Meckel's diverticulum is the most prevalent congenital abnormality of the gastrointestinal tract. This anomaly is due to the incomplete obliteration of the omphalomesenteric duct during the 7th week of gestation and is classically located 2 feet proximal to the ileocecal valve. Variations of this congenital malformation have been recorded based on location, size, and form. While most of the population may be asymptomatic, clinical manifestation, including gastrointestinal bleed and intestinal obstruction, can emerge. Despite the frequency of Meckel's diverticulum, it is commonly misdiagnosed due to its mimicry of appendicitis. This article aimed to review this derailment of embryological development.

medical training. In this respect, the West has something to learn from Thailand. We thank Sanjai Sangvichien, Bangkok, for background information; Wiphawi Hipkaeo, Phitsanulok, for support and many helpful comments; and the Thai teachers and students who received us with such great friendliness. We also thank Ronald Frankenberg for supervision of AW's fieldwork and Kimberly Rosegger for help with the manuscript. Contributors and sources: Both authors have a German medical background and currently teach anatomy to medical students. This paper arose from AW's MSc dissertation in medical anthropology (Brunel University), during which he conducted two months of anthropological fieldwork (participant observation in the dissecting room and informal interviews with faculty members and students) in Phitsanulok. FHG spent over three years working as an anatomist in Thailand. AW is the guarantor. Competing interests: None declared. 1 Furness P. Consent to using human tissue.

Practitioners who care for women after HD therapy need to educate patients regarding their risks and begin early screening. Screening by mammography can detect small, node-negative breast cancers in these patients.

Anomalies in the course and drainage of the Inferior Vena Cava (IVC) may complicate normal functioning, correct diagnosis, and therapeutic interventions within the abdomen. Development of the IVC occurs during the 4th to 8th week of gestation, and due to its developmental complexity, there are many opportunities for malformations to occur. Although most IVC anomalies are clinically silent and are usually discovered incidentally on abdominal imaging, aberrations may be responsible for formation of thrombosis, back pain, and anomalous circulation of blood to the heart. In this review, we will discuss the most common variations and abnormalities of the IVC, which include the posterior cardinal veins, the subcardinal veins, the supracardinal veins, persistent left IVC, IVC duplication, situs inversus, left retroaortic renal vein, left circumaortic renal collar, scimitar syndrome, and IVC agenesis. For each abnormality outlined above, we aim to discuss relevant embryology and potential clinical significance with regards to presentation, diagnosis, and treatment as is important for radiologists, surgeons, and clinicians in current clinical practice.
