Clinical Outcome of Magnetic Resonance Imaging-Detected Additional Lesions in Breast Cancer Patients

Purpose: The aim of this study was to investigate the clinical outcome of additional breast lesions identified with breast magnetic resonance imaging (MRI) in breast cancer patients. Methods: A total of 153 patients who underwent breast MRI between July 2006 and March 2008 were retrospectively reviewed. Thirty-three patients (21.6%) were recommended for second-look ultrasound (US) for further characterization of additional lesions detected on breast MRI and these patients constituted our study population. Results: Assessment for lesions detected on breast MRI consisted of the following: 25 benign lesions (73.5%), two indeterminate (5.9%), and seven malignant (20.6%) in 33 patients. Second-look US identified 12 additional lesions in 34 lesions (35.3%) and these lesions were confirmed by histological examination. Of the 12 lesions found in the 11 patients, six (50.0%) including one contralateral breast cancer were malignant. The surgical plan was altered in 18.2 % (six of 33) of the patients. The use of breast MRI justified a change in treatment for four patients (66.7%) and caused two patients (33.3%) to undergo unwarranted additional surgical procedures. Conclusion: Breast MRI identified additional multifocal or contralateral cancer which was not detected initially on conventional imaging in breast cancer patients. Breast MRI has become an indispensable modality in conjunction with conventional modalities for preoperative evaluation of patients with operable breast cancer

Deltoid detachment consequent to open surgical repair of massive rotator cuff tears

Deltoid detachment is one of the complications in open rotator cuff repair. Although it is often described, the actual prevalence, time at which it occurs and the predisposing causes are still unknown. We prospectively studied 112 patients with massive rotator cuff tears with a mean age of 67. The surgical approach was performed with a lateral para-acromial incision. Clinical assessment was performed with Constant’s method. Of the 112 patients, 9 (8%) had deltoid detachment. It occurred about 3 months after surgery. Of the nine patients, two underwent revision surgery for the deltoid trans-bone reattachment. At the follow-up, the patients with deltoid detachment had a mean increase of only 5.5 points in the Constant score compared to that of 16.9 obtained by the control group. Deltoid reattachment, performed on the two patients, provided a mean increase of 7 points only with respect to the post-operative control at the 4th month. Considering the unsatisfactory functional result consequent to deltoid detachment and the slight improvement obtained with the reattachment, we recommend the following: use suture thread thicker than #2, do not use a simple stitch and avoid extending acromioplasty to the lateral margin of the acromion
