“…Certain radiographic characteristics have been described in the literature [22,24,36,38,45]. Osborn et al concluded that dermoid contents usually resemble fat on CT and MRI whereas epidermoids resemble CSF [29].…”

“…Patients with dermoid cysts may either remain asymptomatic or present with headaches, epileptic seizures, signs of compression of neighbouring tissues, aseptic meningitis, transient cerebral ischemia as a result of vasospasm and even olfactory halucinations [11, 14, 18-20, 25, 33, 40, 45-47]. After rupture of these cysts, their fatty content disperses into the subarachnoid space and may be present in any of the cisterns and ventricles [17,23,30,36,38,39,43]. Most often the rupture occurs spontaneously although trauma, such as a closed head injury, has been implicated in certain instances (see patient 2) [25].…”

“…These acute symptoms associated with the presence of dermoids, their localisation and their rupture are well documented [1,2,5,14,15,17,18,20,23,26,33,[40][41][42]. Diagnostic findings were evaluated in the past but Gd Gadolineum, N/a not available, HCP hydrocephalus, n/v nausea/vomiting, DWI diffusion weighted imaging show strong individual variation [4,8,9,13,22,24,27,31,32,36,38,44,45]. The aim of this report is to contribute to the understanding of this complex disease by presenting a series of patients with distinct characteristics and to provide a brief literature overview.…”

“…A thin rim of calcification is frequently present (11,12). Enhancement after contrast administration is rare but has been also reported (10,12,13,23). In atypical cases, mainly once important differentials have been excluded, we emphasise the importance of certain radiological features that are the well circumscribed character of the lesion, its extra-axial site, the absence of surrounding edema and the peripheral site of calcifications if there are any.…”

ABSTRACTedema and no contrast enhancement were noted. There was a mass effect in the form of effacement of the left occipital horn and moderate midline shift (Figure 1). On MRI study, the lesion appeared to be extra-axial and getting in touch with an osteoma. Mass, measuring 55 x 40 x 52 mm, displayed high signal intensity on T2 weighted images and a low signal intensity on T1 weighted images (Figure 2A-C). There were many peripheral low signal abnormalities on flash 2d images suggesting calcifications (Figure 3). T1 weighted images with gadolinium showed peripheral enhancement. There was no surrounding edema. Radiologically, the mass does not resemble a special tumor and it was difficult to advocate a preoperative diagnosis (Figure 4). at surgery, a left temporoparietal craniotomy was done. We first noted the osteoma at the inner surface of the bone that erodes the dura. The tumour was extra-axial, well circumscribed, pearly white in colour, soft in consistency and avascular. It was completely removed. The tumor capsule was also separated from normal brain and excised. The presence of hair and pultaceous material within the tumor could make the surgical diagnosis of a dermoid tumor and this was confirmed by histological studies. The patient postoperative █ InTRODuCTIOnDermoid cysts are benign dysembryogenic tumors originating from ectopic inclusions of epithelial cells during closure of neural tube. They account for about 0.04 to 0.7% of all intracranial tumors (20) with a predilection in the cranial midline, the parasellar and sylvian cisterns (2, 9, 27). Commonly dermoid cysts have characteristic computed tomography (CT) and magnetic resonance imaging (MRI) features making their preoperative diagnosis straightforward although this was not possible in our case.█ CASE REPORT a 48-year-old female, with no past medical history, was referred to our department with complaints of headache, vomiting and visual disturbances that started six months prior to admission.On presentation, the patient was having no neurological deficit. Her general physical and systemic examinations were also normal. A CT of the brain showed a heterogeneous isohypodense left temporo-parietal lesion with an osteoma in front of it and some peripheral calcifications. No surrounding Intracranial dermoid cysts are benign, slow growing tumors derived from ectopic inclusions of epithelial cells during closure of neural tube. These lesions, accounting for less than 1% of intracranial tumors, have characteristic computed tomography (CT) and magnetic resonance imaging (MRI) appearances that generally permits preoperative diagnosis. However, the radiologic features are uncommon and the cyst can be easily misdiagnosed with other tumors in rare cases. Herein, we report a case of a left temporoparietal dermoid cyst in a 48-year-old woman that was peroperatively and histopathologically proven but not advocated on CT and MRI. Clinical, radiological and histopathological features of a dermoid cyst are reviewed.

A unique case of suprasellar dermoid cyst and familial hypercholesterolemia in a child is reported. Such an association, which strengthens the congenital hypothesis of dermoid cysts, could be a manifestation of a complex dyslipidemic inherited syndrome, at least in children. Surgical removal of the dermoid cyst which spilled cholesterol into the cavernous and intercavernous sinuses, allowed reduction of cholesterol levels in the postoperative period.
