Abstract Intradiploic arachnoid cysts have scarcely been reported in the literature, most reported cases being secondary to trauma. Nontraumatic arachnoid cysts are quite rare and have been reported mostly in adults. Here, we report the case of a 16-year-old male presenting with a slowly growing mass in the occipital region and intermittent headaches. On the basis of the findings of X-rays, computed tomography scans, and magnetic resonance imaging scans of the head, the mass was diagnosed as a giant intradiploic arachnoid cyst.

Resumo Cistos aracnóideos intradiploicos foram raramente relatados na literatura, sendo a maior parte desses casos decorrente de traumas. Cistos aracnóideos não traumáticos são muito raros e têm sido relatados principalmente em adultos. Aqui, relatamos o caso de um jovem de 16 anos de idade apresentando uma massa de crescimento lento na região occipital e dores de cabeça intermitentes. Com base nos resultados de radiografia, tomografia computadorizada e ressonância magnética da cabeça, a massa foi diagnosticada como um cisto aracnóideo intradiploico gigante.

Double gallbladder is rare congenital anomaly. It is important to diagnose it preoperatively. Ultrasound is the preferred modality of imaging. Laparoscopic cholecystectomy can be safely done in benign condition of double gallbladder. This anomaly is important to know for surgeons because of associated anatomical variations of main bile duct and hepatic artery and increased risk of common bile duct injury.

Bilateral hip dislocation occurring as a result of trauma is a rare condition. Simultaneous anterior and posterior traumatic dislocation of both hips is even more unusual. A case is reported of bilateral asymmetrical traumatic hip dislocation in previously normal hips in a 20 year old adult male without an associated fracture of the pelvis or femur. An unusual mechanism for this injury is also described.
