Alveolar echinococcosis (AE) is an important parasitic infestation caused by the larval stage of the Echinococcus multilocularis. Turkey is one of the countries occurred endemic of the disease. The disease primarily affects the liver. Cerebral and craniofacial involvements are very rare. Here the authors report a 46-year-old woman with simultaneous cerebral and craniofacial involvement of E. multilocularis. Although primary AE lesions with simultaneous cerebral and craniofacial involvement are exceedingly rare, radiologist must suspect from other unusual involvement such as craniofacial and muscular location in patients with cerebral AE.

Cysticercosis is a systemic parasitic infestation caused by ingesting the eggs of the pork tapeworm, Taenia solium. The central nervous system (CNS) is the most important primary site of infection and disease can present with solitary or multiple space-occupying lesion. Other organs like subcutaneous tissues, muscles, heart, liver, lungs, and peritoneum are more frequently affected but maxillofacial region involvement is rare. The diagnosis of cysticercose is evoked on US examination and CT scan, but confirmation is only possible by Fine needle aspiration cytology [FNAC] or histological examination in case of surgical removal of the oral lesion which can identify the Taenia solium larva. Solitary intramuscular cysticercosis in maxillofacial region, without involvement of CNS is a rare entity. We present a rare case of solitary temporalis muscle involvement without any systemic or neurologic infestation, which presented the diagnostic and therapeutic dilemma along with review of literature., (Copyright © 2017 Elsevier Masson SAS.
