Investigating Injuries to the Anterolateral Corner of the Knee: Imaging Insights Into Kaplan Fibers and the Anterolateral Ligament in Anterior Cruciate Ligament Tears.

Background: The intricate relationship between anterolateral ligament (ALL) and Kaplan fibers (KF) injuries in acute traumatic anterior cruciate ligament (ACL) tears presents a diagnostic challenge. Understanding these associations is crucial for enhancing therapeutic strategies and patient outcomes.

Purpose: To elucidate the prevalence of ALL and KF injuries among patients with acute ACL tears and examine their correlations with other imaging findings.

A Bilateral Wolffian Adnexal Tumor with Malignant Behavior: A Rare Case Report with Literature Review.

Wolffian adnexal tumors (FATWOs) originate from the mesonephric duct remnants. FATWOs are extremely rare and 100 incidental FATWOs have been reported in the English literature as of now. Most FATWOs have low potential for malignancy but aggressive behavior including recurrence and metastasis have been described in few cases; There is no standard protocol for optimal treatment of FATWOs.

A Case of Primary Ovarian Primitive Neuroectodermal Tumor.

Primitive neuroectodermal tumors (PNET) are a family of poorly differentiated malignant neoplasms of neuroectodermal origin. According to the location of origin, PNETs could be further categorized as central or peripheral. Peripheral PNET (pPNET) is an uncommon type that accounts for 1% of all soft tissue sarcomas and occurs outside the central and sympathetic nervous systems.

Early diagnosis of impending rupture uterus during U/S: A case report.

Introduction And Importance: Uterine rupture is a rare condition that typically occurs in a scarred uterus and can happen during late pregnancy, labor, or the early postpartum period. Since most cases are seen in patients with a history of cesarean surgery, the anterior lower uterine segment is the most affected area. Most patients present with acute symptoms that compromise the fetus and the mother in a life-threatening manner.

A case report on pulmonary metastasis of giant cell tumor mimicking arteriovenous malformation.

Giant cell tumor (GCT) is typically a benign tumor of the skeletal system that mainly presents with bone pain. Pulmonary metastasis is one of the distant presentations of GCT in patients who have previously undergone surgical resection of the tumor. Among the various presentations of pulmonary metastasis in GCT, lesions with arteriovenous malformation (AVM) features are rare and have only been reported in a few cases.

Concomitant septic arthritis of the hip joint and femoral head avascular necrosis in patients with recent COVID-19 infection: a cautionary report.

Purpose: At present, concomitant avascular necrosis (AVN) of femoral head and septic arthritis (SA) as a sequel of COVID-19 infection has yet not been documented. By large-scale use of life-saving corticosteroids (CS) in COVID-19 cases, our aim is to warn of the occurrence of hip joint infection in these patients.

Methods: We report a series of five cases in which patients developed septic arthritis concomitant with AVN after being treated for COVID-19 infection.

Comparison of Qualitative (Time Intensity Curve Analysis), Semi-Quantitative, and Quantitative Multi-Phase 3T DCEMRI Parameters as Predictors of Malignancy in Adnexal.

Objective: The present study aimed to compare the qualitative (time intensity curve analysis), the semi-quantitative and the quantitative multiphase 3T dynamic contrast-enhanced (DCE) MRI parameters as predictors of malignancy in adnexal masses. Materials and Methods: In this prospective study, women with an adnexal mass who were scheduled for surgical resection or were followed for more than one year period to confirm the benignity of their lesions, underwent multiphase 3T DCE-MRI. The qualitative (time intensity curve), semi-quantitative (SImax, SIrel, WIR) and quantitative (Ktrans, Kep, Vb) analyses were performed on DCE-MRI sequences and their predictive values were compared.

Differentiation of Benign from Malignant Adnexal Masses by Dynamic Contrast-Enhanced MRI (DCE-MRI): Quantitative and Semi-quantitative analysis at 3-Tesla MRI.

Background: To evaluate the utility of the pharmacokinetic modeling derived from dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in differentiating benign from malignant adnexal masses. Methods: A total of 43 patients with 49 complex adnexal masses (27 benign, 3 borderline, and 19 malignant lesions) underwent preoperative DCE-MRI examinations on a 3 Tesla MRI. Using extended Tofts’ model, quantitative analysis was performed in the solid components of all tumors.

A one-step biomarker quantification methodology for DCE-MRI of adnexal masses: Capturing kinetic pattern from early to late enhancement.

Purpose: To develop a one-step quantification approach that accounts for joint preprocessing and quantification of whole-range kinetics (early and late-phase washout) of dynamic contrast-enhanced (DCE) MRI of indeterminate adnexal masses.

Methods: Preoperative DCE-MRI of 43 (24 benign, 19 malignant) sonographically indeterminate adnexal masses were analyzed prospectively. A five-parameter sigmoid function was implemented to model the enhancement curves calculated within regions of interest.

Semiquantitative dynamic contrast-enhanced MRI for accurate classification of complex adnexal masses.

Purpose: To identify the best dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) descriptive parameters in predicting malignancy of complex ovarian masses, and develop an optimal decision tree for accurate classification of benign and malignant complex ovarian masses.

Materials And Methods: Preoperative DCE-MR images of 55 sonographically indeterminate ovarian masses (27 benign and 28 malignant) were analyzed prospectively. Four descriptive parameters of the dynamic curve, namely, time-to-peak (TTP), wash-in-rate (WIR), relative signal intensity (SI ), and the initial area under the curve (IAUC ) were calculated on the normalized curves of specified regions-of-interest (ROIs).

A simple risk score for early ischemic stroke mortality derived from National Institutes of Health Stroke Scale: a discriminant analysis.

Objectives: The aim of the current study was to design a new simpler form of National Institutes of Health Stroke Scale (NIHSS) for use in emergency settings, and compare its predictive ability with original NIHSS score for mortality.

Methods: A total of 152 consecutive patients with first ever ischemic stroke admitted to a university affiliated hospital were recruited. NIHSS score on admission was estimated and the predictive ability of NIHSS items for mortality at 28 days was evaluated by logistic regression.

The underlying factor structure of National Institutes of Health Stroke scale: an exploratory factor analysis.

The underlying structure of National Institutes of Health Stroke Scale (NIHSS) as the most widely used scale in clinical trials has been the focus of little attention. The aim of the current study was to elucidate the clustering pattern of NIHSS items in ischemic stroke patients. A series of 152 consecutive patients with first-ever ischemic strokes admitted to a university affiliated hospital were enrolled.
