“…On computed tomography intraorbital dermoid cysts, frequently located at the lateral canthus, rarely show bone sparing, calcification, or a fluid level [5]. Therefore, in this case a dermoid cyst was not very likely.…”

“…On CT they are diffuse hyperdense masses with irregular margins and show mottled contrast enhancement (Atlas et al 1987). 8 On CT dermoid cysts have well defined margins and appear cystic, with the density of their center ranging from CSF to that of fat (Chawda and Moseley 1999 Table I shows CT scan of the study patients it was observed that, in malignant cases majority 9(12.9%) patients done retinoblastoma followed by 8(11.1%) optic nerve glioma D/D meningioma, haemangioma.

Background: CT-Scan for the detection of orbital mass among pediatric patients is very important noninvasive radiological modality. The purpose of the study was to find out CT-Scan findings of orbital mass among pediatric patients in a tertiary care hospital.Methodology: This is a cross sectional study was carried out in Ophthalmology and Radiology and Imaging department of National Institute of Ophthalmology (NIO) from January 2012 to December 2013. All the patient below 18 years of age presented with suspected orbital mass at Ophthalmology and Radiology and Imaging department of NIO and performed CT- Scan of orbit for diagnosis of the disease and also done histopathology after operation was enrolled in this study.Results: In this study it was observed that a total of 29 cases identified as malignant evaluated by CT, among them 27 cases were true positive and 2 cases were false positive. Benign was found in 41 cases evaluated by CT scan, out of which 1 false negative and 40 cases were true negative. The sensitivity in diagnosis of orbital tumor by CT was 93.3%.Conclusion: The sensitivity in diagnosis of orbital tumor by CT was high and is a useful method in the differentiation between benign and malignant orbital mass.Anwer Khan Modern Medical College Journal Vol. 8, No. 1: Jan 2017, P 17-23

“…The dermoid cysts contain extra dermalis and produce keratin. Most of the cysts contain blood vessel, hair follicles fat tissues, collagen sebaceous gland and fat tissue [31,32]. The CT and MRI finding is one of the key to define the differential diagnosis of dermoid and epidermoid cyst with others benign and malignant tumors of the orbit.…”

Purpose: To valuate four-quadrant location method in diagnosis and differential diagnosis of the orbital tumor by comparison study combining CT and MRI with pathology. Materials and methods:Data of 87 patients (44 female and 43 males), aged 1 to 84 years were recruited in this study, including the computed tomography(CT), Magnetic resonance imaging (MRI), and histopathology diagnosis. All orbital tumors were verified radiologically and pathologically in the Hospital of Jinggangshan University from Sep-2008 to April-2016 patients underwent CT scanning (31 Conventional CT and 18 dynamic contrast enhancements CT) and 38 patients underwent MR Imaging (35 dynamic contrast enhancement MRI and 3 conventional MRI). The clinical data were retrieved from the medical record. We classified the orbital region according to four-quadrant and eight-space (FQES) division and traditional muscleconal division with center point of optic nerve. Results:Among the 87 cases of the orbital tumors, 70 cases (80.45%) were orbital benign tumors and 17 cases (19.54%) were malignant tumors. Regarding the location of the orbit, 41 lesions (47.12%) were in superolateral, 18 lesions (20.68%) were in inferolateral, 16 lesions (18.39%) were in inferomedial, 8 lesions (9.19%) were in superomedial, 3 lesions (3.44%) were in globe, 1 lesion (1.14%) was in optic nerve. The most common tumors are hemangiomas (total 36 cases: 12 in inferolateral, 8 in inferomedial, 9 in superolateral, 7 in superomedial) and 9 cases of pleomorphic adenoma were in superolateral, 9 cases of dermoid cyst ( 7 in superolateral and in 2 inferomedial), 5 cases of inflammatory pseudotumor (4 in superolateral and 1 in inferomedial), 7 cases of lymphoma (3 in superolateral, 2 in inferolateral and 2 in inferomedial ), 3 cases of adenoid cystic carcinoma in superolateral, 3 caese solitary fibrous tumor ( 2 in suprolateral and 1 in inferomedial), 3 cases lipoma (1 in superomedial, 1 in superolateral and 1 in inferolateral), 2 cases choroidal melanoma were in globe, 1 case of metastasis in superolateral, 1 case of meningioma in optic nerve, 1 case of malignant melanoma was in superolateral. The orbital tumors appeared in orbit with mostly regular, oval and rounds shape, well defined margin. The size ranged from 0.8 mm × 4.5 cm to 4.5 cm × 2.0 cm. The CT revealed iso-density in 22, slightly high-density in 15, mixed density in 6, low density in 5 and high density in 1 lesion. Among them, 18 were contrast enhancements. On T1WI image, the MRI revealed low signal intensity in 23 cases, slightly low signal in 4 cases, iso signal intensity in 7 case, high signal intensity in 3 cases, mixed signal intensity in 1 case on T2WI, it revealed high signal intensity in 23 cases, slightly high intensity in 7 cases, low signal intensity in 4 cases, iso signal intensity in 3 cases, mixed signal intensity in 1 case. Among them, 35 contrast enhancement MRI and 3 were non contrast MRI. Benign tumor was diagnosed in 70 patients, of them 34 were male and 36 were female, and the mean age was 45.19 ...
