Congenital pulmonary adenomatoid malformation (CPAM) is a congenital lung malformation that is distinguished by abnormal airway patterning during branching morphogenesis. It may lead to significant morbidity and mortality in infants due to complications such as pulmonary infections, lung hypoplasia, respiratory distress, and fetal hydrops. The diagnosis is usually prenatal thanks to morphological ultrasound; in postnatal, the anomaly may remain asymptomatic or show respiratory signs or complications. The postnatal diagnosis is based on computed tomography. In this article, we report a case of congenital pulmonary adenomatoid malformation in a 7-month-old patient who presented respiratory distress that is due to voluminous infected pleural effusion. The diagnosis of CPAM was suspected at the initial CT and confirmed at the control CT that was realized after treatment of the infection. The therapeutic management of CPAM is depending on the severity of complications and its evolution.

Epidermoid cysts are slow-growing congenital tumors developed from ectodermal inclusions. They usually sit at the cerebellopontine angle or basal cistern, their location in the fourth ventricle are exceptional.We report the case of a 44-year-old patient admitted to the Neurosurgery department for chronic daily headaches with visual impairment recently aggravated by cerebellar stato-kinetic syndrome.The diagnosis of epidermoid cyst of the fourth ventricle was suspected on MRI especially in diffusion sequence and then confirmed by the anatomopatological studies. Subtotal surgical excision was performed. The evolution was marked by the disappearance of clinical signs. Radiological and clinical follow up were indicated.
