Intracranial Cysts: An Imagery Diagnostic Challenge

Abstract

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 differentials. Therefore, we aim to mention here some of the frequently encountered diagnosis problems when a patient presents with a cystic cerebral mass.

A Rare Presentation of A Giant Epidermal Cyst of The Parietooccipital Region: A Case Reports

“…The typical CT aspect is a large homogenous hypodense non enhancing mass, with or without calcifications. 9, 11,12 Although the clinical course of epidermoid cysts referred to as a benign type, rarely, basal cell carcinoma, squamous cell carcinoma, epithelioid carcinoma, and other malignancies have been reported to be associated with these cysts. 13 For this reason, the treatment of choice is complete surgical removal to ensure complete removal and prevent the recurrence.…”

Spectroscopy and 3d-Ciss Sequence in Cystic Lesions of Brain: A Prospective Evaluation on Mri

“…Our findings were correlated with Alexandra Opri Gan, et al (2013). [2] Restricted diffusion was in favour of epidermoid cyst. Our findings were correlated with studies conducted by Ahmed Farid Yousef et al (2014).…”

“…Nevertheless, in unclear cases, biopsy or surgery and subsequent pathological analysis can establish the final precise diagnosis. [2] MR spectroscopy is a potential tool for differential diagnosis between brain abscesses and non-infectious lesions such as primary brain tumour, lymphoma, brain metastasis and tuberculoma. MRS provides information about the possible extent and nature of changes on a routine MRI scan by analysing the presence and/or ratio of tissue metabolites such as NAA, creatinine, choline and lactate, etc.…”

Ekstraaksiyel Beyin Tumorleri

“…Epidermoid kistler ektodermal orijinli, benign, konjenital kistlerdir [151]. En sık yerleşim yeri serebellopontin açıdır (yaklaşık %50).…”

“…Lipomlar homojen yağ dansite ve intensitesindedir. Perikallozal ve orta hat lokalizasyonunda [147,151,160]. BT'de kalsifikasyon ve kartilaj varlığı dermoidden ziyade teratomu düşündürür.…”
