The iniencephaly involves a variable defect in the occipital bone, resulting in a large foramen magnum, partial or total absence of the cervical and thoracic vertebrae, accompanied by incomplete closure of arcs and/or vertebral bodies, significant shortening of the spinal column and hyperextension of the malformed cervicothoracic spine; the individual's face is deviated upward, the mandibular skin is directly continuous with anterior thorax due to the absence of neck. Its incidence is about 1:1000-1:2000 births, so this is a pretty rare neural tube defect. We present a case of iniencephaly in association with cardiovascular, spinal cord, and intracranial malformations that ended demonstrating the low survival of patients affected with this condition.

Iniencephaly is a rare malformation of the base of the cranium, with an almost always fatal prognosis. This condition is part of the category of defects related to neural tube closure. Prenatal diagnosis can now be performed through ultrasound evaluation, allowing timely counseling.

Postoperative pseudomeningocele is a rare, but still existing, complication after spinal surgeries. It may be asymptomatic or presented with back pain, radicular pain or headaches. Many pseudomeningoceles resolve spontaneously, others require revision surgery with dural repair.

Background: Neural tube defects (NTDs) are defined as an incomplete closure of the neural tube (NT), with a prevalence of 1.2 per 1000 live births around the world. Methylation of the maternally imprinted gene Insulin-like growth factor 2 (IGF2) is one of the epigenetic mechanisms that contribute significantly to the development of NTDs.

Iniencephaly is an extremely rare type of neural tube defect characterized by the fusion of the cervical and cervicothoracic vertebrae. This condition results in acute retroflexion of the head, a short neck, significant lordosis of the cervical spine, and an upturned facial appearance. This condition typically results in poor fetal outcomes, with many cases ending in stillbirth or neonatal death.

Background: Giant prolactinoma (size > 4 cm) is a rare condition and accounts for less than 1% of pituitary adenomas. In even rarer cases, these lesions may involve craniocervical structures requiring surgical intervention. The present case is the largest reported giant prolactinoma (99 × 72 × 57 mm).
