116C ongenital cystic eye, known also as anophthalmos with cyst, is an extremely rare congenital anomaly, first described by Mann in 1939 (1). Pathogenetically, it results from an arrest in the invagination of the primary optic vesicle between the 2-mm and 7-mm stages of fetal development (2-5). Herein we present the findings of radiography, ultrasonography (US), and magnetic resonance imaging (MRI) in a unique case of congenital cystic eye associated with dermal appendages and intracranial congenital anomalies in a 3-month-old boy.
Case reportA 3-month-old boy presented to our department for investigation of a large mass in the left orbital region, which had been present since birth. The boy was well developed and was otherwise in good health. Results of screening hematology and blood biochemistry tests were within normal limits. In addition to the lesion extruding from the left orbit, a few dermal appendages of the left half of the face were also noted (Fig. 1).The boy was delivered by caesarian section in the 38th week of pregnancy (because of maternal history of previous caesarian section), with a birth weight of 2800 g. There were no complications during pregnancy or delivery. The parents were healthy and unrelated, with no history of illness or drug ingestion during pregnancy. No family history of developmental abnormalities was mentioned by the parents, who also had a healthy 2-year-old boy. Ultrasonography during pregnancy was not performed, so the lesion was unanticipated at birth.Physical examination demonstrated a large mass protruding from the left orbit. Both eyelids were stretched, covering the lesion. The lower eyelid was reddish and hyperemic. The mass was soft, non-tender, nonpulsatile, and cystic in consistency; the size did not change during crying. Ophthalmological evaluation of the right eye did not demonstrate any pathological findings. Systemic evaluation (except for the brain) did not reveal other abnormalities, including congenital heart disease.Radiographs of the skull revealed a soft tissue mass of the left orbit with expansion and remodeling of the superior and lateral bony walls of the orbit (Fig. 2). No abnormalities of the chest or abdomen were noted on radiographs.US of the left orbit demonstrated a mainly cystic lesion with a maximum diameter of about 6 cm. Within the cyst, there were a few septa; there was also a solid component with a diameter of about 2.5 cm with internal small cystic areas, and arterial and venous flow signals. No eye globe was identified in the left orbit (Fig. 3). There were no US abnormalities in the abdomen.MRI of the orbits and the head demonstrated the lesion as well as abnormalities of the brain. The lesion was mainly cystic, with internal septa and a solid intracystic component which contained smaller cystic areas, ABSTRACT Congenital cystic eye (anophthalmia with cyst) is an extremely rare anomaly discovered at birth with few reported cases in the literature, resulting from partial or complete failure during invagination of the primary optic vesicle...
