Leiomyoma: A rare cause of adrenal incidentaloma

A 40-year-old, treatment-naïve, human immunodeficiency virus- (HIV) positive male was found to have a large right adrenal incidentaloma on ultrasound of the abdomen, which was confirmed on adrenal computed tomography imaging. The laboratory workup excluded functionality of the mass lesion. As the radiological examination of the mass raised the suspicion of a non-benign lesion, the patient underwent a right adrenalectomy. Histology, supported by a panel of immunohistochemical stains, confirmed the diagnosis of an adrenal leiomyoma. Most of the reported cases of adrenal leiomyomas in the literature are of patients with HIV and/or latent Epstein-Barr virus infections. This case illustrates that benign tumours, such as leiomyomas, can mimic the imaging phenotype of adrenal cortical carcinomas, and should be included in the differential diagnosis of adrenal incidentalomas, especially in the HIV-positive population

Numerical Evaluation of the Elastic Properties of Carbon Fiber Reinforced Composite Material at Elevated and Lowered Temperatures

The effect of elevated and lowered temperatures on the elastic properties of carbon fiber-epoxy composite material was studied using multi-phase unit cell (MPUC) numerical model. Evaluation of the elastic properties of carbon fiber-epoxy composite material is based on the finite element method. Obtained results confirmed that elevated and lowered temperature has noticeable influence on elastic properties of carbon fiber-epoxy composite material. As demonstrated, this fact has considerable influence on accurate evaluation of generated thermal stresses in real laminated composite structures, exposed to extremely high or low operating temperatures
