A Case of Corpus Callosum Agenesis with Ileal Atresia and Duplication

Agenesis of corpus callosum occurs sporadically and may be transmitted as sex-linked, or autosomal-dominant or recessive traits. It has been associated with different syndromes. Clinical pictures vary from severe intellectual and neurologic abnormalities to asymptomatic and normaly intelligent cases. Agenesis of corpus callosum may occur alone, but it is more frequently associated with a high incidence of other anomalies. We report a male infant with agenesis of corpus callosum who was diagnosed to have ileal atresia and duplication.

A Case of Primary Hypomagnesemia

Primary hypomagnesemia is a rare inherited disorder and it is considered to be due to either a defect in the intestinal transport of magnesium or a defect in renal tubular transport. It is important to measure the urinary excretion of magnesium to differentiate the causes of magnesium deficiency. We report here an one-month-old female infant of primary hypomagnesemia who presented generalized tonic-clonic seizures. She had hypomagnesemia(<1.5mg/dL) and several seizure attacks but normal magnesium creatinine ratio in random urine and normal magnesium excretion in 24-hour urine. Continuous oral magnesium supplementation was necessary to avoid the recurrence of symptoms and maintain serum rnagnesium levels.

Gallbladder Agenesis / 한국간담췌외과학회지

Gallbladder agenesis is a rare condition of hepatobiliary congenital anomaly. It is caused by failure of development of the caudal division of the primitive hepatic diverticulum or failure of vacuolization after the solid phase of embryonic development. It is divided into 2 groups: (1) those whose conditions are discovered clinically because of persistent symptoms and proven by abdominal exploration with operative cholangiography; and (2) those who are asymptomatic during life and whose conditions are discovered only at necropsy. If symptoms are present, they are unlikely to be related to gallbladder disease. It is impossible, at present, to make a preoperative diagnosis of gallbladder agenesis. Operative cholangiography is absolutely necessary to rule out an intrahepatic gall bladder. Confirmation at surgery and autopsy requires thorough dissection of the biliary tract and liver bed. Therefore, we presented this case with a brief review of the related literature.
