Objectives. The aim of this study is to demonstrate the various imaging appearances of stromal fibrosis on mammography, ultrasound, and magnetic resonance imaging (MRI). Material and Methods. This study included 75 female patients who presented to the American University of Beirut Medical Center between January 2010 and October 2015 for breast imaging. 66 (88%) patients obtained a mammogram, 71 (95%) had an ultrasound, and 6 (8%) had an MRI. Patients included had stromal fibrosis proven on biopsy. Results. The most common finding on mammogram was calcifications which was present in 14 (21%) patients, while on ultrasound it was a mass which was present in 61 (86%) patients. A mass was detected on MRI in 2 (33.5%) patients. Most lesions detected had benign findings such as masses with circumscribed margins. We had a follow-up for 53 (71%) patients with an average follow-up interval of 28.5 months (range: 5 – 70). Increase in size of the index lesion was noted in only 2 patients; upon rebiopsy, pathology results read stromal fibrosis for one lesion and fibroadenoma for the other. The remaining lesions were either stable or decreased in size. The higher detection rate of a mass on ultrasound was statistically significant (p<0.001) in comparison to that of mammography. Conclusion. Stromal fibrosis can have various presentations on imaging from benign to suspicious for malignancy features. In the case of accurate targeted biopsy, when stromal fibrosis is diagnosed, the result can be considered concordant. Therefore, such lesions can be followed up by imaging to document stability and confirm benignity.

Background: There is a pressing need for robust longitudinal cohort studies in the modern treatment era of multiple sclerosis. Objective: Build a multiple sclerosis (MS) cohort repository to capture the variability of disability accumulation, as well as provide the depth of characterization (clinical, radiologic, genetic, biospecimens) required to adequately model and ultimately predict a patient’s course. Methods: Serially Unified Multicenter Multiple Sclerosis Investigation (SUMMIT) is an international multi-center, prospectively enrolled cohort with over a decade of comprehensive follow-up on more than 1000 patients from two large North American academic MS Centers (Brigham and Women’s Hospital (Comprehensive Longitudinal Investigation of Multiple Sclerosis at the Brigham and Women’s Hospital (CLIMB; BWH)) and University of California, San Francisco (Expression/genomics, Proteomics, Imaging, and Clinical (EPIC))). It is bringing online more than 2500 patients from additional international MS Centers (Basel (Universitätsspital Basel (UHB)), VU University Medical Center MS Center Amsterdam (MSCA), Multiple Sclerosis Center of Catalonia-Vall d’Hebron Hospital (Barcelona clinically isolated syndrome (CIS) cohort), and American University of Beirut Medical Center (AUBMC-Multiple Sclerosis Interdisciplinary Research (AMIR)). Results and conclusion: We provide evidence for harmonization of two of the initial cohorts in terms of the characterization of demographics, disease, and treatment-related variables; demonstrate several proof-of-principle analyses examining genetic and radiologic predictors of disease progression; and discuss the steps involved in expanding SUMMIT into a repository accessible to the broader scientific community.

Abstract POST TRANSPLANT BRENTUXIMAB MAINTENANCE APPEARS MORE EFFECTIVE THAN POST TRANSPLANT SALVAGE BRENTUXIMAB FOR RELAPSED /REFRACTORY HODGKIN LYMPHOMA Amanda Chidiac1, Radwan Massoud 1, Mohamad Haidar1, Elie Fares1, Ali Bazarbachi1 and Jean El Cheikh1 1Bone Marrow Transplantation Program, American University of Beirut Medical Center, Beirut, Lebanon Keywords: Hodgkin Lymphoma, Relapsed/Refractory, Brentuximab. Context: Brentuximab Vedotin (BV) is a chimeric anti CD30 IgG1 antibody, conjugated to synthetic antitubulin momomethyl auristatin. BV is approved for the treatment of classical HL in relapse either after autologous stem cell transplantation (ASCT) or after two lines of combination chemotherapy in transplant ineligible patients. The AETHERA trial revealed increased PFS when BV is used as maintenance therapy after ASCT. Objective: Compare the effectiveness of BV as maintenance or salvage therapy after ASCT for relapsed/refractory (R/R) HL. Design: A retrospective analysis conducted on patients with R/R HL treated with BV after ASCT either as maintenance or salvage therapy. Analysis after a median follow up of 12 months is reported. Setting: The study was conducted in a single institution; American University of Beirut Medical Center (AUBMC) after IRB approval. Patients: The study included 15 adult patients with R/R HL treated with BV with the following indications: á Maintenance therapy after ASCT in high risk patients á Salvage therapy for relapse after ASCT or allo-SCT Intervention: BV at 1.8mg/kg IV every 4 weeks for the above indications. Main outcome measures: response rate (RR), overall survival (OS) and progression free survival (PFS). Results: Nine high-risk patients (60%) received 4 cycles of BV as maintenance therapy post ASCT. Six additional patients (40%) in relapse after ASCT (n=5) or after allo-SCT (n=1) received BV as salvage therapy for an average of 4 cycles (range 3-21). Patients characteristics are listed on Table 1. RR was 33% in 6 patients who received BV as salvage post SCT. Two patients proceeded with allo-SCT in the salvage group. After a median follow up of 9 months, only 2 patients (22%) in the maintenance group progressed and all patients are still alive. Conversely, in the salvage group, 4 patients (67%) progressed and 1 patient developed secondary AML and died. Conclusion: BV therapy showed an efficacy only as maintenance treatment after auto-SCT but was less successful when used as post-transplant salvage in R/R HL. Four cycles of maintenance may suffice. Prospective trials with larger samples are warranted to support these findings. Disclosures No relevant conflicts of interest to declare.

Objectives: We analyzed the magnetic resonance imaging (MRI) manifestations of fetal corpus callosum abnormalities and discussed their prognosis based on the results of postnatal follow up. Methods: One hundred fifty-five fetuses were diagnosed with corpus callosum abnormalities by MRI at our hospital from 2004 to 2019. Gesell Development Scales were used to evaluate the prognosis of corpus callosum abnormalities after birth. Results: Corpus callosum abnormalities were diagnosed in 149 fetuses from singleton pregnancies, and 6 pairs of twins, 1 in each pair is a corpus callosum abnormality. Twenty-seven cases (27/155) were lost to follow up, whereas 128 cases (128/155) were followed up. Of these, 101 cases were induced for labor, whereas 27 cases were born naturally. Among the 27 cases of corpus callosum abnormality after birth, 22 cases were from singleton pregnancies (22/27). Moreover, 1 twin from each of 5 pairs of twins (5/27) demonstrated corpus callosum abnormalities. The average Gesell Development Scale score was 87.1 in 19 cases of agenesis of the corpus callosum and 74.9 in 3 cases of hypoplasia of the corpus callosum. Among the 5 affected twins, 2 had severe neurodevelopmental delay, 2 had mild neurodevelopmental delay, and 1 was premature and died. Conclusion: The overall prognosis of agenesis of the corpus callosum is good in singleton pregnancies. Hypoplasia of the corpus callosum is often observed with other abnormalities, and the development quotient of hypoplasia of the corpus callosum is lower compared with agenesis of the corpus callosum. Corpus callosum abnormalities may occur in one twin, in whom the risk may be increased.

The increasing use of radiological examination, especially magnetic resonance imaging (MRI), will probably increase the risk of unintended discovery of bone marrow abnormalities in patients where a hematologic disease would not be expected. In this paper we present four patients with different hematologic malignancies of nonplasma cell types. In all patients the MRI bone marrow abnormalities represent an initial presentation of the disease. These case reports illustrate the importance of a careful diagnostic follow-up without delay of patients with MRI bone marrow abnormalities, because such abnormalities can represent the first sign of both acute promyelocytic leukemia as well as other variants of acute leukemia.

Targeted Biopsies

Introduction. Significant improvement in the quality of visualization of the prostate using magnetic resonance imaging (MRI), as well as the development of technologies for virtual combination of MRI and ultrasound images opens new horizons in the diagnosis of prostate cancer. The introduction of the PI-RADS system has allowed the standardization of MRI findings, and the development of fusion biopsy systems seeks to make diagnostics more accurate and less operator-dependent. Materials and methods. In this literature review, we evaluate the effectiveness of various biopsy approaches and discuss the prospects for targeted biopsies. The search for publications was carried out in the databases PubMed, e-library, Web of Scince et al. For citation, 55 literature sources were selected that met the search criteria for the keywords, «prostate cancer», «biopsy», «MRI», «TRUS», «fusion». Results. Diagnosis of prostate cancer using MRI. Modern technologies for radiological diagnosis of prostate cancer using magnetic resonance imaging (MRI) are based on the standardized PI-RADS protocol, using different modes (T2, diffusion-weighted images and contrast enhancement), which provides the best visualization of tumor-suspicious nodes in the prostate gland, allowing determination of lesion localization and size for subsequent targeted biopsy. Options for performing a prostate biopsy to diagnose prostate cancer. A description of the methods and effectiveness of transrectal and transperineal biopsy under ultrasound guidance is carried out - due to the fact that ultrasound diagnostics of prostate cancer has a rather low sensitivity due to small differences in the ultrasound structure of normal and tumor tissue of the prostate, an extended template biopsy technique was proposed, which involves puncture of the prostate through a special lattice. It also describes the technology of fusion biopsy and also provides literature data comparing the diagnostic accuracy of standard TRUS and fusion prostate biopsy, as well as the importance of transrectal / transperineal access. Questions for further study. Given the desire to reduce the number of biopsies while maintaining or even increasing the accuracy of diagnosing prostate cancer, data from studies investigating the feasibility of combining polyfocal (non-targeted) and targeted (targeted) biopsies are presented. Conclusion. The existing methods of non-targeted biopsy (polyfocal, saturation, template) and targeted (fusion biopsy) have their advantages and disadvantages, which currently do not allow making certain recommendations for their use, but a significant number of authors prefer MRI-as sisted, fusion -biopsy.

Short-lasting unilateral neuralgiform headache with autonomic symptoms (SUNA) is a rare form of trigeminal autonomic cephalalgia. SUNA is frequently associated with a trigeminal neurovascular conflict and rarely occurs secondary to other intracranial pathology. We report a patient with SUNA that was associated with ipsilateral meningeal inflammation caused by idiopathic hypertrophic pachymeningitis (HP). During the 9-year follow-up, she experienced multiple episodes of SUNA, most of which occurred during exacerbations of the pachymeningitis. This is the third case of SUNA associated with HP reported in the literature. Based on this observation, we suggest that in patients presenting with SUNA, besides dedicated magnetic resonance imaging (MRI) of the trigeminal nerve, gadolinium-enhanced brain MRI should be performed to rule out HP.
