Traumatic ocular injuries are common cause of emergency room visits. Injuries of the globe are a significant cause of blindness and visual deficits. The clinical assessment of globe trauma can be challenging. Some diagnoses can be made clinically, but imaging assessment is often required to determine associated lesions. Computed tomography (CT) allows the timely diagnosis of traumatic injuries of the globe, especially the presence of foreign bodies. In addition, knowledge of the imaging findings in other ocular pathologies that can be confused with traumatic pathologies is important to make an adequate differential diagnosis. The aim of this article is to carry out a review of imaging findings of traumatic ocular injuries.

Pulmonary nodules and masses are traditionally biopsied under computed tomography (CT) guidance. Ultrasound remains underrated as lung nodule biopsy guide. Ultrasound can be employed to target pleural based lung nodules. Specific con-traindications include: mechanical ventilation, contralateral pneumonectomy, non-cooperative patient and uncontrollable coughing. Post procedural care should cover vital signs check, pain assessment and complication evaluation. Due to lesion localization, complications such as pneumothorax and parenchymal bleeding are less frequent than in CT guided biopsies. In this article we provide basic concepts for patient selection, plan and safe execution of ultrasound guided pulmonary nodule biopsy.

The objective of this brief communication is to characterize the relevant tomographic aspects in the heterotaxy syndrome, by means of 4 patients that exemplify the most frequent findings in this pathology. Situs solitus is the usual arrangement of organs and blood vessels and situs inversus refers to the mirror image of situs solitus. When the arrangement of the organs is indeterminate and unpredictable and does not correspond to situs solitus or the situs inversus, we are facing the situs ambiguus or heterotaxy syndrome, abnormal spectrum of anomalies in the relations of the thoracoabdominal organs. It may be accompanied by right isomerism or left isomerism. Attempts to classify it into two subgroups are usually difficult since none of these has unique and pathognomonic findings, but rather there is broad overlap. Both are of poor prognosis, in the cases of left isomerism 5-10% reach adulthood, with a worse prognosis being the cases of right isomerism due to the fact that they have immunodepression secondary to asplenia and more severe congenital cardiopathies. Each case should be analyzed in an individualized and detailed manner to establish the diagnosis, determine the lesional association and establish those patients that present a higher risk of complications.
