Ectopic hepatocellular carcinoma (HCC) is defined as HCC arising from hepatic parenchyma located in an extrahepatic organ or tissue without any communication with the mother liver. It is very rare and difficult to diagnose by imaging alone. We report a case of a rare ectopic HCC mimicking a right para-aortic retroperitoneal mass and present a review of the literature. It is about a 79-year-old female patient, who presented with a progressive enlarged right paraaortic retroperitoneal mass, thought first to be leiomyosarcoma of vena cava on imaging. Subsequently, high alpha-fetoprotein (AFP) level and biopsy allowed the diagnosis of primary extrahepatic hepatocellular carcinoma., (© 2024 The Authors.

Objective: To assess the value of referral strategies for axial spondyloarthritis (axSpA) in patients with suspicious chronic inflammatory low back pain (LBP), to estimate the value of inflammatory back pain (IBP) for referral, and to identify the predictive factors of the final diagnosis of axSpA in Middle Eastern Arab countries., Methods: The study was multicentric, prospective, and conducted in LBP first-line clinics (rheumatology, internal, family medicine, orthopedic surgery, neurosurgery, and neurology). Consecutive adult patients aged under 45years were included in case of LBP suspicious of inflammatory nature according to the first-line physician. The rheumatologist's final diagnosis was the gold standard. The diagnostic properties of ten referral strategies (Brandt I, II, III, Hermann, RADAR, RADAR 2/3, MASTER, Braun, CAFASPA, and ASAS) and of IBP were calculated. A multivariable logistic regression identified the clinical predictive factors of axSpA., Results: In 515 referred patients, axSpA was confirmed in 48%, refuted in 43%, and diagnosis remained inconclusive in 9%. The optimal referral strategy was the MASTER (PLR 3.3), which comprises IBP, good response to NSAIDs, positive HLA-B27, and SpA family history. Considering strategies without HLA-B27, the RADAR 2/3 had a PLR of 2.9 (IBP, good response to NSAIDs, any extra-musculoskeletal manifestation). The predictive factors for axSpA were MRI sacroiliitis, positive HLA-B27, high CRP, psoriasis, IBP, and longer symptom duration. Of all patients, 35% were self-referred, 16% were referred by primary care physicians, and 15% by neuro/orthopedic surgeons., Conclusion: Optimizing physicians' awareness of these clinical features may enhance referral in axSpA., (Copyright © 2023 Société française de rhumatologie.

Background: We report a case of osteitis fibrosa cystica, a rare benign resorptive bone lesion caused by hyperparathyroidism, that presented on imaging as an aggressive bone tumor., Case Presentation: The patient is a 51-year-old male complaining of severe sustained pain of the right hip region. Imaging studies were suspicious for a malignant tumor of the right iliac bone. Biopsy under CT guidance was performed and showed remodeled bone trabeculae with numerous osteoclasts, excluding bone tumor and raising the possibility of osteitis fibrosa cystica. Complementary tests disclosed elevated blood level of parathyroid hormone and a partially cystic enlarged left inferior parathyroid gland consistent with adenoma. After parathyroidectomy, the clinical symptoms were relieved and the radiological findings were significantly improved, which confirmed the diagnosis., Conclusions: Metabolic diseases-associated bone lesions should always be considered in the differential diagnosis of bone tumors, to avoid unnecessary surgeries and treatments.

We report for the first time a case of atypical unilateral sacroiliitis secondary to mechanical stress injury. Unilateral sacroiliitis can be caused by a variety of etiologies. The first diagnosis to rule out is infection since it requires urgent treatment to avoid its serious consequences. Spondyloarthritis can be manifested by unilateral sacroiliitis in its early stage. Sacral fractures should always be looked for on the imaging modalities performed. In our case, no signs of infection or systemic disease were found. No fracture was seen on the imaging examinations and we had negative cultures on the computed tomography-guided biopsy realized. A history of mechanical stress was the only clue found suggesting the diagnosis of a probable stress related sacroiliitis. A thorough review of the literature will be provided stating the different causes of sacroiliitis described till now, with discussion of this new reported entity., (Copyright Journal of Radiology Case Reports.)

Background: Premature ejaculation has a complex etiology, and its pathophysiology is still unclear, with penile hypersensitivity being the most accepted hypothesis. The aim was to investigate the efficacy and safety of a computed tomography-guided pudendal nerve block at the level of the sacrospinous ligament and the Alcock's canal in patients with premature ejaculation refractory to conventional pharmacological treatment. Methods: This is a prospective pilot study involving five patients suffering from premature ejaculation refractory to standard treatment and clinical features of pudendal nerve entrapment. A CT-guided infiltration of ropivacaine and methylprednisone was done at the levels of sacrospinous ligament and Alcock's canal. Intra-vaginal ejaculatory latency time (IELT) was recorded several times for each patient before and after infiltration. International Index of Erectile Function (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT) and Sexual Quality of Life-Male version (SQoL-M) questionnaire were also evaluated before and after infiltration. Results: Overall IELT differed significantly before and after treatment (21.94 vs 215.42 s; p  = 0.039). IIEF-5, PEDT and SQoL-M also differed significantly before and after treatment. No complications for the CT-guided infiltration were recorded. Conclusion: CT-guided pudendal nerve block at the sacrospinous ligament and the Alcock's canal was effective in improving premature ejaculation. Therefore, pudendal nerve entrapment may be a curable cause of sensory premature ejaculation.

Objective: To determine if discharge destination after hospitalization for hip replacement or repair influences the hospital readmission rate., Design: A retrospective cohort study that included consecutive patients with a primary diagnosis of hip replacement or repair who were discharged from the acute hospital in a 3-year period., Setting: Urban academic nonprofit hospital., Patients: Data for 606 orthopedic patients discharged alive from the acute hospital between January 2004 and September 2006 were abstracted from the University Health-System Consortium (UHC) Clinical DataBase/Resource Manager clinical database for the study hospital., Main Outcome Measures: Unplanned readmission rate to the study-site hospital within 180 days after discharge after hip replacement or repair., Results: Unplanned readmission within 180 days occurred at a rate of 8.3% and varied significantly by discharge destination: home 5.1%, home with home health care services 10.5%, skilled nursing facility 12.3%, inpatient rehabilitation 4.2%, and other 42.9%. Variables from the surgical admission that were significantly associated with higher risk of readmission included admission severity, burden of comorbidities, any days in the intensive care unit, long length of stay, and cost. When controlling for multiple independent risk factors, discharge to inpatient rehabilitation (P = .015) remained a significant independent predictor of lower risk of readmission within 180 days., Conclusion: Discharge to acute inpatient rehabilitation was associated with a lower risk of hospital readmission. Identification of patients with orthopedic procedures who may benefit from inpatient rehabilitation and further medical management before discharge from the acute hospital may be an important strategy in prevention of hospital readmission., (Copyright © 2010 American Academy of Physical Medicine and Rehabilitation.

To evaluate the efficiency and complication rate of two percutaneous treatments of osteoid osteomas, percutaneous trephine resection (PR) and interstitial laser ablation (ILA). Ethical review board was obtained for the retrospective study. One hundred and 26 patients were treated by PR (n = 26) or ILA (n = 100) under CT, with a median follow-up of 113 months for the PR group and 47 months for the ILA group. In the group treated by PR, the clinical success rate was 96% at 6-month and 95% at 24-month follow-up, with 12% (3/26) transient complications (one meralgia, two skin burns). One patient experienced immediate failure, and none had delayed failure. In the group treated by ILA, the clinical success rate was 96% at 6-month and 94% at 24-month follow-up, with 4% (4/100) transient complications (one common fibular nerve contusion, one hematoma, one infection and one tendinitis). Four ILA procedures were repeated, one because of initial failure and three because of recurrence (at 6.5, 15 and 32 months). Two were successful and two failed again. Failure was more frequent (p = 0.0094) in patients less than 18 years old, and in lesions with a nidus size of 12 mm or larger (p = 0.0022).

Embryonic development of arteries of the lower limb results from the union of dorsal and ventral systems, explaining many variations at different levels. Some of these are important to recognize during the radiological exam because they can affect therapeutic management. These variations are most often bilateral and symmetrical predominating at the popliteal and subpopliteal levels. Lippert classified them into three types: normal level of popliteal arterial branching, high division of popliteal artery, hypoplastic or aplastic branching with altered distal supply. The length of the tibioperoneal trunk may also vary, rarely measuring more than 5 cm. We report a case combining three variations, two of them previously described in the literature and the third one not yet reported: our patient presented four arteries due to early bifurcation of the peroneal artery.

We describe a case of arteriovenous fistula developing at the site of balloon dilatation immediately after percutaneous transluminal angioplasty of the superficial femoral artery. This occurred during an otherwise uncomplicated angioplasty. The fistula was treated by inflating a slightly larger balloon with a good clinical result as confirmed by color Doppler ultrasound. This uncommon complication of angioplasty is not widely recognized.

Vertebral arteriovenous fistulae are relatively rare, with limited experience in most centers. We report our experience in the treatment of a vertebral arteriovenous fistula treated by interventional method. A review of the literature is made and the etiology, presentation and treatment of this unusual lesion are discussed. The endovascular occlusion is now the treatment of choice of vertebral fistulae.
