Epiploic appendagitis is a relatively rare disease characterized by an inflammation of fat-filled serosal outpouchings of the large intestine, called epiploic appendices. Diagnosis of epiploic appendagitis is made challenging by the lack of pathognomonic clinical features and should therefore be considered as a potential diagnosis by exclusion first of all with appendicitis or diverticulitis which are the most important causes of lower abdominal pain. Currently, with the increasing use of ultrasound and computed tomography in the evaluation of acute abdominal pain, epiploic appendagitis can be diagnosed by characteristic diagnostic imaging features. We present a case of epiploic appendagitis with objective of increasing knowledge of this disease and its diagnostic imaging findings, in order to reduce harmful and unnecessary surgical interventions.
Langerhans cell histiocytosis (LCH) is a rare disease of the myeloid precursor cells, it predominantly occurs in the skull and long bones as unifocal bone lesions. Aneurysmal bone cysts (ABC) are benign, expansive and lytic bone. Reports of secondary ABC occurring in LCH are rare, having only been reported twice in the skull. Here, we report the first case of LCH masquerading as ABC in a 14-month-old female child who presented with a rapidly growing mass in her left femur. The lesion had typical radiological features of ABC, and only histological examination revealed the presence of cells suggestive of LCH.
Purpose: Acute epiploic appendagitis (EA) is a relatively rare, benign and local inflammatory disease involving the epiploic appendices. Unlike its mimics, EA is generally a self-limiting inflammatory disease and can be treated conservatively. Case presentation: A 33-year-old Caucasian man presented to our emergency department with a sever and sharp left iliac fossa pain. He underwent abdominal X-ray, ultrasound (US) and computed tomography (CT) evaluations. Conclusion: We illustrate US and CT findings to increase the radiologists' awareness of this condition and to avoid diagnostic delay and unnecessary use of antibiotics, hospitalization and surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
