Giant Fibroid Mimicking a Gastrointestinal Stromal Tumor: A Diagnostic Dilemma.

Uterine fibroids are the most common benign pelvic tumors in females of the reproductive age group. Usually, fibroids are confined to the uterus. Here, we report an interesting and rare case of a large 17 cm abdominopelvic mass lesion that led to a diagnostic dilemma between a mesenteric gastrointestinal stromal tumor (GIST) and a uterine fibroid. We had a 26-year-old female who underwent an ultrasound examination of the abdomen as the initial imaging modality and was found to have an abnormally large solid abdominopelvic mass lesion. For further evaluation, a contrast-enhanced CT examination of the abdomen-pelvis was done. Initially, on first look, the mass was thought to be of mesenteric origin, but on further review of images, it was found to be of gynecological origin. Intraoperatively, the solid mass was seen attached to the uterine fundus and underwent excision. Histopathological examination confirmed the mass to be a uterine fibroid. This case study describes the uncommon appearance of this tumor in a young woman, including the clinical presentation, imaging, and surgical findings.

Optic Strut and Para-clinoid Region - Assessment by Multi-detector Computed Tomography with Multiplanar and 3 Dimensional Reconstructions.

PURPOSE: To evaluate thickness, location and orientation of optic strut and anterior clinoid process and variations in paraclinoid region, solely based on multidetector computed tomography (MDCT) images with multiplanar (MPR) and 3 dimensional (3D) reconstructions, among Indian population. MATERIALS AND METHODS: Ninety five CT scans of head and paranasal sinuses patients were retrospectively evaluated with MPR and 3D reconstructions to assess optic strut thickness, angle and location, variations like pneumatisation, carotico-clinoid foramen and inter-clinoid osseous ridge. RESULTS: Mean optic strut thickness was 3.64mm (±0.64), optic strut angle was 42.67 (±6.16) degrees. Mean width and length of anterior clinoid process were 10.65mm (±0.79) and 11.20mm (±0.95) respectively. Optic strut attachment to sphenoid body was predominantly sulcal as in 52 cases (54.74%) and was most frequently attached to anterior 2/5(th) of anterior clinoid process, seen in 93 sides (48.95%). Pneumatisation of optic strut occurred in 23 sides. Carotico-clinoid foramen was observed in 42 cases (22.11%), complete foramen in 10 cases (5.26%), incomplete foramen in 24 cases (12.63%) and contact type in 8 cases (4.21%). Inter-clinoid osseous bridge was seen unilaterally in 4 cases. CONCLUSION: The study assesses morphometric features and anatomical variations of paraclinoid region using MDCT 3D and multiplanar reconstructions in Indian population.
