Small bowel angioedema. An unusual condition with an interesting differential diagnosis.

We present the case of a 35-year-old woman with a prior history of hereditary angioedema (HA) who was admitted to the emergency department with epigastric pain, vomiting and sweating. Laboratory tests showed raised APR levels (CRP and leukocytosis).

Fatal case of simply influenza A (H3N2)-associated encephalitis in immunocompetent patient.

Influenza virus-associated encephalopathy/encephalitis is a rare entity in adults that can lead to severe neurological sequelae and even death. The clinical presentation can be quite diverse. This absence of a typical presentation along with the difficulty detecting the virus in the cerebrospinal fluid represents a diagnostic challenge.

Gossypiboma Following Emergency Nephrectomy for Wunderlich Syndrome.

We describe the imaging findings of a case of an intra-abdominal gossypiboma (retained surgical sponge) in an asymptomatic 61-year-old man who underwent an emergency nephrectomy because of a Wunderlich syndrome secondary to a renal cell carcinoma. A follow-up computed tomography was performed 4 months after the emergency surgery and showed an extraperitoneal lesion with gas bubbles and radiopaque markings in the left hemiabdomen, consistent with a retained surgical sponge ("gossypiboma" or "textiloma") in the anterior pararenal space. The patient underwent scheduled surgery for extraction of the textiloma.

Preoperative Embolization of a Posterior Mediastinal Lipid-Poor Angiolipoma Mimicking a Paravertebral Nerve Sheath Tumor.

Mediastinal angiolipomas are extremely rare tumors within the thorax, and only 6 cases have been previously reported in the literature. We describe the case of a lipid-poor angiolipoma within the posterior mediastinum of a 63-year-old man who complained of chest pain. Interestingly, initial imaging of the posterior mediastinal mass of our patient suggested a nerve sheath tumor.

[PET/CT: protocol aspects and legal controversies].

The combination of positron emission tomography (PET) and computed tomography (CT) in a single scanner (PET/CT) allows anatomic and metabolic images to be fused and correlated with a high degree of accuracy; this represents a very important landmark in the history of medicine and especially in the area of diagnostic imaging. Nevertheless, the implementation, startup, and operation of a PET/CT scanner presents particularly interesting challenges, because it involves the integration of two well-established and consolidated techniques (CT and PET, which provide complementary information) that have traditionally been carried out in the context of two different specialties (radiology and nuclear medicine). The rapid diffusion of this new integrated technology raises a series of questions related to the optimal protocols for image acquisition, the supervision of the examinations, image interpretation, and reporting, as well as questions related to the legal competence and responsibility of the specialists involved in a PET/CT study.
