ABSTRACT
As we already stated previously, any process that affects the intracranial region may lead to lesions in more than one cranial nerve (CN) or structure, and when this occurs, the clinical presentation could be complex, causing a delay in the diagnosis. One example of this complexity is the isolated Horner's syndrome secondary to rhinosinusitis, which can be explained by Raeder syndrome affecting the third neuron of the oculosympathetic pathway. The sellar region includes the sella turcica and the pituitary gland (adenohypophysis and neurohypophysis); on the other hand, the parasellar region comprizes the cavernous sinuses, suprasellar cistern, hypothalamus, and ventral inferior third ventricle. It is noteworthy that the anatomic localization of the lesions during the clinical examination is essential for the differential diagnosis between sellar and parasellar lesions. In this way, due to the small size of the pituitary gland and its proximity to many important structures, the neuroimaging diagnosis is challenging.
