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.

Abstract:Amniotic band syndrome is a rare set of congenital malformations attributed to the anomalous amniotic bands that entangle fetal parts during intrauterine life resulting in a broad spectrum of anatomical disturbances. It is a rare condition and is mostly associated with other musculo-skeletal disorders. Amniotic band syndrome should be considered in every newborn with congenital anomalies, especially defects of extremities and/ or body walls. We report a case of amniotic band syndrome along with X ray findings in a male child born with congenital malformation of the extremities.

Macrodystrophia lipomatosa is a rare entity that is mostly diagnosed in children. It has been very rarely reported in adults. Here, we describe the X-ray and computed tomography findings in a case of macrodystrophia lipomatosa in an elderly female presenting with an enlarged second toe since birth and bony outgrowths causing pressure effects and cosmetic problems.
