Unusual Presentation of Widely Metastatic Extraskeletal Osteosarcoma: Case Report.

Extraskeletal osteosarcoma is a highly aggressive malignant osteoid forming mesenchymal neoplasm arising from soft tissues which accounts for 1% of all soft tissue sarcomas. We report the case of a 46-year-old female with no significant past medical history presenting to an emergency department with a right lateral thigh mass following minor trauma. She was eventually found to have high grade extraskeletal osteosarcoma with rapid progression of disease resulting in patient demise. Differentiation of these lesions from alternative processes relies on specific imaging and pathologic features. Differential diagnoses include both benign and malignant etiologies such as myositis ossificans, soft tissue hemangiomas, and other malignant soft tissue neoplasms such as epithelial and synovial sarcoma.

Implementation of 3D Printing in Medical Care for Preoperative Planning of Complex Ventricular Septal Defect.

Three-dimensional (3D) modeling and printing in medicine have emerged to encompass every aspect of medical applications. This ranges from education, illustration, and treatment, as well as patient care whether for purposes of diagnosis or treatment and surgical planning. In the past few decades, these novel tools have shown promising utility to help radiologists and the medical team to improve quality of patient care and outcomes via 3D printing application and utilization. This workflow will be illustrated through a ventricular septal defect (VSD) case at which 3D analysis was critical in the assessment and treatment planning of the patient's underlying medical condition.

Emphysematous Aortitis due to Klebsiella Pneumoniae in a Patient With Poorly Controlled Diabetes Mellitus.

Patients with poorly controlled diabetes mellitus and an infectious source can be predisposed to infectious aortitis.

High metabolic tumor volume is associated with decreased efficacy of axicabtagene ciloleucel in large B-cell lymphoma.

High metabolic tumor volume (MTV) predicts worse outcomes in lymphoma treated with chemotherapy. However, it is unknown if this holds for patients treated with axicabtagene ciloleucel (axi-cel), an anti-CD19 targeted chimeric antigen receptor T-cell therapy. The primary objective of this retrospective study was to investigate the relationship between MTV and survival (overall survival [OS] and progression-free survival [PFS]) in patients with relapsed/refractory large B-cell lymphoma (LBCL) treated with axi-cel. Secondary objectives included finding the association of MTV with response rates and toxicity. The MTV values on baseline positron emission tomography of 96 patients were calculated via manual methodology using commercial software. Based on a median MTV cutoff value of 147.5 mL in the first cohort (n = 48), patients were divided into high and low MTV groups. Median follow-up for survivors was 24.98 months (range, 10.59-51.02 months). Patients with low MTV had significantly superior OS (hazard ratio [HR], 0.25; 95% confidence interval [CI], 0.10-0.66) and PFS (HR, 0.40; 95% CI, 0.18-0.89). Results were successfully validated in a second cohort of 48 patients with a median follow-up for survivors of 12.03 months (range, 0.89-25.74 months). Patients with low MTV were found to have superior OS (HR, 0.14; 95% CI, 0.05-0.42) and PFS (HR, 0.29; 95% CI, 0.12-0.69). In conclusion, baseline MTV is associated with OS and PFS in axi-cel recipients with LBCL.

Leiomyosarcoma of the Inferior Vena Cava with Hepatic and Pulmonary Metastases: Case Report.

Sarcomas are connective tissue tumors accounting for only 1% of all adult malignancies. Leiomyosarcoma (LMS) is a sarcoma arising from smooth muscle cells, and accounts for 10-20% of all sarcomas. A subtype of LMS are those originating from the smooth muscle of blood vessels. Leiomyosarcoma of the inferior vena cava is a sarcomatous tumor, with less than 350 cases described in the literature. It carries a poor prognosis, with 5- and 10-year survival rates of 31.4% and 7.4%, respectively. We present a case of a 46-year-old female with no significant past medical history presented to the emergency department with mild abdominal pain and distention, early satiety, and weight loss for three weeks, found to have unresectable metastatic leiomyosarcoma of the inferior vena cava.

Microgallbladder: Self-Remitting Acute Cholecystitis-Like Condition Unique to Patients with Cystic Fibrosis.

Microgallbladder is a nonsurgical medical condition characterized by chronic inflammation and atrophy of the gallbladder, which is considered a highly specific imaging finding unique to patients with cystic fibrosis (CF), and has been incidentally reported on abdominal imaging in up to 45% of cases with CF. The impairment of exocrine water efflux in CF leads to the production of hyperviscous biliary secretions, cholestasis, and transient cystic duct obstruction of the microgallbladder causing microcholecystitis-interestingly a self-remitting acute cholecystitis-like condition without surgical intervention. We present a case report of a 22-year-old male patient with history of CF with multiple hospital admissions for unexplained chronic abdominal pain found to be caused by microgallbladder, which was managed conservatively.

Numerical Correlation of Levator Advancement in Preoperative Planning.

BACKGROUND: Several procedures have been proposed for the treatment of eyelid ptosis, and both levator advancement and levator plication are widely used to shorten the levator palpebrae superioris. The purpose of this study was to quantify perioperative lid measurements in patients undergoing bilateral levator aponeurosis advancements to aid in preoperative planning. METHODS: Between July 2014 and June 2016, the authors performed a retrospective analysis of all bilateral upper eyelid levator advancement procedures for ptosis performed by the senior surgeon. There are a total of 21 patients (6 men and 15 women) with a mean age of 63 years (range, 48-79 years). The average time at follow-up was 5.3 months, with a range of 1 to 26 months. RESULTS: In this retrospective study, we collected data on presurgical measurements including marginal reflex distance 1 (MRD1), surgical technique used (symmetrical/asymmetrical levator advancement) with millimeters of advancement used, and postsurgical measurements. We found that on average, an advancement of 4 mm led to an improvement in MRD1 of 2.26 mm (n = 14), and advancement of 5 mm led to an improvement in MRD1 of 2.74 mm (n = 15). Patients also reported improvements in their quality of life. CONCLUSIONS: Our results may be used to guide clinicians in preoperative planning.

A Formula for Planning and Predicting Postoperative Mammoplasty Results.

PURPOSE: For women with macromastia, reduction mammoplasty is a safe and effective solution to increasing quality of life through alleviating pain and improving aesthetics. This study developed a way to combine a surgeon's view of breast measurement (volume) with a patient's view of breast measurement (distance between nipple and notch, inframammary fold, or midline) to provide patients with a better understanding of expected surgical outcomes after breast reduction with a medial superior pedicle. PATIENT AND METHODS: An institutional review board approved retrospective chart review was performed on all medial superior pedicle reduction mammoplasties performed by a single surgeon at a university medical center from 2008 to 2016, and a total of 133 patients were identified. Measurements of interest for this study were nipple to sternal notch (N-S), nipple to inframammary fold (N-I), nipple to midline (N-M), and breast diameter (BD). The average bilateral change per measurement was calculated for each patient in centimeters. Change was averaged for left and right breasts for N-S, N-I, N-M, and BD per patient. Grams removed for left and right breasts were also averaged. Each measurement of average change was divided by the gram average and multiplied by 100 to obtain centimeter change per 100 grams. Individual patient measurements per type of measurement were averaged to achieve a final improvement reported in centimeters per 100 g tissue removed per breast. RESULTS: The average change in the N-S distance was calculated to be a decrease of 1.5 ± 0.8 cm/100 g of breast tissue removed. The average change in N-I was calculated to be an overall decrease of 0.7 ± 0.5 cm/100 g. The average change in N-M was calculated to be a decrease of 0.1 ± 0.3 cm/100 g. Finally, the average change in BD was calculated to be 0.0 ± 0.4 cm/100 g. CONCLUSIONS: A surgeon's expression of breast measurements in terms of volume can be difficult for a patient to understand and visualize. This study determined the impact volume has on length of typical breast measurements to increase patients' understanding of expected outcomes. In summary, patients can be told to expect to see a nipple elevation of 1.5 cm per 100 grams of breast tissue removed using this medial superior pedicle technique.
