Pelvic MRI in children with Crohn disease and suspected perianal involvement.

MRI is an important imaging tool in evaluation of adult and pediatric patients with Crohn disease. Pelvic MRI, in particular, has become the method of choice to evaluate for perianal fistulas and associated complications of Crohn disease. MRI can define the extent and location of perianal fistulas and abscesses, as well as provide critical information for operative management. In this pictorial essay, we describe useful MRI techniques for evaluation of perianal complications in pediatric patients with Crohn disease. We review pertinent anatomy and illustrate typical examples of perianal fistulas with and without abscess. We show one case of clinically suspected perianal fistula that was actually a pilonidal sinus.

Tuberous sclerosis complex and renal angiomyolipoma: case report and review of the literature.

A 5-year-old boy with a known diagnosis of tuberous sclerosis complex was found to have an enlarging renal mass on routine ultrasound. He was diagnosed with an angiomyolipoma (AML) and scheduled for close observation. Follow-up magnetic resonance imaging demonstrated the AML to be significantly enlarged and hypervascular. Selective arterial embolization of the tumor was performed, which resulted in an appropriate decrease in tumor size. Angiomyolipoma is a known and well-described complication of the tuberous sclerosis complex that is usually found among patients in their adolescent and adult years. The case presented here illustrates the need for early and repeated renal imaging of younger pediatric patients with tuberous sclerosis. Our experience adds to the literature on young pediatric patients requiring embolization for treatment of large renal angiomyolipomas.

Low-dose CT colonography in children: initial experience, technical feasibility, and utility.

BACKGROUND: CT colonography (CTC) is utilized as a diagnostic tool in the detection of colon polyps and early colorectal cancer in adults. Large studies in the literature, although focused on adult populations, have shown CTC to be a safe, accurate, non-invasive technique. OBJECTIVE: We evaluated the technical feasibility of CTC in children using a low-dose technique. MATERIALS AND METHODS: From November 2001 to April 2004 we evaluated eight patients (3-17 years) with non-contrast CTC. Seven of the patients had CTC, followed by standard colonoscopy (SC) the same day; in one patient, CTC followed a failed SC. CTC results were compared to results of SC. The estimated effective dose from each CTC was calculated and compared to that of standard barium enema. RESULTS: CTC results were consistent with those of SC. Sensitivity for polyps 5-10 mm was 100%, and sensitivity for polyps 10 mm and larger was 66.7%. The estimated mean effective dose was 2.17 mSv for CTC, compared to the 5-6 mSv for a standard air-contrast barium enema in a small child. CONCLUSION: Our initial experience shows CTC in children is well-tolerated, safe, and useful. The procedure can be performed successfully with a low radiation dose, and preliminary results compare well with SC.

Pediatric magnetic resonance imaging techniques.

Optimization of the MR image requires an understanding of technical parameters, pulse sequences, artifacts, and the use of contrast agents. More technical information and in-depth details about the practical concepts for performing MRI in children can be found in the references accompanying this article.
