Morel-Lavallée lesion after falling down stairs, diagnosed with ultrasound: A case report.

The Morel-Lavallée lesion is an uncommon closed degloving injury that most often occurs in the setting of high-energy trauma and can be associated with other traumatic injuries, including fractures of the pelvis, acetabulum, or femur. The superficial soft tissues are forcibly separated from the underlying deep fascia, resulting in damage to penetrating blood vessels and lymphatics. A fluid collection consisting of lymph, blood, and/or necrotic tissue subsequently develops and is most common in the region of the greater trochanter.

Mature cystic teratoma of the fallopian tube diagnosed preoperatively with computed tomography and ultrasound: A case report.

Mature cystic teratoma of the fallopian tube is extremely rare, with fewer than 100 cases reported in the English literature. Clinical symptoms are nonspecific, and the diagnosis is most often made after surgical resection. A preoperative diagnosis has the potential to aid with surgical planning and patient counseling.

Mimics and Pitfalls of Primary Ovarian Malignancy Imaging.

The complex anatomy and similarity of imaging features of various pathologies in the pelvis can make accurate radiology interpretation difficult. While prompt recognition of ovarian cancer remains essential, awareness of processes that mimic ovarian tumors can avoid potential misdiagnosis and unnecessary surgery. This article details the female pelvic anatomy and highlights relevant imaging features that mimic extra-ovarian tumors, to help the radiologists accurately build a differential diagnosis of a lesion occupying the adnexa.

Isolated Intravascular Prostate Carcinoma Recurrence Confirmed With 18F-Fluciclovine PET/CT and MRI.

Late recurrence of prostate cancer after remission with prior radical prostatectomy is uncommon. This is a unique case of biochemical recurrence after being in remission for 12 years. The patient presented with swelling of the right lower extremity with pelvic MRI demonstrating an arterially enhancing filling defect in the right common iliac.

Ectopic pituitary adenomas: common presentations of a rare entity.

Purpose: Ectopic pituitary adenomas (EPA) are rare tumors thought to arise from embryological remnants along the route of normal pituitary migration. Clinically, these tumors vary in hormonal activity and can exert mass effect based on location and size.

Methods: We performed a single-center retrospective analysis of patients with diagnosis of ectopic pituitary adenoma from 2001 to 2018.

Contribution of the SirA regulon to biofilm formation in Salmonella enterica serovar Typhimurium.

Orthologues of the Salmonella enterica serovar Typhimurium (S. typhimurium) BarA/SirA two-component system are important for biofilm formation and virulence in many gamma-Proteobacteria. In S.
