Fitz-Hugh-Curtis syndrome with disseminated intra-abdominal gonorrhoea.

Neisseria gonorrhoea continues to be implicated in a large proportion of sexually transmitted infections worldwide. Prompt recognition of infection is required to prevent further complications which include pelvic inflammatory disease and less commonly, perihepatitis which is known eponymously as Fitz-Hugh-Curtis syndrome. Third generation cephalosporins such as ceftriaxone remain effective in the treatment of gonococcal infection, however failure in initiation of appropriate antibiotic therapy in a timely manner can result in further disseminated disease. We describe an atypical case of Fitz-Hugh-Curtis syndrome presenting with multiple intra-abdominal gonococcal collections. Our case highlights the importance of a detailed sexual history in the evaluation of acute abdominal pain in at-risk patient demographics.

Radiology-pathology correlation of endometrial carcinoma assessment on magnetic resonance imaging.

Endometrial carcinoma is the most common gynaecological cancer in developed countries. Most cases are low-volume/low-grade tumour at presentation; however, high-grade subtypes may present with locally advanced disease with higher propensity for spread outside of the pelvis. MRI has a role in local staging of the tumour and helping the clinicians in treatment decision making. This pictorial essay gives examples of endometrial carcinoma at different stages with histological correlation. It also explores the potential limitations and pitfalls of imaging in this context.

Imaging features of extramedullary plasmacytoma.

Extramedullary plasmacytomas are rare and can occur at any site. The imaging results are often nonspecific. This report highlights the radiographic, sonographic and cross-sectional imaging features of extramedullary plasmacytomas.

High-Resolution Magnetic Resonance Imaging of Scalp Arteries for the Diagnosis of Giant Cell Arteritis: Results of a Prospective Cohort Study.

OBJECTIVE: To examine the concordance between high-resolution magnetic resonance imaging (MRI) of the scalp arteries and temporal artery biopsy for the diagnosis of giant cell arteritis (GCA). METHODS: We conducted a prospective cohort study of patients with suspected GCA. Participants underwent high-field 3T MRI of the scalp arteries followed by temporal artery biopsy. Arterial wall thickness and enhancement on multiplanar postcontrast T1-weighted spin-echo images were graded according to a published severity scale (range 0-3). MRI findings were compared with temporal artery biopsy results and the American College of Rheumatology (ACR) criteria for GCA. RESULTS: One hundred seventy-one patients were included in the study. Temporal artery biopsy findings were positive in 31 patients (18.1%), and MRI findings were abnormal in 60 patients (35.1%). ACR criteria were met in 137 patients (80.1%). With temporal artery biopsy as the reference test, MRI had a sensitivity of 93.6% (95% confidence interval [95% CI] 78.6-99.2) and a specificity of 77.9% (95% CI 70.1-84.4). The corresponding negative predictive value of MRI was 98.2% (95% CI 93.6-99.8) and positive predictive value was 48.3% (95% CI 35.2-61.6). CONCLUSION: In patients with suspected GCA, normal findings on scalp artery MRI are very strongly associated with negative temporal artery biopsy findings. This suggests that MRI could be used as the initial diagnostic procedure in GCA, with temporal artery biopsy being reserved for patients with abnormal MRI findings.
