Endoscopic Treatment of In Utero Diagnosed Multiloculated Inter Hemispheric Cyst in a Newborn: Case Report
Interhemispheric cysts, often associated with agenesis of corpus callosum, are rare lesions. The optimal treatment is still controversial. Placement of cystoperitoneal shunt and open microsurgery are traditional treatments. Neuroendoscopy in children is due to its minimal invasiveness a new emerging option. There have been a few published cases on neuroendoscopic treatment of interhemispheric cyst in children. The authors document the youngest reported child with multiloculated interhemispheric cyst that was treated with neuroendoscopy. The cyst was detected in a male fetus in 35th week of gestation and in utero magnetic resonance imaging was performed in 37th week of gestation. After delivery, progressive macrocrania with signs of raised intracranial pressure developed. Endoscopic cystoventriculocisternostomy was performed 28 days after the birth. There was a marked symptom relief. One month after the surgery, magnetic resonance showed shrinkage of the cyst and expansion of the brain parenchyma. After a 2-month follow up period, the child showed normal neurologic development and head circumference increased by only 0.5 cm. The created fenestrations enabled the brain to expand. Neuroendoscopic treatment of interhemispheric cysts should be considered the operative technique of choice in newborns. Although the intracranial pressure and the size of the cyst have decreased, long-term follow up is necessary and future studies on more cases are needed.
