Case presentation We report a case of rare pure cystic heterotopic brain tissue in a two-month-old Caucasian baby girl that presented as a large cystic neck mass and was confused with a cystic hygroma. Her mother reported a progressive increase in the size of this swelling and mild respiratory difficulty when the girl was sleeping. A computed tomography scan of the brain and neck showed a large heterogeneous mass extending from the base of the skull to the left submandibular region a cystic component was also noted. Our patient under went total excision of the cystic mass and prevention of airway obstruction by a left submandibular approach. The final gross pathology diagnosis was heterotopic brain tissue. Conclusions Pure cystic neck heterotopic brain tissue lesions are very uncommon and a preoperative diagnosis of this lesion is difficult. Brain heterotopia is a rare benign condition that should be considered in the differential diagnosis of the neonatal head and neck mass. Introduction Neuroglial heterotopia heterotopic brain tissue or differentiated neural tissue outside the cranial vault is uncommon and these anomalies most commonly occur in the nasal cavity 1 2 . In rare instances neuroglial heterotopia in the neck has been reported 3-5 . Previous reports of these cases have shown only computed tomography CT images of neuroglial heterotopia presenting as a low-attenuation mass with some area of focal cystic formation 3-6 . The most common location of heterotopic brain tissue is .
