The Caecum is the commencement of the large intestine. It is the large cul-de-sac which lies in the right iliac fossa and continues with the ascending colon at the level of the ileal opening.[Gray__ampersandsignrsquo;s Anatomy 2000] Normally caecum lies in on the peritoneal floor of the right iliac fossa and its lower end lies at the pelvic brim [Sinnatamby CS 1999]. The shape of caecum has been classified into four types, ie, conical 2%, quadrate 3%, 90% normal and ampullary 4% by Treves. During routine cadaveric dissection by I MBBS students at BMCRI Bangalore, a variation is seen in a 60 year old female cadaver. The caecum is conical in shape and found in the right lumbar region. Length of the caecum is 5 cm and breadth 5.25 cm. The appendix is retrocaecal and its length 6 cm. This variant shape and position of the caecum can be explained on an embryological basis. The congenital anomaly of undescended caecum gives rise to confusion in diagnosis of appendicitis. The Mc Burneys point used for locating the tenderness of appendicitis totally depends on the normal position of the base of appendix. Despite extraordinary advances in modern radiographic imaging, diagnosis of acute appendicitis remains an enigmatic challenge. A knowledge of variable positions of caecum and appendix will help in diagnosing cases of appendicitis with atypical presentations and in planning proper incisional techniques preoperatively.
