Nodular fasciitis is a benign rapidly proliferating fibrous tumor that is common in adults but relatively uncommon in children. When present in children, nodular fasciitis is typically subcutaneous in location and involves the head and neck. We present a case of intramuscular nodular fasciitis involving the rectus abdominis muscle in an 11-year-old girl and discuss the importance of distinguishing this rare but benign lesion from a more aggressive sarcomatous process.

Background The balloon-assisted coil embolization (BACE) technique represents an effective tool for the treatment of complex wide-necked intracranial aneurysms; however, its safety is a matter of debate. This study presents the authors' institutional experience regarding the safety of the BACE technique. Methods 428 consecutive patients with 491 intracranial aneurysms (274 acutely ruptured and 217 unruptured) treated with conventional coil embolization (CCE) or with BACE were retrospectively reviewed. All procedure-related adverse events were reported, regardless of clinical outcome. Thromboembolic events, intraprocedural aneurysm ruptures, device-related complications, morbidity and mortality were compared between the CCE and BACE groups. Results The total rate of procedural and periprocedural adverse events was 9.6% (47/491 embolizations). Thromboembolic events, intraprocedural aneurysmal rupture and device-related complications occurred in 2.4%, 3.9% and 3.3% of procedures, respectively. The risk of thromboembolic events and device-related problems was similar between the CCE and BACE groups. A trend towards a higher risk of intraprocedural aneurysm rupture was observed in the BACE group (not statistically significant). The total cumulative morbidity and mortality for both groups was 2.6% (11/428 patients) and there was no statistically significant difference in the morbidity, mortality and cumulative morbidity and mortality rates between the two groups. Conclusion In this series of patients with acutely ruptured and unruptured aneurysms, the BACE technique allowed treatment of aneurysms with unfavorable anatomic characteristics without increasing the incidence of procedural complications.

Image de-identification has focused on the removal of textual protected health information (PHI). Surface reconstructions of the face have the potential to reveal a subject’s identity even when textual PHI is absent. This study assessed the ability of a computer application to match research subjects’ 3D facial reconstructions with conventional photographs of their face. In a prospective study, 29 subjects underwent CT scans of the head and had frontal digital photographs of their face taken. Facial reconstructions of each CT dataset were generated on a 3D workstation. In phase 1, photographs of the 29 subjects undergoing CT scans were added to a digital directory and tested for recognition using facial recognition software. In phases 2–4, additional photographs were added in groups of 50 to increase the pool of possible matches and the test for recognition was repeated. As an internal control, photographs of all subjects were tested for recognition against an identical photograph. Of 3D reconstructions, 27.5% were matched correctly to corresponding photographs (95% upper CL, 40.1%). All study subject photographs were matched correctly to identical photographs (95% lower CL, 88.6%). Of 3D reconstructions, 96.6% were recognized simply as a face by the software (95% lower CL, 83.5%). Facial recognition software has the potential to recognize features on 3D CT surface reconstructions and match these with photographs, with implications for PHI.

To the Editor: In reading the letter by Schwarz et al. (Oct. 24 issue), 1 we were impressed by the substantial difference between their findings and those that we reported in a 2012 study, 2 as cited by the authors. In matching facially rendered radiologic images to facial photographs, Schwarz et al. found that automated-recognition software made the correct match in 83% of cases using their data set of magnetic resonance images (MRIs), as compared with a match rate of 27.5% in our study, which used a computed tomographic (CT) data set. In comparing the two studies, we draw some tentative conclusions. . . .
