Intracranial tumors: A diagnostic challenge

Pseudoachalasia: a diagnostic challenge

Here, we present a case of a 78-year-old man that underwent gastrointestinal endoscopy because of one- monthhistory of dysphagia to liquids and solid foods with accompanying weight loss. On endoscopy, there was distalesophageal stenosis. Multiple biopsies were obtained. Histologic examination of the samples revealed normaltissue. The stenosis was treated by dilatation and abdomino pelvic comput...

Laryngeal Paraganglioma: A Diagnostic Challenge

Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...

Intracranial Cysts: An Imagery Diagnostic Challenge

Intracerebral cysts and cystic appearing intracerebral masses are common findings at routine cerebral imaging examination. We discuss here the most interesting aspects of some intracerebral cysts encountered in medical practice in terms of imaging, clinical and pathological description, and problems of differential diagnosis. On an almost routine basis, the neurologists have to deal with such d...

Intracranial arachnoid cyst on dental radiography: a diagnostic challenge.

Intracranial arachnoid cysts (IACs) can present as congenital asymptomatic lesions that may predispose them to present as an incidental finding during radiographic examination. On the other hand, IACs may also give rise to a series of neurologic symptoms depending on their size and location, such as vomiting, seizures, headache, and ataxia. Skull deformities, including macrocephaly, may occur a...
