Epidermoid cyst of the presacral space is a rare congenital lesion of ectodermal origin. Presacral epidermoid cysts have been previously reported in women, however are extremely rare in males. We report a case of presacral epidermoid cyst in a 55-year-old male who presented to our emergency department with acute urinary retention and history of chronic constipation. A non-contrast computed tomography scan was performed with suspicion of urolithiasis, which revealed a well circumscribed low attenuation presacral mass...

AIM: According to German guidelines, I-123-MIBG scintigraphy in neuroblastoma (NB) is preferably performed as early (about 4 h p.i.) and late (24 h p.i.) planar imaging and single- photon emission computed tomography (SPECT) or SPECT/CT 24 h p.i. This study evaluated if the work-up could be reduced to a single timepoint. METHODS: Retrospective analysis of 37 examinations in 26 patients (f:8; m:18; age, 0.5-23.5a) with NB (initial, 15; restaging, 22). All 74 (early + late) pairs of ventral/dorsal planar whole-body images were reviewed by 3 independent readers in random order blinded to clinical data (1, certainly physiological; 2, likely physiological; 3, likely malignant; 4, certainly malignant)...

PURPOSE: Variability in functional outcome after ileal pouch-anal anastomosis (IPAA) is to a large extent unexplained. The aim of this study was to use MRI to evaluate the morphology, emptying pattern and other pathology that may explain differences in functional outcome between well-functioning and poorly functioning pouch patients. A secondary aim was to establish a reference of normal MRI findings in pelvic pouch patients. METHODS: From a previous study, the best and worst functioning patients undergoing IPAA surgery between 2000 and 2013 had been identified and examined with manovolumetric tests (N = 47)...

A variety of neoplastic, inflammatory and congenital conditions can cause pituitary stalk thickening. Differentiating between these causes is important as targeted treatment may be offered. Diagnostic work-up consists of a thorough history, examination, biochemical analysis and imaging. We present the case of a 33-year-old male who presented with diabetes insipidus and had pituitary stalk thickening on magnetic resonance imaging. Further investigations revealed an elevated CSF βhCG, which raised the possibility of an intracranial germ cell tumor...

A 65-year-old male presented with an incidental magnetic resonance imaging (MRI) finding of a right renal pelvis (RP) tumor-like mass. He was subjected to nephrostomy tube (NT) placement due to hydronephrosis secondary to an impacted ureteral stone. NT was removed after successful Ho:YAG laser lithotripsy. Abdominal MRI performed 19 months later for another indication showed RP wall thickening/enhancement and an intrapelvic low-intensity linear structure presenting as a magnetic susceptibility artifact. He underwent diagnostic ureterorenoscopy/retrograde intrarenal surgery...

INTRODUCTION: Intussusception in adults is a rare condition, accounting for just 5% of all cases. Approximately 50% of cases of large intestine intussusception occur due to a malignant neoplasm. We present here a novel case report of colo-rectal intussusception arising secondary to a primary rectal melanoma. PRESENTATION OF CASE: We present the case of an 85 year-old patient, who underwent a colonoscopy for investigation of weight loss and altered bowel habit. At colonoscopy, a pigmented polypoid mass was visualised in the upper third of the rectum...

Bone sarcomas are extremely rare representing approximately 0.2% among all cancer types. Due to the rarity of these tumors both the patients and the physicians can overlook or misinterpret the first often unspecific symptoms of these tumors (pain, limping and swelling). Therefore, radiographic examination (X-ray and/or MRI) of the involved region in case of inexplicable symptoms is strongly recommended. The most common primary malignant bone tumor entity is osteosarcoma, followed by chondrosarcoma and Ewing sarcoma...

Lymphangiomatosis is an uncommon disease process characterized by multisystem lymphatic malformations that can involve numerous body systems, including organs, muscles, soft tissues, and bones. Involvement of the nervous system is rare and has even been previously described as a site of sparing. We present a case of a 24-year-old female with known lymphangiomatosis, presenting with acute onset of lower extremity paresthesias, weakness, and new urinary retention. MRI of the pelvis revealed lymphangiomatosis of the sacral plexus, which has not been previously reported...

BACKGROUND: Chronic recurrent multifocal osteomyelitis (CRMO), also known as chronic nonbacterial osteomyelitis, is a rare, noninfectious inflammatory disorder that causes multifocal bone lesions with swelling and pain. Lytic and sclerotic bone lesions could be found on X-ray. Short tau inversion recovery magnetic resonance imaging (STIR MRI) shows bone marrow oedema, bone expansion, lytic areas and periosteal reaction. CRMO is characterized by periodic exacerbations and remissions of unclear/unknown pathogenesis...

INTRODUCTION: Persistent Müllerian Duct Syndrome (PMDS) is a rare sexual disease. It is characterized by the presence of female reproductive structures such as uterus, cervix, fallopian tubes and upper part of vagina in a normal genotypically and phenotypically male. The diagnosis is usually incidental since the patients will present with normal external genitalia and secondary sexual characteristics. Imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT) scan, or ultrasound (US) could help in the diagnosis...
