Abstract Objective: The objective of this study was to determine the incidence of a "meniscoid" superior labrum. Materials and Methods: This was a retrospective analysis of 582 magnetic resonance imaging examinations of shoulders. Of those 582 examinations, 110 were excluded, for a variety of reasons, and the final analysis therefore included 472 cases. Consensus readings were performed by three musculoskeletal radiologists using specific criteria to diagnose meniscoid labra. Results: A meniscoid superior labrum was identified in 48 (10.2%) of the 472 cases evaluated. Arthroscopic proof was available in 21 cases (43.8%). In 10 (47.6%) of those 21 cases, the operative report did not include the mention a superior labral tear, thus suggesting the presence of a meniscoid labrum. In only one of those cases were there specific comments about a mobile superior labrum (i.e., meniscoid labrum). In the remaining 11 (52.4%), surgical correlation demonstrated superior labral tears. Conclusion: A meniscoid superior labrum is not an infrequent finding. Depending upon assumptions and the requirement of surgical proof, the prevalence of a meniscoid superior labrum in this study was between 2.1% (surgically proven) and 4.8% (projected). However, superior labral tears are just as common and are often confused with meniscoid labra.

ABSTRACT Objective To improve the magnetic resonance imaging (MRI) and magnetic resonance arthrogram (MRA) interpretation of a ‘meniscoid-type’ superior labrum vs a superior labral tear by evaluation of a simple sign. Materials and methods Retrospective analysis of our institution's shoulder MRIs and MRAs yielded 144 patients thought to have a superior labral tear. Fifty-five patients had arthroscopy. Analysis of the orthopaedic database for superior labral repair surgeries performed in the same time frame yielded seven additional patients without prospective MRI/MRA diagnosis of superior labral tear. Results Two of 17 (11.8%) patients thought to have superior labral tears by MRI or MRA were found to have no labral pathology at arthroscopy. Both cases failed to have extension of high signal intensity behind the biceps anchor to the most posterior oblique coronal image. Nine of 38 (23.7%) patients thought to have superior labral tears by MRI or MRA were found to have no labral pathology at arthroscopy, but a meniscoid-type superior labrum. Four of seven patients known to have superior labral tears by arthroscopy but incorrectly diagnosed as meniscoid-type superior labrum on MRI or MRA, were retrospectively found to have extension of high signal intensity in the superior labrum to the most posterior image. Conclusion Signal abnormality that continues through the remainder of the superior labrum posterior to the biceps anchor indicates a superior labral tear. Absence of this sign in the setting of more anterior high signal under the labrum may indicate a meniscoid variant. Manvar AM, Bhalani SM, Garrigues GE, Major NM.

A Prospective Study

Retinal hemorrhages occur frequently in association with abusive head trauma.1 The injuries are venous [See table in the PDF] in origin and, as such, are similar to the retinal hemorrhages which frequently occur in full-term neonates after vaginal delivery. Because retinal hemorrhages in child abuse frequently are associated with intracranial bleeding, we questioned the possibility of a relationship between parturitional retinal hemorrhages and concurrent intracranial injuries. To answer this question we designed a prospective study in which we performed magnetic resonance imaging on 10 randomly selected full-term neonates in whom the presence of retinal hemorrhages was confirmed on fundascopic examination by a pediatric ophthalmologist.
