Epiploic appendagitis is self-limited and spontaneously resolves without surgery within 5-7 days. Therefore, it is imperative for radiologists to be familiar with this entity.

By clearly defining the normal ligaments that contribute to the stability of the Lisfranc joint, MRI allows a more precise and correct diagnosis of the origin of the Lisfranc joint instability, perhaps permitting a more specific surgical management. MRI also allows a better understanding of the normal imaging anatomy of the different ligamentous components of the Lisfranc joint, mainly of the Lisfranc and plantar Lisfranc ligaments.

By clearly defining the normal ligaments that contribute to the stability of the calcaneocuboid joint, MRI allows a more precise and correct diagnosis of the etiology of the calcaneocuboid instability, perhaps permitting a more specific surgical management. MRI also allows a better understanding of the normal imaging anatomy of the different components of the ligamentous structures of the talocalcaneonavicular joint, particularly of the spring ligament complex.

We have described the detailed anatomy of the plantar aponeurosis with emphasis on the more distal structures that can be visualized with MRI. There was no statistically significant difference between the accuracy of ultrasonography and MRI regarding the measurements of the thickness of the central and lateral portions of the plantar aponeurosis. Knowledge of the normal anatomy of these structures enables the radiologist to identify early alterations, providing timely diagnosis and treatment.

Knee joint lesions can be solitary or occur concomitantly with other lower limb abnormalities. Ring-shaped lateral meniscus (RSM) and hypoplasic anterior cruciate ligament (ACL) are two rare malformations. The therapeutic management of such abnormalities is not consensual, and highly depends on clinical symptomatology. We report a case of a 25-year-old girl with progressive knee pain whose MRI demonstrated a continuous segment of lateral meniscus situated along the medial aspect of the lateral compartment, continuous with the otherwise normal-appearing lateral meniscus, compatible with an RSM. This anatomic variant can be mistaken by a displaced meniscal fragment, like a bucket-handle tear, a central tear of a discoid meniscus, or incomplete discoid meniscus, as previously reported. Her MRI examination also showed a thinned ACL with anomalous lateral course. This abnormality may be mistaken for an ACL rupture and/or a meniscofemoral ligament with agenesis of ACL. Multiple images in different planes as well as following the course of meniscal and ligaments are critical clues to avoid misdiagnosis. As a result, the diagnosis of an RSM along with hypoplasic ACL with abnormal attachment was assumed based on MRI and confirmed during arthroscopy. The patient was treated conservatively with clinical outcome improvement.

The biceps brachii muscle is prone to variants but absence of the long head of the biceps (LHB) tendon is an exceptionally rare anomaly. This report concerns the fourth case of bilateral congenital absence of the LHB tendon and presents the ultrasonography (US) and magnetic resonance (MR) findings. Our case has the peculiarity of being the first in which bilateral LHB tendon agenesis is not associated with rotator cuff or labral tears.

After removal of artefacts, the mean monitoring time was 22 h08 (8 h54). All patients had impaired cerebral autoregulation during their monitoring time. The mean IAR index was 17 (9.5) %. During H 0 H 6 and H 18 H 24 , the majority of our patients; respectively 53 and 71 % had an IAR index > 10 %. Conclusion According to our data, patients with septic shock had impaired cerebral autoregulation within the first 24 hours of their admission in the ICU. In our patients, we described a variability of distribution of impaired autoregulation according to time. ReferencesSchramm P, Klein KU, Falkenberg L, et al.
