“…Typically US shows a distended fluid filled appendix, with variable internal echogenicity depending on the internal content and consistency (aqueous or gelatinous), which may be anechoic, hypoechoic or heterogeneous (onion skin sign) [123][124][125][126] (fig 12). The onion skin sign defined as echogenic layers or a layered appearance of the internal contents of the mass have been described as specific of AM [124].…”

Transabdominal gastrointestinal ultrasound (GIUS) is unique in its capacity to examine the bowel non-invasively and in its physiological condition, including extra-intestinal features such as the splanchnic vessels, mesentery, omentum and lymph nodes- even at the bedside. Despite this, and its extensive documentation for its usefulness, it has only been fully implemented in a few European countries and expert centres. Therefore, the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) established a GIUS Task Force Group in 2014 consisting of international experts from 9 European countries with the objectives to standardize and promote the use of GIUS in a clinical setting. This is achieved by publishing clinical guidelines and recommendations on indications and use of GIUS and so far,4 guidelines have been published: first on “examination techniques and normal findings”, second on “inflammatory bowel disease”, third on “acute appendicitis and diverticulitis” and fourth on “transrectal and perineal ultrasound”.This paper describes the ultrasound features of miscellaneous disorders such as celiac disease, cystic fibrosis, omental infarction, Meckel’s diverticle, endometriosis, intestinal neoplasia, mucocele, amyloidosis, GVHD, foreign bodies, vasculitis, and pneumatosis cystoides intestinalis. Bowel ultrasound can be indicated in most of these conditions to investigate intestinal symptoms but in other cases the alterations of the bowel can be also an incidental finding that suggest other examinations which finally help to discover an unknown pathological condition.

“…The presence of curvilinear or punctate non-luminal calcification strongly supports a diagnosis of AM. Wall irregularity and nodular contrast-enhancing lesions of the mucocele may suggest malignancy [125]. The presence of ascites and peritoneal thickening suggests the intraperitoneal spread of neoplastic cells.…”

“…La falta de engrosamiento de la pared es un hallazgo que permite diferenciar entre una apendicitis aguda no complicada y un mucocele; el grosor es menor de 6 mm en el mucocele y, mayor de 6 mm, en la apendicitis aguda. En el enema con bario, la existencia de pliegues cecales de morfología espiral, o bien un defecto de repleción apendicular, son hallazgos indicativos de mucocele apendicular [6][7][8][9] .…”

“…En ocasiones, se puede observar calcificaciones parietales puntiformes o curvilíneas. La existencia de ascitis o de masas de densidad de tejido blando que comprimen las vísceras abdominales, sin infiltrarlas, sugiere un pseudomixoma peritoneal [6][7][8][9] .…”

Los tumores mucosos apendiculares tienen baja incidencia y comúnmente se diagnostican en el estudio anatomo-patólogico después de la apendicectomía. Se reporta el caso de una mujer de 41 años de edad, con un cuadro clínico de ocho meses de evolución, caracterizado por dolor abdominal de tipo opresivo, difuso y de gran intensidad en el hemiabdomen inferior, acompañado de náuseas. Después de cinco meses de iniciado este cuadro clínico, se evidenció una masa en la fosa iliaca derecha; el dolor se agudizó e intensificó, y las náuseas continuaron, por lo cual fue remitida al hospital. En los exámenes practicados se observó una masa quística compleja abdomino-pélvica de origen indeterminado, y la tomografía computadorizada de abdomen fue sugestiva de mucocele apendicular. Con estos hallazgos, se optó por el tratamiento quirúrgico por laparotomía, consistente en hemicolectomía derecha, con resección parcial de íleon, epiplectomía, histerectomía y salpigooforectomía bilateral
