The detection of fetal anomalies has improved in the last years as a result of the generalization of ultrasound pregnancy screening exams. The presence of a cystic imaging in the fetal pelvis is a relatively common finding, which can correspond to a real congenital cystic lesion or result from the anomalous liquid accumulation in a whole pelvic organ, mainly the urinary bladder, the uterus, or the vagina. In selected cases with poor prognosis and/or inconclusive echographic findings, magnetic resonance may bring additional information in terms of the characterization, anatomical location, and real extension of the pathology...

BACKGROUND: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases...

The association of ipsilateral renal agenesis and cystic seminal vesicle is a rare congenital syndrome described by Zinner in 1914. The cases of two patients with this syndrome are presented, one of them associated with infertility, the other with cryptorchidism and testicular pain. A brief review of the literature is undertaken, regarding the main clinical and imaging implications, and the developmental anomalies that are involved in this unusual congenital anomaly are analyzed.

OBJECTIVE: To assess the diagnostic performance of the apparent diffusion coefficient (ADC) in predicting the Fuhrman nuclear grading of clear cell renal cell carcinomas (ccRCC). MATERIALS AND METHODS: A total of 129 patients who underwent partial and radical nephrectomies with pathology-proven ccRCC were retrospectively evaluated. Histopathological characteristics and nuclear grades were analyzed. In addition, conventional magnetic resonance imaging (MRI) features were assessed in consensus by two radiologists to discriminate nuclear grading...

An epidermoid cyst arising within an intrapancreatic accessory spleen (ECIAS) is rare, and also difficult to correctly diagnose before surgery. It is mostly misdiagnosed as a cystic tumor, such as a mucinous cystic neoplasm or as a solid tumor with cystic degeneration, such as a neuro endocrine tumor. We herein report a case of ECIAS and also perform a literature review of 35 reports of ECIAS. Although the preoperative diagnosis of ECIAS using conventional imaging is relatively difficult to make, careful preoperative examinations of the features on computed tomography and magnetic resonance imaging could lead to a correct preoperative diagnosis of ECIAS which might thereby reduce the number of unnecessary resections...

OBJECTIVE The aim of this study was to reappraise long-term treatment outcomes of stereotactic radiosurgery (SRS) for vestibular schwannomas (VSs). The authors used a database that included patients who underwent SRS with a unique dose-planning technique, i.e., partial tumor coverage designed to avoid excess irradiation of the facial and cochlear nerves, focusing on tumor control and hearing preservation. Clinical factors associated with post-SRS tumor control and long-term hearing preservation were also analyzed...

There is a wide group of lesions that may exist in the sellar and suprasellar regions. Embryologically, there is varying evidence that many of these entities may in fact represent a continuum of pathology deriving from a common ectodermal origin. The authors report a case of a concomitant suprasellar craniopharyngioma invading the third ventricle with a concurrent frontal lobe cystic dermoid tumor. A 21-year-old man presented to the authors' service with a 3-day history of worsening headache, nausea, vomiting, and blurry vision...

This is the case report of a 65-year-old man who experienced left calf pain after spraining his left ankle. On magnetic resonance imaging (MRI), a well-defined fluid collection was identified, with low intensity on T1-weighted images and very high intensity on T2-weighted images. On certain slices, a soft tissue mass in the proximal fibula was identified. Following resection of the fibular lesion, histological examination confirmed a benign tumor with cystic elements, described in the current pathology and radiology literature as juxta-articular myxoma...

Intramedullary hydatid cyst is extremely rare. We present a case of pathologically confirmed primary intramedullary hydatid cyst in an otherwise healthy patient. A 17-year-old boy presented with lumbar pain, weakness, and numbness in both lower limbs, and urinate difficulty interrupted for 2 years. The patient had no other signs of systemic hydatid cyst disease. An intramedullary cystic lesion was identified with magnetic resonance imaging and was shown to be a hydatid cyst by histopathologic examination after the surgical removal...

Cholangiocarcinoma is an uncommon primary malignancy of the biliary tract that is challenging to diagnose and treat effectively due to its relatively silent and late clinical presentation. The present study reports a case of a 60-year-old male with distal extrahepatic cholangiocarcinoma with a 3-week history of painless obstructive jaundice symptoms and subjective weight loss. Imaging revealed an obstructing lesion in the common bile duct, just distal to the entrance of the cystic duct. Pathology revealed moderately differentiated cholangiocarcinoma with two positive proximal resection margins...

Olfactory ensheathing cell tumor (OECT) is one of the most rare intracranial, extra-axial tumors located in the anterior cranial fossa. The present study reports a case of a 34-year-old female patient who presented with a history of hyposmia for 1 year, as well as a gradual dizziness and emotional lability for 2 months. Magnetic resonance imaging of the brain revealed a globose, well-defined cystic mass at the midline of the anterior cranial fossa, which was confirmed as an OECT by histology and was completely resected by bifrontal craniotomy...

Glomerular cysts are defined as a 2-3 times dilation of Bowman spaces and their presence in at least 5% of the glomeruli defines the kidneys as glomerulocystic (GCK). The association between cystic kidney disease and the tuberous sclerosis complex (TSC) is well known, but its presentation as a unilateral mass with glomerulocystic pattern is rare. We describe a case of an infant with a prenatal diagnosis of TSC, with a renal mass that was believed to be a renal tumor. A four-month-old infant with maternal history of TSC and prenatally diagnosed subependymal nodules and a right renal mass underwent nephrectomy...

Schwannoma are benign tumours of the nerve sheath. They are commonly found in the soft tissue, but its presence in the bone is extremely rare. We herein present a case of 34-year-old man with two adjacent pelvic subperiosteal schwannomas. Computed Tomography (CT) scan showed osseous pressure erosion and Magnetic Resonance Imaging (MRI) showed two cystic signal intensity lesions, one near superior aspect of right posterior iliac wing and another inferior to it with adjacent cortical pressure erosion. The tumour was excised en bloc and on histopathological examination, the diagnosis was confirmed as subperiosteal schwannoma...

This study aims to focus on a rare presentation of spinal hydatid cyst as cauda equine syndrome and misdiagnosed as intradural extramedullary (IDEM) benign lesion on magnetic resonance imaging. In this article, we report a case of spinal hydatid cyst masquerading as IDEM tumor, and intraoperatively, we accidently find clumped granuloma with severe arachnoiditis and hydatid cyst in lumber region, which was present as bilateral S1 radiculopathy with cauda equina syndrome. An 11-year-old boy who presented with symptoms and signs of cauda equina syndrome and planned for surgical excision...

AIM: To identify the multidetector computed tomography (MDCT) features of pancreatic neuroendocrine tumours (pNETs), which correlate with tumour histology and enable preoperative grading. MATERIALS AND METHODS: Thirty-nine patients with histologically confirmed pNET who underwent preoperative contrast-enhanced MDCT were included in this study. Nineteen tumours were classified as Grade 1 (G1) and 20 as Grade 2 (G2). Histopathology slides were reviewed to assess the intratumoural microvascular density (MVD) and the amount of tumour stroma...

Chest tomography (CT) using the controlled ventilation technique (CTCV) is a sensitive method to detect features of lung cystic fibrosis (CF) disease in infants with CF. However, this technique needs sedation and is not easily applied for the clinician who may need, in the follow-up, to evaluate more precisely lung disease in infants with CF. Thus, our study aims to evaluate if CT assessment of lung disease, without the need of sedation, during quiet breathing, using a semi-quantitative scoring system, is reproducible and may discriminate infants with CF from control infants at an early stage of the lung disease...
