The clothes maketh the sign.

UNLABELLED: Pattern recognition is a key tool that enables radiologists to evoke certain diagnoses based on a radiologic appearance. In Shakespeare's Hamlet, Polonius tells his son Laertes to dress well because "apparel oft proclaims the man"; this phrase is now expressed in modern parlance as "the clothes maketh the man". Similarly in radiology, appearances are everything, and in the case of radiologic signs, occasionally "the clothes maketh the sign". The radiologic signs described in this pictorial review resemble items of clothing, fabric types, headwear, or accessories and are found in the musculoskeletal, pulmonary, gastrointestinal, and genitourinary systems. These "clothing signs" serve as a useful visual trigger to help radiologists to identify particular disease entities. TEACHING POINTS: • Pattern recognition enables radiologists to evoke a diagnosis based on radiologic appearance. • The radiologic signs described in this review resemble clothing, fabric, or accessories. • These "clothing signs" serve as visual triggers that evoke particular disease entities.

Stenting for infantile adult aortic coarctation with successful conception of zygomatic twins at 4 years' post-intervention.

INTRODUCTION: Aortic coarctation is a congenital defect which rarely presents in adulthood but results in significant morbidity and mortality. Endovascular techniques present novel therapeutic options for managing this anomaly with comparable results to traditional open surgical repair. PRESENTATION OF CASE: We convey a case of postductal aortic coarctation in a symptomatic 31-year-old woman, undetected, despite 27 years history of congenital bicuspid valve with aortic incompetence. We staged a successful endovascular repair following presentation with hypertension, abdominal pain, and worsening lower limb claudication. This lady recovered well, eventually giving birth to twins after a successful caesarean section delivery. The anatomical, clinical and technical features of the case are appraised. DISCUSSION: Aortic coarctation is classified anatomically as preductal (infantile) or postductal (adult) and the morphological spectrum of abnormality ranges from a discrete stenosis distal to the left subclavian to a hypoplastic transverse arch and aortic isthmus presenting in infancy. Its incidence is 0.2-0.6 per 100 live births. Traditional open surgical repair of aortic coarctation is associated with high morbidity and mortality. Advances in endovascular techniques with their associated shorter hospital time and lower costs, reduced short term morbidity and mortality mean that they are likely to become mainstays of treatment. CONCLUSION: The presentation of aortic coarctation for the first time in an adult is extremely unusual. Error and delayed diagnosis can never be fully exempted in the practice of medicine even with the most advanced diagnostic tools. Follow-up is mandatory by trans-oesophageal echo in all endovascular patients.

Primary malignant gastric PEComa - Diagnostic and technical dilemmas.

INTRODUCTION: The World Health Organisation defines PEComa's as "a mesenchymal tumour composed of histologically and immunohistochemically distinctive perivascular cells".(1) These ubiquitous tumours show distinctive perivascular epithelioid cell differentiation and arise most commonly at visceral and abdominopelvic sites. PRESENTATION OF CASE: We present a case of a forty-two year old man presenting to accident and emergency department with upper gastro-intestinal bleeding. He had a palpable epigatric mass on examination. He underwent a CT Scan Abdomen which displayed a tumour arising from the gastric wall. Upper GI endoscopy and biopsy was carried out and biopsied were taken for histological analysis. A primary gastric PEComa was diagnosed and the patient underwent distal polya gastrectomy and gastrojejunostomy. This is believed to be the first reported case of a Primary malignant gastric PEComa. DISCUSSION: Perivascular epithelioid carcinomas were first described in 1943 as an abnormal myoblast in a case of renal angiomyolipoma. PEComas display a strong female predominance with a typical benign course. There are approximately 100 reported cases of PEComa to date, with 55 of which were malignant. PEComa's may be subdivided into benign, uncertain malignant potential and malignant. Their natural history can be very aggressive leading to multiple metastases and death as expected with a high-grade sarcoma. CONCLUSION: This case depicts the aggressive nature of malignant gastric PEComa's. The majority of PEComa's are benign in nature and have a better prognosis. We display here the challenges in ascertaining a definitive diagnosis and management of such patients due to limited clinical studies.
