“…Other causes of second-order neuron Horner syndrome include neck or upper thoracic surgery; primary spinal nerve root tumors and lesions that compress the nerve roots, such as nerve root tumors or osteophytes; jugular venous ectasia; subclavian artery aneurysm; and other neck masses causing compression of the cervical sympathetic chain [22][23][24][25].…”

First described in 1727, Horner syndrome occurs from injury to one of the three neurons in the oculosympathetic pathway. Its presence can be confirmed with pharmacologic testing, traditionally including cocaine testing with hydroxyamphetamine localization. More recently, apraclonidine testing has become a viable alternative in some practices. Concern has been raised regarding the possibility of false-negative results with apraclonidine testing as well as the safety of its use in young children.

“…4,5 Anderson et al reported that 69% of patients who were found to have mycotic aneurysm were not known to have aortic coarctation prior to the onset of the infection, 1 highlighting the difficulty of this diagnostic challenge. Our patient is unique for multiple reasons, he had Streptococcus pneumoniae causing myostitis, 6 which has been reported but is uncommon, he had a unique early manifestation of the aneurysm, in the form of Horner's syndrome, 7,8 and he is the first reported case, to our knowledge, of this bacteria causing a mycotic aortic aneurysm.…”

Mycotic aneurysms are rare in patients with congenital heart disease, but may occur in those with aortic coarctation and abnormal aortic valve. Rapid diagnosis of mycotic aneurysm is of extreme importance given the significant reported incidence of morbidity and mortality across all age groups. Aortic aneurysm is uncommon before the second decade of life, and here we report a 10-year-old male patient with new diagnosis of aortic coarctation and bicuspid aortic valve, who developed a rapidly enlarging mycotic aneurysm from Streptococcus pneumoniae. Cardiac magnetic resonance imaging was crucial in making the diagnosis, as well as in follow-up.

“…There are numerous imaging approaches in the preoperative stage and also in the postoperative follow-up of patients with aortic coarctation. For anatomic assessment of the coarctation site and identification of collaterals, non-invasive magnetic resonance imaging/angiography and also CT angiography show an equal sensitivity to invasive catheter angiography and thus are widely used as follow up tool [26,27,28,29]; however for functional assessment, the estimation of pressure gradients across the (re)stenosis by direct catheter measurement or with the use of Doppler echocardiography remains mandatory. There is very few experience with the use of VEC-MR in coarctation patients [8,30,31,32].…”

Elimination of errors caused by first-order aliasing in velocity encoded cine-MR measurements of postoperative jets after aortic coarctation: in vitro and in vivo validation

et al. 2001

The aim of this study was to evaluate a velocity-encoded cine-MR (VEC-MR) sequence in measuring flow velocities up to two times the velocity encoding value (VENC) in a flow phantom and to validate the method for assessing poststenotic jet velocities in postoperative patients after aortic coarctation. In vitro, a flow phantom was used (0.5T; TR/TE: 51/8 ms, flip angle=30 degrees, FOV=280 mm, 128x256 matrix VENC 40 or 80 cm/s). On binary images, maximum flow velocities (V(max)) were calculated with a region of interest (ROI, 8 pixels). With aliasing, V(max) was calculated by VENC+(V(aliasing)). In vivo, 16 postoperative patients after aortic coarctation underwent double-oblique VEC-MR imaging through the aortic arch (ECG triggering, 16 phases/RR, TR=600-800 ms, flow-encoding cranio-caudal, VENC=2 m/s). Peak systolic velocities were measured and transthoracic Doppler echocardiography (TTDE) was performed. In vitro, there were excellent correlations for MR velocity measurements with and without aliasing ( r=0.99) and for true and MR-derived flow velocities ( r=0.99). In vivo, there was good correlation between VEC-MR and TTDE-assessed V(max) values in the aorta at the former coarctation site ( r=0.90, n=16). Aliasing occurred in 13 patients. VEC-MR is a useful modality for assessing jet velocities in the follow-up of patients after aortic coarctation. Despite of aliasing, accurate velocity measurements up to two times VENC are possible using binary images.
