RESUMEN
Abstract Introduction Jet aircraft pilots are exposed to huge pressure variation during flight, which affect physiological functions as systems, such as the respiratory system. Objectives The objective of the present investigation was to evaluate inflammatory changes of paranasal sinuses of jet aircraft pilots before and after a jet aircraft training program, using multislice computed tomography (CT), in comparison with a group of nonairborne individuals with the same age, sex, and physical health conditions. A second objective of the present study was to assess the association between the ostiomeatal complex obstruction and its anatomical variations. Methods The study group consisted of 15 jet aircraft pilots participating in the training program. The control group consisted of 41 nonairborne young adults. The 15 fighter pilots were evaluated before initiating the training program and after their final approval for the presence of inflammatory paranasal sinus disease. The ostiomeatal complex anatomical variations and obstructions were analyzed in pilots after the training program. Results Jet aircraft pilots presented higher incidence of mucosal thickening in maxillary sinus and anterior ethmoid cells than controls. Prominent ethmoidal bulla showed significant association with obstruction of the osteomeatal complex. Conclusions Jet aircraft pilots present increased inflammatory disease when compared with nonairborne individuals. The presence of a prominent ethmoidal bulla is associated with ostiomeatal complex obstruction.
RESUMEN
Hemangiomas são tumores vasculares benignos raros na mama. São de origem extraparenquimal e desenvolvem-se no tecido celular subcutâneo. O diagnóstico por exames de imagem pode ser difícil já que não apresentam características específicas, podendo ser confundidos com tumores malignos. Relatamos nesse artigo o caso de uma paciente portadora de hemangioma mamário em que a mamografia de rastreamento inicialmente demonstrou resultado inconclusivo, havendo necessidade de complementação diagnóstica com exame clínico e ultrassonografia para o laudo final de achados benignos (BI-RADS 2)
Hemangiomas are rare benign vascular tumors in the breast. They have extra parenchymal developing in the subcutaneous cellular tissue. Diagnosis by imaging exams can be difficult since this type of benign tumor does not have specific characteristics and can be confused with malignant tumors. We report in this article the case of a patient with breast hemangioma on screening mammography who initially had inconclusive result requiring clinical examination and ultrasound for the final report of benign findings (BI-RADS 2)
