Orbital volume and shape in Treacher Collins syndrome
2018
Orbito-palpebral reconstruction is a challenge in Treacher Collins syndrome (TCS). This study investigates orbital phenotypes in TCS using cephalometry and orbital shape analysis. Eighteen TCS and 52 control patients were included in this study, using the Dr Warehouse database. Orbital cephalometry was based on 20 landmarks, 10 planes, 16 angles, and 22 distances. Orbits were segmented. Registration-based, age-specific mean models were generated using semi-automatic segmentation, and aligned and compared using color-coded distance maps - mean absolute distance (MAD), Hausdorff distance (HD), and Dice similarity coefficient (DSC). Symmetry was assessed by mirroring and DSC computing. Central…
Association between condylar asymmetry and temporo- mandibular disorders using 3D-CT
2011
Objectives: Using reconstructed three-dimensional computed tomography (3D-CT) models, the purpose of this study was to analyze and compare mandibular condyle morphology in patients with and without temporomandibular disorder (TMD). Study Design: Thirty-two patients were divided into two groups: the first comprised those with TMD (n=18), and the second those who did not have TMD (n=14). A CT of each patient was obtained and reconstructed as a 3D model. The 64 resulting 3D condylar models were evaluated for possible TMD-associated length, width and height asymmetries of the condylar process. Descriptive statistics were used to assess the results and student’s t tests applied to compare the tw…
Conservative vs. Surgical Management of Post-Traumatic Epidural Hematoma: A Case and Review of Literature
2015
Patient: Male, 30 Final Diagnosis: Acute epidural hematoma Symptoms: — Medication: — Clinical Procedure: Observation Specialty: Neurosurgery Objective: Unusual clinical course Background: Trauma is the leading cause of death in people younger than 45 years and head injury is the main cause of trauma mortality. Although epidural hematomas are relatively uncommon (less than 1% of all patients with head injuries and fewer than 10% of those who are comatose), they should always be considered in evaluation of a serious head injury. Patients with epidural hematomas who meet surgical criteria and receive prompt surgical intervention can have an excellent prognosis, presumably owing to limited unde…
Pre-operative evaluation of the volume of bone graft in sinus lifts by means of CompuDent
2009
Objective: This study aims to evaluate the usefulness of the CompuDent program in determining the pre-operative volume of bone graft in maxillary sinus floor lifts, and to calculate the volume of graft necessary for rehabilitation using varying lengths of implants. Study design: Based on the CompuDent program, we calculated the volume of graft necessary for 47 sinus lifts. This volume was measured in order to raise the floor of each sinus to 13.4 and 15 mm in height. Results: The average volume of graft in order to achieve a lift of 13?4 mm was 2.42 cm³ for the right maxillary sinus, with a range from 1.4 cm³ to 4.1 cm³, and 2.50 cm³ for the left maxillary sinus, with a range from 1.04 cm³ …
Ruptured angiomyolipoma of the kidney: a rare differential diagnosis of flank pain.
2017
Angiomyolipomas (AMLs) of the kidney are typically benign and rare, with an incidence of 2% of all renal masses [1]. They are associated with tuberous sclerosis in about 20% of cases. If ruptured, ...
Brain damage in hanging: A new CT finding
2000
We report a 23-year-old man who attempted suicide by hanging. There have been few reports of involvement of the brain parenchyma shown on CT, all showing ischaemic lesions. This is the first report of multifocal intracerebral haematomas due to hanging seen on CT.

Peliosis hepatis: spectrum of imaging findings
2006
OBJECTIVE. It is important to recognize the imaging characteristics of peliosis hepatis because peliotic lesions may mimic several different types of focal hepatic lesions CONCLUSION. We illustrate the spectrum of imaging findings of peliosis hepatis, including sonography, CT, MR, and angiography.
