We describe a case of an anteromedial fracture-dislocation of the radial head in an adult patient, which was initially irreducible using closed means, and remained challenging to reduce despite open surgery. Further advanced CT/MRI revealed entrapment of the radial head due to the interposition of the brachialis tendon posteriorly, thereby preventing sustained reduction. While three other cases of irreducible anteromedial radial head dislocation due to the brachialis tendon have been reported in the English surgical literature, none of the imaging findings have been described in the radiological literature. Only one other case published in a surgical journal briefly demonstrated pre-operative MRI imaging. We would like to share the value of pre-operative MRI in this rare presentation, which would be helpful in diagnosing not only cases with interposition of the brachialis tendon, but potentially other types of soft tissue interposition which also limit closed reduction. To the best of the authors’ knowledge, this would be the first report on the imaging findings in a radiological journal. Awareness of this phenomenon would assist radiologists in the diagnosis and management of this rare condition.

Interhemispheric Cyst

Asymmetric ventriculomegaly, interhemispheric cyst and dysgenesis of the corpus callosum (AVID) constitutes a rare imaging triad. Additional findings include subcortical and subependymal heterotopia, polymicrogyria, fused thalami, deficient falx, and hydrocephalus. The knowledge of this triad helps us to diagnose prenatally by sonography and fetal MRI. In this case report authors present MRI Imaging findings in a case of AVID syndrome in a 6year old male child presenting with history of seizures and delayed milestones.

Solitary Extramedullary Plasmacytoma

Solitary plasmacytoma (SP) is a malignant tumor caused by the monoclonal proliferation of plasma cells, representing less than 5% of plasma cell tumors. SP can be categorized into two groups: solitary bone plasmacytoma (SBP) and solitary extramedullary plasmacytoma (SEP). SEP most commonly occurs in the head and neck and is rarely located in the reproductive system. Here, we report a case of a 77-year-old woman with SEP in the cervix who had a 7-day history of vaginal bleeding. Ultrasonography and magnetic resonance imaging (MRI) showed an oval mass in the cervix, which was initially considered as neoplastic lesions and highly suspected to be cervical cancer, but cervical leiomyoma and other benign tumors cannot be completely excluded. Subsequently, cervical biopsy showed that the tumor was SEP, and then the patient underwent surgery. The postoperative pathological diagnosis was also SEP, which confirmed the radiologist’s misjudgment. In conclusion, SEP that occurs in the cervix is remarkably rare, and only nine cases have been reported in the cervix. No case reports to date have described in detail the imaging findings of cervical SEP. This study demonstrates the MRI imaging characteristics of a patient with SEP of the cervix and reviews the imaging findings of SEP reported in the previous literature, in order to provide more extensive insights for radiologists to consider the differential diagnosis of cervical lesions.

Abstract P383: AI-Guided Detection and Volumetric Analysis of Embolic and Watershed Infarcts on Diffusion-Weighted MRI Enables Measurement of the Absolute and Relative Ischemic Infarct Burden

Watershed Infarcts

Acute ischemic strokes frequently present with multiple restricted diffusion lesions scattered throughout the brain parenchyma, particularly embolic and watershed infarcts. The morphological variety and complexity of such infarcts are high in terms of their potential number, shape, volume, and spatial distribution. In current clinical practice, there is a limited description of the burden and variability of such infarcts. Here, we demonstrate an artificial-intelligence guided approach using high-performance computing, for the fast (minutes) and precise (sub-milliliter) detection and quantification of each infarcted brain volume regardless of size and morphology. Our methodology is based on processing and analyzing the original DICOM data by filtering, segmentation, and morphological neighborhood operations to identify and triage 3D-connected volumes of interest that represent ischemic stroke. Figure Panel A shows the analysis of a watershed stroke with the identification of 5 ischemic subvolumes with an overall infarct volume of 23.6 ml and a relative infarct volume of 2.0 % of the total brain volume of 1152 ml. In contrast, Figure Panel B shows the analysis of an embolic stroke with the identification of 20 ischemic subvolumes with an overall infarct volume of 51.6 ml and a relative infarct volume of 4.4 % of the total brain volume of 1178 ml. What is novel here is that our approach allows for the immediate measurement of the absolute (in ml) and relative (in terms of % of total brain volume) infarct burdens of complex strokes on initial MRI imaging. Volumetric analysis of stroke may represent a critical future biomarker. We suggest that such an approach might be easily implemented into clinical and research settings to guide clinical diagnoses, therapeutic decisions, and outcome prediction.
