Follow-up in Head and neck cancer. What the Radiologist must know.
ute;zquez Olmos C Abstract The management of patients with head and neck cancer implies a multidisciplinary treatment with surgery, radiotherapy and chemotherapy. Imaging is crucial in their follow-up, especially when the tumor recurrence is not clinically evident. Radiologically distinguishing post-treatment changes from a tumor recurrence is a challenge due to the anatomical alteration due to surgical techniques and their reconstructions, radiotherapy treatment and chemotherapeutic guidelines. The differential diagnosis must include the possible complications derived from radiotherapy (mucosal necrosis, osteorad...

Aortic dissection class 3: a little-known entity. Presentation of 4 cases.
na GL Abstract Aortic dissection (AD) is the most common acute condition of the aorta and has a high mortality. Therefore, it is a radiological emergency of vital importance. Currently, five subtypes are distinguished, among which AD class 3 -also known as limited or subtle AD- is the less recognised. This type of dissection is infrequent and needs to be acknowledged radiologically in order not to go unnoticed. Regarding its imaging features, this entity is characterized by a small focal bulging of the aortic wall outline and/or a limited round dilation at the region affected by the intimal tear. Recently, the low...

Update in the evaluation of peripheral nerves by MRI, from morphological to functional neurography.
sse R Abstract Imaging studies of peripheral nerves have increased considerably in the last ten years. In addition to the classical and still valid study by ultrasound, new neurographic techniques developed from conventional morphological sequences (including 3D isotropic studies with fat suppression) are making it possible to assess different peripheral nerves and plexuses, including small sensory and/or motor branches, with great precision. Diffusion-weighted sequences and diffusion tensor imaging have opened a new horizon in neurographic studies. This new approach provides morphological and functional informati...

Intraductal papillary neoplasm of the bile duct: Radiologic findings in a new disease.
s Serrano B Abstract Intraductal papillary neoplasm of the biliary tract (B-IPN) is a scarcely known entity in our daily practice due to its low prevalence. Until its new definition in the fourth edition of the WHO classification of the digestive tract tumors of 2010 the disease was grouped under a heterogeneous and imprecise terminology. In addition, in recent years there has been progress in the knowledge of its etiopathogenesis, its natural history and its findings in image. The purpose of this paper is to review these data underlining the radiological findings of the disease and its differential diagnosis. ...

Ultrasonography of subcutaneous foreign bodies: differences depending on their nature, complications, and potential diagnostic errors.
M, Gallardo Agromayor E Abstract Patients with penetrating wounds with suspected foreign bodies retained in the wound are often seen in emergency departments. Imaging studies are necessary to rule out the presence of retained foreign bodies. Plain-film X-rays, however, are only useful when the foreign bodies contain radiopaque material (metal, glass, stone, and some plastics). In cases with strong diagnostic suspicion and negative plain films, other imaging tests are necessary. Ultrasonography has proven useful in the identification and location of both radiopaque and radiotransparent foreign bodies. Ultrasonograp...

Multidetector computed tomography (MDCT) is the imaging technique of choice in this scenario because it is widely available, fast, and useful for characterizing facial fractures and associated complications, including those located in the head. For all these reasons, MDCT is fundamental in the clinical management of these patients and in planning surgery. This paper describe...

Aortic root rupture and acquired intracardiac shunt after transcatheter aortic valve implantation.
Angulo Hervías E Abstract Transcatheter aortic valve implantation (TAVI) is an alternative to surgical valve replacement in patients with high surgical risk. Although TAVI is becoming more and more common, it is not without complications. Rupture of the aortic root after implantation is an uncommon, but lethal complication; few cases have been described in the literature. Multidetector computed tomography is fundamental before TAVI to evaluate factors that predispose to complications; however, its role after the procedure is still controversial.

Imaging findings for mucinous tumors of the abdomen and pelvis.
This article aims to describe the imaging findings for mucinous tumors of the abdomen and pelvis, which have a similar appearance on imaging tests regardless of the organ in which they develop. Due to the high water content of mucus, the appearance of these tumors is generally similar to that of water on ultrasonography, computed tomography, and magnetic resonance imaging. Another common feature of mucin-producing tumors is that calcifications are often present. The rupture of these lesions and accumulation of mucinous material in the peritoneal cavity gives rise to pseudomyxoma peritonei. It is important to identify mucin...

CONCLUSION: The incidence of sclerosing encapsulating peritonitis is low. The pathophysiology of this condition is unclear. Two types are recognized: idiopathic and secondary; the secondary type is generally a complication of peritoneal dialysis. Its nonspecific clinical presentation and the absence of blood markers mean that sclerosing encapsulating peritonitis is usually diagnosed late.

The anatomic details that magnetic resonance images provide are fundamental for diagnosing, characterizing, and staging both primary tumors and lymph node metastases. In addition to technical improvements in anatomic sequences, such as Dixon techniques to improve fat suppression, other sequences being developed, such as diffusion and perfusion, provide molecular, biological, and physiological information about the tumor and are yielding imaging biomarkers that can help in determining the tumor'...

Pulmonary histiocytosis: beyond Langerhans cells related to smoking.
CONCLUSION: Langerhans cell histiocytosis, Rosai-Dorfman disease, and Erdheim-Chester disease are idiopathic diseases in which the proliferation and infiltration of histiocytes is the histologic finding that confirms the diagnosis. Langerhans cell histiocytosis manifests as nodules and cysts that spare the costophrenic angles; it typically appears in smokers. Although it is uncommon in nonsmokers, Langerhans cell histiocytosis should also be considered in nonsmokers treated with chemotherapy and radiotherapy in whom cavitated nodules appear and should be included in the differential diagnosis together with metastatic disea...
