Case: A 34-year-old man presented at our hospital with knee collapse. Magnetic resonance imaging (MRI) revealed posterior compression of the dural sac by a lumbar epidural lesion; however, a diagnosis could not be reached. Gadolinium (Gd)-enhanced 3-dimensional MRI (3D-MRI) clearly delineated the morphology, enabling us to make a preoperative diagnosis of posterior epidural migration of the lumbar disc fragment (PEMLDF).

LCTs may demonstrate various clinical manifestations - from asymptomatic intratesticular swelling through nonspecific symptoms such as loss of libido, impotence or infertility, up to feminizing or virilizing syndromes due to hormonal activity of the tumor. This article presents a case of Leydig cell tumor that was associated with azoospermia what have rarely been reported worldwide.

Objectives: To assess the ability of a previously trained deep-learning algorithm to identify the presence of inflammation on MRI of sacroiliac joints (SIJ) in a large external validation set of patients with axial spondyloarthritis (axSpA).
Methods: Baseline SIJ MRI scans were collected from two prospective randomised controlled trials in patients with non-radiographic (nr-) and radiographic (r-) axSpA (RAPID-axSpA: NCT01087762 and C-OPTIMISE: NCT02505542) and were centrally evaluated by two expert readers (and adjudicator in case of disagreement) for the presence of inflammation by the 2009 Assessment of SpondyloArthritis International Society (ASAS) definition. Scans were processed by the deep-learning algorithm, blinded to clinical information and central expert readings.
Minimally Invasive Puncture and Drainage Surgery for the Treatment of Thalamic Hemorrhage Guided by a 3D-printed Guide Plate.

Thalamic hemorrhage is a type of intracerebral hemorrhage with high disability and mortality rates. Because of its deep bleeding location, irregular shape of the hematoma, and compression of the third ventricle, it is not suitable for craniotomy. This paper reports a case of a 63-year-old male patient who sought medical attention for left-sided basal ganglia and thalamus hemorrhage that broke into the ventricles.

Increased use of arthroscopically assisted techniques for the treatment of ankle fractures has been reported. Despite their rapid development, there is only one systematic review regarding arthroscopically assisted treatment of ankle fractures, in which, however, only malleolar fracture studies are included. Various other types of ankle fractures have also been treated with arthroscopically assisted procedures.
