenia undergoing sinus CT in the work-up of FUO.

An 8-week-old male, born without complication at 33 weeks gestation age, presented with an undifferentiated posterior-midline scalp mass that had been present since birth. According to the mother, the mass has progressively increased in size with subjective tenderness to palpation. The mother reported possibly relevant two seizure-like episodes around 5 weeks of age consisting of jerking leg movements and staring spells with rapid blinking. Otherwise, the infant was healthy without any documented past medical or surgical history. Based on the presentation, a dedicated sonogram of the head was ordered with the goal of visualizing the mass and underlying cranial anatomy. The mass was demonstrated to be extracranial with avid vascularity. A few images raised suspicion for a trans-osseous vascular connection between the mass to the sub-adjacent dural venous sinuses. Subsequent contrast enhanced MRI and MRV imaging was ordered to distinguish the leading differential of Sinus Pericranii and Atretic Parietal Cephalocele. On MRI, the highly vascular extracranial mass demonstrated enhancement pattern similar to the dural venous sinuses. A trans-ossoeus vascular channel was seen arising from the mass coursing intracranially and communicating with the superior sagittal sinus. No arterial channel was visualized. No evidence of a persistent falcine venous sinus, primitive falcine vein or CSF tract was visualized. Subsequently, the diagnosis of Sinus Pericranii was established.

Sinus Pericranii and Atretic Parietal Cephalocele are extracranial subscapular masses that present similarly on physical examination and overall presentation. Sinus Pericranii is a low flow vascular malformation with an abnormal connection to the dural sinuses. Atretic parietal cephaloceles are small subscapular lesions with dura, dysplastic brain and fibrous tissue associated with variant intracranial anatomy including a persistent falcine venous sinus/primitive vein and/or abnormal CSF tract. Subsequently imaging findings are essential in distinguishing between the two entities and arriving at a definitive diagnosis. The presented case demonstrates this scenario. Read More

The human airway is fundamental to respiratory gas transmission and oxygen exchange. The pediatric upper airway is subject to a number of specific age and location related disease processes that can cause alarming morbidity and could be deadly by impairing normal air movement. In this exhibit, we guide the learner on a fantastic journey thorough the pediatric upper airway from nose to cords illustrated thorough neuroimages. Congenital and acquired anatomic and pathologic barriers to airflow will be reviewed. Read More
