Increased 68Ga-FAPI Uptake of Ureteric Fibroepithelial Polyp and Costal Cyst Mimicking Malignancy With Bone Metastasis.

A 70-year-old man presented with progressive dysuria. 18F-FDG PET/CT showed no abnormal metabolic activity. 68Ga-FAPI PET/CT revealed intense 68Ga-FAPI in the lower left ureter and the left rib, mimicking malignancy with bone metastasis.

Benign Duodenal Leiomyoma Mimicking Malignancy on 68Ga-FAPI PET/CT.

We present PET/CT findings of a 62-year-old woman with duodenal leiomyoma. 18F-FDG PET/CT demonstrated a mass with mild FDG uptake at the duodenal papilla (SUVmax, 3.7).

Biceps Brachii Metastasis as the Initial Clinical Manifestation of Lung Squamous Cell Carcinoma: A Potential Pitfall in Patients With Nonrespiratory Symptoms.

Metastatic tumor in the biceps brachii as the initial manifestation of non-small cell lung cancer is exceedingly atypical. Herein, we present the case of a 69-year-old woman with a left biceps brachii mass as the initial presentation. 18F-FDG PET/CT revealed a lesion in the upper lobe of the left lung and the left biceps brachii mass with SUVmax of 9.

Mixed adeno-neuroendocrine carcinoma on dual-tracer 18 F-FDG and 68 Ga-DOTATATE PET/CT.

Tumor heterogeneity is not effortlessly detected. We present the case of a 66-year-old man with a history of rectal adenocarcinoma diagnosed four years ago, where mixed adeno-neuroendocrine carcinoma were identified via dual-tracer 18 F-FDG and 68 Ga-DOTATATE PET/CT. This case highlights the value of dual-tracer PET/CT imaging in assessing tumor heterogeneity and compensating for potential pathological sampling bias.

Three-dimensional printing of patient-specific plates for the treatment of acetabular fractures involving quadrilateral plate disruption.

Background: Complicated acetabular fractures comprise the most challenging field for orthopedists. The purpose of this study was to develop three-dimensional printed patient-specific (3DPPS) Ti-6Al-4 V plates to treat complicated acetabular fractures involving quadrilateral plate (QLP) disruption and to evaluate their efficacy.

Methods: Fifty patients with acetabular fractures involving QLP disruption were selected between January 2016 and June 2017.

Comparative biomechanical testing of customized three-dimensional printing acetabular-wing plates for complex acetabular fractures.

Background: Three-dimensional (3D) printing of an acetabular wing-plate is a new minimally invasive surgical technique for complex acetabular fractures.

Objectives: To investigate the biomechanical stability of 3D printing acetabular wing-plates. The results were compared with 2 conventional fixation systems.

Bioactive Glass-Polycitrate Hybrid with Osteogenetic Ability Comparable to Autogenous Bone.

Significant progress in artificial bone grafts has been achieved in recent years. However, none of them has osteogenic ability that is close to autogenous bones. Hence, improving osteogenic ability of artificial bone is the most prominent and challenging task in this field.

Internal fixation of acetabular fractures in an older population using the lateral-rectus approach: short-term outcomes of a retrospective study.

Purpose: This study aims to examine the clinical efficacy and surgical techniques of the lateral-rectus approach for treatment of acetabular factures in elderly patients.

Methods: After appropriate exclusion, 65 elderly patients with an acetabular fracture who was treated through the lateral-rectus approach from January 2011 and October 2016 were selected retrospectively. By analyzing the medical records retrospectively, the patients' characteristics, fracture type, mechanism of injury, comorbid conditions, ASA class, operative time, intra-operative blood loss, and post-operative complications were assessed.

A Single Lateral Rectus Abdominis Approach for the Surgical Treatment of Complicated Acetabular Fractures: A Clinical Evaluation Study of 59 Patients.

BACKGROUND This study aimed to evaluate outcome following a single lateral rectus abdominis surgical approach for complicated acetabular fractures, involving anterior and posterior columns. MATERIAL AND METHODS From January 2012 to March 2016, 59 patients, including 36 anterior column hemitransverse fractures, 18 two-column fractures, and five T-type complicated acetabular fractures, were treated with a single lateral rectus abdominis approach and fixed by plates and cannulated lag screws. Anterior column fractures were fixed with 3.

Biocompatibility of Bespoke 3D-Printed Titanium Alloy Plates for Treating Acetabular Fractures.

Treatment of acetabular fractures is challenging, not only because of its complicated anatomy but also because of the lack of fitting plates. Personalized titanium alloy plates can be fabricated by selective laser melting (SLM) but the biocompatibility of these three-dimensional printing (3D-printed) plates remains unknown. Plates were manufactured by SLM and their cytocompatibility was assessed by observing the metabolism of L929 fibroblasts incubated with culture medium extracts using a CCK-8 assay and their morphology by light microscopy.
