Idiopathic intracranial hypertension presenting as bilateral spontaneous lateral intrasphenoidal and transethmoidal meningoceles: a case report and review of the literature

Abstract

Background Basal meningoceles are rare herniations of the meninges that tend to present unilaterally with cerebrospinal fluid rhinorrhea. Growing evidence suggests that intracranial hypertension contributes considerably to the formation of spontaneous basal meningoceles. Case presentation A 50-year-old man of Middle East ethnicity presented with a 16-week history of cerebrospinal fluid rhinorrhea, short-term memory loss, and slight decline in cognitive function. We present a case of bilateral spontaneous meningoceles with bone defects in the left lateral sphenoid sinus and right anterior cribriform plate, as well as with a remodeled sella. A neuronavigation-assisted expanded endoscopic endonasal surgery was performed to resect the meningoceles. Postoperative imaging demonstrated complete resolution of the bilateral meningoceles. Conclusions This case reports the first bilateral basal spontaneous meningoceles in the literature. Furthermore, based on this case’s imaging results and the literature reviewed, elevated intracranial pressure may be a determining factor behind the development of spontaneous meningoceles.

Occipital encephalocele at a tertiary care hospital

“…Occipital encephalocele is often associated with craniofacial anomalies or other brain malformations such as hydrocephalus, paralysis of the upper and lower limbs, microcephaly, ataxias, retarded child development, visual disturbances, mental and growth retardation, and seizures (7). For the symptomatology of encephalocele, one encounters the symptoms that are visible like seizures and disturbances of cognition, including intellectual and developmental de cits and a disproportion of the size of the head compared to the body (8).…”

Association of neural tube defects with congenital abnormalities of the urogenital system in a Chinese cohort

“…Furthermore, although renal dysplasia is often asymptomatic, hypertension can be caused by vascular malformation [13]. in the process of embryonic development, the skeletal muscle system was also homologous with the urogenital system that originated from the mesoderm, and the development time is also in the early embryo [14][15][16][17][18].…”

A Rare Case of Asymptomatic Bilateral Naso-Orbital Meningoencephalocele

“…Подобные патологии редки: частота их встречаемости, по данным литературы, составляет в среднем 4 случая на 10 тыс. больных [2][3][4][5][6][7][8][9][10][11][12]. Согласно другим источникам менингоцеле и МЭЦ встречается значительно реже, с частотой 1 случай на 12,5 тыс.…”

“…МЭЦ -преимущественно единичное образование, множественные МЭЦ у одного пациента встречаются крайне редко [11,12,[22][23][24][25][26][27]. Известен один случай с тремя идиопатическими МЭЦ у одного больного [27].…”
