This paper reports the results of two exploratory studies (overall N=532) which aimed at drawing the profile of the “sustainable tourist” (a person committed to respect the sustainability principles when on holiday) in terms of personal values, attitudes, and personality traits, following an environmental psychology approach. More specifically, study 1 explored the role of attitudes toward sustainable tourism, affinity toward (social and environmental) diversity, and personal values, while study 2 assessed the role of the Big Five personality traits in the prediction of preferences for sustainable and unsustainable tourist activities. Results indicate that biospheric values, positive attitudes toward sustainable tourism, and higher levels of affinity toward diversity are able to predict more sustainable tourism choices while personality traits seemed to play a more indirect and complex role.

Retroperitoneal ganglioneuroma is a rare neuroectodermal tumor with a benign nature. We performed a literature review among 338 studies. We included 9 studies, whose patients underwent CT and/or MRI to characterize a retroperitoneal mass, which was confirmed to be a ganglioneuroma by histologic exam. The most common features of ganglioneuroma are considered to be a solid nature, oval/lobulated shape, and regular margins. The ganglioneuroma shows a progressive late enhancement on CT. On MRI it appears as a hypointense mass in T1W images and with a heterogeneous high-intensity in T2W. The MRI-“whorled sign” is described in the reviewed studies in about 80% of patients. The MRI characterization of a primitive retroperitoneal cystic mass should not exclude a cystic evolution from solid masses, and in the case of paravertebral location, the differential diagnosis algorithm should include the hypothesis of ganglioneuroma. In our case, the MRI features could have oriented towards a neurogenic nature, however, the predominantly cystic-fluid aspect and the considerable longitudinal non-invasive extension between retroperitoneal structures, misled us to a lymphatic malformation. In the literature, it is reported that the cystic presentation can be due to a degeneration of a well-known solid form while maintaining a benign character: the distinguishing malignity character is the revelation of immature cells on histological examination.
