RESUMO
This descriptive study was performed on individuals who were referred to Imam Reza Hospital for fine needle aspiration biopsy (FNAB) based on the results of gray scale ultrasound and the decision of the referring physician. In addition to determining the gray scale characteristics of the nodules, shear wave elastography (SWE) was also performed and the results were recorded. These were also taken from the patients FNAB results. Finally, the findings of SWE and FNAB methods were compared and analyzed using SPSS software version 16. Based on the results presented herein, a significant relationship was observed between the results of SWE and FNA in the diagnosis of malignancy in solid thyroid nodules. This agreement was found to be higher in men (K = 0.866) than women (K = 0.849). Taken together, our data suggest that shear wave elastography can replace FNA in the diagnosis of malignancy in solid thyroid nodules.
RESUMO
Epignathus is a rare congenital orofacial teratoma. Teratomas are tumors that originate from all three germs cell layers. Tumor size is an important prognostic factor, and we describe the case of massive epignathus identified by sonography at 25 weeks. Our case was a 35-year-old pregnant woman that was subjected to a routine ultrasound at 25 weeks of gestation, and epignathus was diagnosed. Labor pain started in the 28th week of the pregnancy, so the dead fetus was aborted, and curettage was conducted. A pathologic sample was sent to the laboratory, and benign teratoma was diagnosed. Because fetal epignathus has a wide range of outcomes, early prenatal diagnosis is essential for optimal management.
