Abstract:Thyroid hemiagenesis is a rare congenital anomaly in which one lobe of thyroid fails to develop; which may or may not be associated with failure of development of the isthmus. Most of the patients remain asymptomatic. Thyroid pathologies are more common in these patients than the normal population. Euthyroid cases without any above mentioned disorders need reassurance for the patient. Importance of this case lies in two important things. First thyroid hemiagenesis is associated with increased incidence of other associated disorders including malignancy. Hence close follow up is essential. Secondly, when in euthyroid status, proper patient counselling and avoidance of unnecessary surgery are of paramount importance to avoid permanent hypothyroidism.

Meckel's diverticulum is the commonest congenital malformation of the gastrointestinal tract. 2 Although it mostly remains silent, it can present with pain abdomen, bleeding, perforation, intestinal obstruction, intussusception, and malignant transformation. 3 Stone formation in Meckel's diverticulum is rare 1 and to identify this pre-operatively is extremely difficult. Meckel's stones may be misinterpreted as gallstones, teeth within a dermoid or an appendicealfaecolith when symptomatic. The pathogenesis of lithiasis in Meckel's diverticulum remains unclear. It may be related to stasis resulting from poor coordination of peristaltic waves at the site of Meckel's diverticulum. 1,2 The absence of ectopic gastric mucosa may also lead to a more alkaline environment in the diverticulum, favouring precipitation of calcium and other minerals necessary for lithiasis. 4,5 The "stone" itself may usually be either a fecolith, bezoar, or gallstone. Meckel's diverticulumlithiasis can cause acute or intermittent abdominal pain, chronic gastrointestinal blood loss, diverticulitis, perforation 1 or sub-acute intestinal obstruction. This case report illustrates one of the few circumstances when a plain abdominal X-ray may provide a helpful clue to the diagnosis of Meckel's diverticulum.
