“…Although craniopharyngioma is a relatively common tumor of childhood, $10% of intracranial neoplasms, it seldom occurs before birth. [48][49][50][51][52][53][54][55][56][57][58][59] Because of its epithelial morphology and location intimately related to the pituitary gland, it is thought to arise from Rathke's pouch, an ectodermal diverticulum developing from the roof of the mouth. 29,30 Craniopharyngioma was third in frequency following teratoma and astrocytoma in this review (Tables 1 and 5).…”

“…29,30 Craniopharyngioma was third in frequency following teratoma and astrocytoma in this review (Tables 1 and 5). Macrocephaly and a heterogeneous, calcified suprasellar mass were the main imaging findings; hydrocephalus and intrauterine death were next 48,50,53,57,58 (Table 5). Fetuses with large cranopharyngiomas generally have a poor outcome with few survivors.…”

The purpose of this literature review is to describe the various types of brain tumors that occur in the fetus, their locations, initial findings, pathology, and outcome. Data are presented that show which patients are likely to survive or benefit from treatment compared with those who are unlikely to respond. An analysis is performed on patients with fetal brain tumors that were detected prenatally by imaging studies or discovered directly after birth. The review revealed 154 fetuses presenting with brain tumors. Teratoma was the leading neoplasm. Next was astrocytoma followed by craniopharyngioma, primitive neuroectodermal tumor, choroid plexus papilloma, meningeal tumors, and ependymoma. The most common presenting findings were macrocephaly and an intracranial mass. Overall hydrocephalus was next, followed by stillbirth. Most tumors were detected during the third trimester of pregnancy. Over a third of the affected fetuses were stillborn. Many tumors were inoperable as they occupied much of the intracranial cavity and involved large areas of the brain. Overall survival rate was 23/154, or 15%. Generally fetal brain tumors are associated with a poor prognosis.

“…Since then, further pregnancies with congenital brain tumors have been documented; most commonly gliomas and teratomas [82] . Early detection of malignant cancers during the prenatal period is made possible by modern ultrasonography devices and routine ultrasonography screening during pregnancy, further assisting neurosurgeons in diagnosing and acting earlier on the progression of tumor growth [83] . Of note, teratomas make up around 62% of all brain tumors discovered during pregnancy, primarily during the second or third trimester [84] .…”

The Role of Advanced Imaging in Neurosurgical Diagnosis

Neurosurgery as a specialty has developed at a rapid pace as a result of the continual advancements in neuroimaging modalities. With more sophisticated imaging options available to the modern neurosurgeon, diagnoses become more accurate and at a faster rate, allowing for greater surgical planning and precision. Herein, the authors review the current heavily used imaging modalities within neurosurgery, weighing their strengths and weaknesses, and provide a look into new advances and imaging options within the field. Of the many imaging modalities currently available to the practicing neurosurgeon, magnetic resonance imaging (MRI), computed tomography, positron emission tomography, and ultrasonography are used most heavily within the field for appropriate diagnosis of neuropathologies in question. For each, their strengths are weighed regarding appropriate capabilities in accurate diagnosis of cranial or spinal lesions. Reasoning for choosing one over the other for various pathologies is also reviewed. Current limitations of each is also assessed, providing insight for possible improvement for each. New advancements in imaging options are subsequently reviewed for best uses within neurosurgery, including the new utilization of FIESTA sequencing, glymphatic mapping, black-blood MRI, and functional MRI. The specialty of neurosurgery will continue to heavily rely on improvements within imaging options available for improved diagnosis and greater surgical outcomes for the patients treated. The synthesis of techniques provided herein may provide meaningful guidance for neurosurgeons in effectively diagnosing neurological pathologies while also helping guide future efforts in neuroimaging developments.

“…This tumor may appear with a cystic component. 98 The predominant imaging findings were macrocephaly and a heterogeneous, suprasellar mass with calcification; hydrocephalus and intrauterine death followed 99,100 (Figure 8). Fetuses with big craniopharyngiomas have a terrible prognosis, with few surviving.…”

Ultrasound and magnetic resonance imaging features of fetal intracranial cystic lesions: A pictorial essay

This pictorial essay focuses on ultrasound (US) and magnetic resonance imaging (MRI) features of fetal intracranial cysts. Intracranial cysts are common findings in prenatal imaging, and if great attention is paid to their size, location, and imaging features, they can be diagnosed accurately. They are usually detected by fetal ultrasound exams. However, when ultrasound data on cystic lesion characteristics is insufficient, MRI and fetal neurosonogram are the best options for detecting other associated anomalies. The prognosis is highly dependent on their location and whether they are associated with other fetal anomalies.
