ABSTRACT
Intra-orbital hydatid cyst is a very rare pathological entity that affects children and the young adults; it is secondary to the development in the orbit of the echinococcus granulosis tapeworm. Its frequency does not exceed 1% of all cases of hydatid disease. Clinical presentation of intra-orbital hydatid cyst is dominated by proptosis and a decrease in visual acuity, complete surgical excision is difficult, evolution is generally better when the treatment is early before the installation of irreversible optic atrophy. We report one case of a 3 years old girl operated for right intra-orbital hydatid cyst who presented with proptosis and blindness. Complete removal was difficult and puncture of the cyst was performed followed by excision of its membrane with good post-operative results. We also discuss the different epidemiological, clinical, radiological and therapeutic aspects of intra-orbital hydatid cyst and a review of literature of this rare pathology.

Nasofrontal fistulas correspond to the persistence of an abnormal communication of embryological origin between the deep layer of the skin and the central nervous system (CNS). They can rarely be associated with a dermoid cyst and be revealed by a locoregional infection, and especially neuromeningeal infections can be serious. The treatment is mainly surgical by performing a total excision of the cyst and the repair of defects. The authors report the case of an 18-month-old infant operated for a dermoid cyst revealed by a nasofrontal fistula. They insist on the characteristics of this pathology in order to establish a diagnosis and an early treatment to avoid the complications that can be heavy in certain cases. They describe the steps of nasofrontal reconstruction by a small flap taken from the outer table of the frontal bone with better esthetic results.
