Benign ovarian lesions with restricted diffusion.

Developments in magnetic resonance imaging have expanded its role in the assessment of the female pelvis, including the diagnosis of ovarian lesions. In this setting, diffusion-weighted imaging has proven its diagnostic value, which is particularly important in differentiating between benign and malignant ovarian tumors. In general, the latter show restricted diffusion, whereas the former do not.

Dynamic magnetic resonance imaging of the female pelvic floor-a pictorial review.

Pelvic floor dysfunctions represent a range of functional disorders that frequently occur in adult women, carrying a significant burden on the quality of life, and its incidence tends to increase attending to the expected aging of the population. Pelvic floor dysfunctions can manifest as incontinence, constipation, and prolapsed pelvic organs. Since pelvic floor weakness is frequently generalized and clinically underdiagnosed, imaging evaluation is of major importance, especially prior to surgical correction.

Recurrent giant cell tumour of the maxillary sinus and pterygoid process treated with denosumab.

We report the case of a 74-year-old man with a giant cell tumour (GCT) of the right maxilla and pterygoid process. The patient presented to the maxillofacial and head and neck surgery clinic with an ulcerated lesion of the hard palate. Initial workup with CT revealed a mass within the right maxillary sinus and pterygoid process with associated bone expansion and erosion.

Atypical mandibular metastasis as the first presentation of a colorectal cancer.

We describe a case of a 70-year-old man presenting with a mandibular metastasis as the first sign of a mucinous adenocarcinoma of the rectum. After 6 months of a protracted toothache, the patient presented with a palpable mandibular mass and trismus, precluding adequate clinical evaluation. A CT scan was performed, and imaging findings suggested an aggressive primary jawbone tumour, most likely an osteosarcoma.
