Большая ладьевидная ямка была выявлена при многосрезовой компьютерной томографии у 2 пациентов, обратившихся в медицинский центр в связи с патологией околоносовых пазух. Ее появление происходит во время развития базилярной части затылочной кости и тела клиновидной кости в эмбриогенезе. На компьютерных томограммах ямка имеет вид краевого дефекта на вентральной поверхности ската черепа. Практическим врачам-рентгенологам следует интерпретировать подобную находку как врожденную аномалию развития, а не инвазивное патологическое поражение.

Fossa navicularis magna was detected in multislice spiral computed  tomography in two patients who turned to the medical centers with  pathology of the paranasal sinuses. Its appearance is determined during  the development of the basilar part of the occipital bone and the body of the sphenoid bone in embryogenesis. This fossa has the  appearance of an edge defect on the ventral surface of the clivus in  CBCT scans. Practical radiologist should interpret such a finding as a  congenital anomaly of development, but not as an invasive lesion.
