BACKGROUND: Inflammatory back pain is a condition characterized by inflammation of the sacroiliac joints and lower spine. It is frequently seen in patients with spondyloarthropathies like ankylosing spondylitis, psoriatic arthritis, enteropathic arthritis and reactive arthritis. Inflammatory back pain can be caused by many other conditions like infection and crystal deposition such as gout. In this case, it is difficult to specifically identify gout as a cause by ordinary imaging like magnetic resonance imaging (MRI) or ultrasound...

Endoscopic retrograde cholangiopancreatography (ERCP) is a commonly used diagnostic and therapeutic technique but it is not free of complications. Subcapsular hepatic haematoma is a rare but potentially fatal complication. A 71-years-old male patient resorted to the emergency department 36 hours after an uneventful ERCP presenting with severe abdominal pain and haemoglobin drop. Abdominal ultrasound and CT scan diagnosed a subcapsular hepatic haematoma. The patient was haemodynamically normal and was successfully treated with a conservative management...

In patients with silicone breast implants, implant rupture can occur, which can be intracapsular or extracapsular. Following implant rupture, silicone can travel through the lymphatic system into regional and distant lymph nodes. The purpose of this pictorial essay is to present findings of silicone implant rupture with intramammary and systemic silicone deposition as seen on dual energy CT (DECT), US, mammogram, PET/CT and MRI. We include imaging findings of silicone deposition in the breast in cases of intracapsular and extracapsular rupture...

The authors report a case of an orbital metastasis from an occult breast carcinoma. A 66-year-old woman presented with a growing left orbital tumour. Orbital CT scan was consistent with lymphoma. However, ocular pathology revealed small neoplastic cells showing an 'indian file pattern' suggestive of metastatic carcinoma and immunohistochemistry was positive for CK7, CK CAM5.2 and oestrogen receptor. A systemic evaluation was then performed with mammogram, breast ultrasound and MRI considered normal. An exhaustive systemic evaluation revealed multiple bone lesions, a right axillary lymph node lesion, which presented the same pattern on pathology and immunohistochemistry, with no evidence of a primary tumour...

Pancreatic neuroendocrine tumors (pNETs) constitute a heterogenous group of malignancies with varying clinical presentation, tumor biology and prognosis. The incidence of pNETs has steadily increased during the last decades with an estimated incidence 2012 of 4.8/100,000. Recent whole genome sequencing of pNETs has demonstrated mutations in the DNA repair genes MUTYH and point mutations and gene fusions in four main pathways from chromatin remodeling, DNA damage repair, activation of mechanistic target of rapamycin (mTOR) signaling and the telomere maintenance...

Rheumatic disorders comprise a number of diseases that range from benign, mildly symptomatic degenerative disease to severe systemic disorders such as giant-cell vasculitis with dramatic consequences such as acute blindness. The former is relatively common, whereas the latter is rare. In between, commonly encountered disorders such as rheumatoid arthritis and the various spondyloarthritides, with or without peripheral enthesitis, are daily challenges for the caring physician. Clinical evaluation is of utmost importance and is constantly described under the form of specialist guidelines in all parts of the world...

RATIONALE: Mild-to-moderate alcoholic cirrhosis of the liver is related to spontaneous intracerebral hemorrhage (ICH). In terms of spontaneous brainstem hemorrhage, pontine is considered as the most common site in contrast to medulla oblongata where the hemorrhage is rarely seen. This rare primary medullary hemorrhage has been attributed so far to vascular malformation (VM), anticoagulants, hypertension, hemorrhagic transformation, and other undetermined factors. PATIENT CONCERNS: Herein, we describe a 53-year-old patient with 35-year history of alcohol abuse was admitted for acute-onset isolated hemianesthesia on the right side...

Acute lobar nephritis (ALN) is a focal interstitial bacterial infection of the renal parenchyma. ALN is described as a midpoint between an acute pyelonephritis and renal abscess. ALN is underdiagnosed in children due to both non-specific symptoms and negative urinalysis/bacteriuria laboratory findings. The gold standard for diagnosis of ALN is CT scanning, however MRI can be considered to avoid radiation exposure. Diagnosing ALN is relevant, because it requires prolonged antibiotic treatment. Insufficient antibiotic treatment could cause renal scarring and subsequent hypertension or renal failure...

INTRODUCTION: Kidney cancer accounts for approximately 2-3 % of all types of cancers. Renal tumors prevalence and especially the prevalence of small renal tumors, is on the rise. About half of the tumors currently diagnosed are smaller than 4 cm. Minimally invasive methods of radiofrequency ablation technology were recently developed for the treatment of small renal tumors and are characterized by reducing the surgical and anesthetic risk. The ablation is performed with a percutaneous approach guided by ultrasound, CT or MRI...

The most common benign liver tumours are haemangiomas, focal nodular hyperplasia and hepatocellular adenoma. We perform a review of the literature and show the current diagnostic and therapeutic modalities based on the EASL Clinical Practice Guideline. With the widespread use of ultrasound, the detection of liver lesions is increased. They are usually found in women of childbearing age with atypical abdominal pain or incidentally. Contrast-enhanced US, CT or MRI are usually necessary for differential diagnosis...

Desmoid-type fibromatosis (DF), also known as aggressive fibromatosis, is a locally aggressive benign fibroblastic neoplasm that can infiltrate or recur but cannot metastasize. It is rare, with an estimated annual incidence of two to four new cases per million people. Most DFs occur sporadically, but it may also be associated with the hereditary syndrome familial adenomatous polyposis. Treatment is necessary when the disease is symptomatic, especially in case of compression of critical structures. When possible, surgical resection is the treatment of choice; however, recurrence is common...
