Gallbladder agenesis is a rare entity with an estimated incidence of 10-65 per 100,000. Females are more commonly affected (ratio 3:1), typically presenting in the 2nd or 3rd decade of life. Despite an absent gallbladder, half of patients present with symptoms similar to biliary colic, which is poorly understood. Clinicians should have a strong index of suspicion if nonvisualization is suggeste...

OBJECTIVE The objectives are to analyse corpus callosum agenesis in children with various neurological problems in a hospital set-up, and to study the neurological and systemic abnormalities associated with this condition. METHODS The children with various neurological problems who underwent computerized tomography brain from January 1993 to December 1997, and were found to have corpus callos...

Thyroid gland is the largest of all endocrine glands. It is composed of two lobes. These two lobes are joined by an isthmus and this resemble the letter "H". A wide range of morphological variations and developmental anomalies of the thyroid gland like hypoplasia, ectopy, hemiagenesis, and agenesis have been reported in literature. Out of these, the incidence of agenesis of the thyroid isthmus ...

Pulmonary agenesis, a rare congenital condition, is incompatible with life when present bilateral, while unilateral agenesis is usually detected in infancy or early childhood. Rare asymptomatic patients may reach adulthood undiagnosed, with signs mimicking common conditions presenting as radiopaque hemithorax with ipsilateral mediastinal shift. Here, we describe a case of a young lady, with his...

COMPLETE or partial agenesis of the corpus callosum is uncommon especially in adults; the incidence amongst patients in institutions where numerous air encephalograms are performed is 3% (Carpenter and Drukemiller, 1953). Reil (1812) published the first report of a case, describing the necropsy findings in a 30 year old woman of low mentality; further cases discovered at necropsy were subsequen...

Tracheal agenesis is an extremely rare and typically lethal congenital disorder. Approximately 150 cases have been described since 1900, and very few cases of survival have been reported. We describe tracheal reconstruction with external esophageal stenting in a patient with Floyd's type II tracheal agenesis. Neither long-term survival nor survival without mechanical ventilation for even a sing...

Bilateral femoral agenesis is a rare anomaly. To the best of our knowledge, only three cases of simple congenital anomaly and three cases associated with femoral facial syndrome have been reported. Here, we describe a simple form of bilateral femoral agenesis observed in one of the 2 dead fetuses delivered after termination of a 24-week twin pregnancy of a normal mother. Post-mortem x-ray exami...

The agenesis of the corpus callosum results from a failure in the development of the largest fiber bundle that connects cerebral hemispheres. Patient's outcome is influenced by etiology and associated central nervous system malformations. We describe a child with Turner syndrome (TS) mosaicism, with particular phenotype features and a complete agenesis of the corpus callosum. To our knowledge, ...

Caudal regression syndrome is a rare congenital anomaly with characteristic agenesis or dysgenesis of caudal vertebrae varying from isolated partial agenesis of coccyx or entire lumbosacral vertebrae.1,2 It may be associated with congenital anomaly of spinal cord, genitourinary tract, and gastrointestinal tract.3–5 The children with extensive bony defects in caudal regression syndrome may prese...

Mullerian duct abnormalities are congenital malformations that are easily missed and can lead to incorrect diagnosis and unnecessary operative procedures. In this case, a young female presented with cyclic pelvic pain that continued after previous surgical resection of an ovarian cyst. Further investigation with clinical examinations and multimodality imaging demonstrated ipsilateral renal agen...
