Odontogenic-Like Pain in Partial Edentulism: An Unusual Presentation of Diffuse Large B-Cell Lymphoma of the Mandible.

Primary bone lymphoma is a rare entity and it usually occurs in long bones. Primary mandibular involvement is very rare, and it usually shows unspecific features, mimicking odontogenic inflammatory lesions. We present the unusual case of a diffuse large B-cell lymphoma (DLBCL) of the right mandibular body in a 91-year-old woman, who presented with acute pain in the mandibular region initially suspicious for odontogenic abscess.

Reported and Unreported Potentially Important Incidental Findings in Urgent Nonenhanced Abdominal CT for Renal Colic.

Objective: The aim of the study was to retrospectively evaluate the prevalence of reported and unreported potentially important incidental findings (PIFs) in consecutive nonenhanced abdominal CTs performed specifically for renal colic in the urgent setting.

Methods: One radiologist, blinded to the finalized report, retrospectively re-evaluated nonenhanced abdominal CTs performed from January to December 2017 on adult patients from the emergency department with the specific request of urgent evaluation for renal colic, searching for PIFs.

Results: The CTs of 312 patients were included in the study.

Patient Perception of Musculoskeletal MR: A Survey Research.

Background: When undergoing magnetic resonance (MR) exams, patients need to lie still in a noisy and enclosed environment for a long time. This condition, together with the anxiety burden related to the possible implications of the scan results, can entail a diagnostic outcome of poor quality.

Objective: The aim of the study was to evaluate the personal perception and experience of adult patients undergoing unenhanced musculoskeletal MR.

Paediatric gastric trichobezoar: the Rapunzel syndrome A report of two cases.

Rapunzel syndrome is a rare case of bowel obstruction resulting from hair ingestion (Trichobezoar). The obstruction can occur in any level of intestinal tract, but usually the stomach is primary involved. This syndrome is usually reported in patients affected by Trichotillomania or Pica syndrome, an obsessive-compulsive disorder that are characterized by an irresistible need to eat body hairs or non-digestible substances 1.

Radiological exams on end-stage oncologic patients before hospice admission.

Purpose: To evaluate frequency, type, and cost of diagnostic and interventional radiological exams performed on end-stage oncologic patients in the 90 days before Hospice admission.

Materials And Methods: Data of patients admitted to Hospice from January 2012 through June 2013 (18 months) were cross-checked with data from the digital archive of the Radiology Department. Frequency and type of exams performed before admission were analyzed across three 1-month periods, namely M, M, M, corresponding to 90-61, 60-31 and 30-1 days before admission.

Iatrogenic Coagulopathy and the Development of Posterior Reversible Encephalopathy Syndrome after L-asparaginase Chemotherapy.

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological syndrome mostly related to hypertension, eclampsia, renal failure, or to chemotherapy and/or immunosuppressive drugs. Although the PRES pathophysiology is multifactorial, hypertension and endothelial dysfunction are hypothesized to be the pivotal factors. Here we report a case of PRES in an adult patient after chemotherapy (Escherichia coli L-asparaginase [L-ASP], daunorubicin, vincristine, and intrathecal methotrexate) for acute lymphoblastic leukemia.

Large bilateral internal auditory meatus associated with bilateral superior semicircular canal dehiscence.

Superior semicircular canal dehiscence and an abnormally wide internal auditory meatus are clinical entities characterized by vestibular and cochlear symptoms. These symptoms are induced by hypersensitivity of labyrinthine receptors secondary to a bone defect of the otic capsule. We report the case of a 41-year-old man with congenital right-sided hearing loss who presented with bilateral superior semicircular canal dehiscence that was associated with wide, bulbous internal auditory meatus and a loss of the bony wall separating the lateral end of the meatus from the cochlea.

Prevalence of double pituitary adenomas in a surgical series: Clinical, histological and genetic features.

Background: The term double pituitary adenomas (DPA) is usually referred to those rare lesions showing two distinct cellular components. Genetic background may sustain the proliferation of more than one cell at the same time but no information is available on the presence of aip mutations in these patients.

Aim: We report the prevalence and the endocrinological, neuroradiological, histopathological and genetic features of DPA detected in a large surgical series.

Endonasal approaches to the sellar and parasellar regions: closure techniques using biomaterials.

Purpose: We reviewed the clinical outcomes resulting from various closure techniques used following endoscopic endonasal surgery for lesions in the sellar and parasellar regions. We compared our current closure technique, which uses a biological matrix of native equine collagen (TissuDura) fixed with fibrin sealant (Tisseel), with the technique we employed previously, using autologous materials, in order to assess the comparative efficacy and tolerability of both methods over the medium- to long-term.

Methods: A review was conducted of all cases of endonasal endoscopic intervention carried out in our institution between 1997 and 2007.

Varicella zoster virus meningo-encephalo-myelitis in an immunocompetent patient.

Objective: To describe clinical, MRI and cerebrospinal fluid (CSF) features of a varicella zoster virus (VZV) related meningo-encephalo-myelitis (MEM) without rash in an immunocompetent female.

Patient: An 85 year old immunocompetent woman with mild hyperthermia and acute, severe MEM.

Intervention: Serum antibodies and CSF PCR were searched for several viruses.

Cognitive memory control in borderline personality disorder patients.

Background: It has been demonstrated that the mechanism of cognitive memory control in humans is sustained by the hippocampus and prefrontal cortices, which have been found to be structurally and functionally abnormal in borderline personality disorder (BPD). We investigated whether the memory control mechanism is affected in BPD.

Method: Nineteen Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV BPD patients and 19 matched healthy controls (HC) performed a specific think/no-think paradigm exploring the capacity of remembering and suppressing pair of words previously learned.

Silent familial isolated pituitary adenomas: histopathological and clinical case report.

Familial isolated pituitary adenoma (FIPA) is a rare condition independent of Carney Complex or MEN1. An international multicenter study recently described 28 nonfunctioning pituitary adenomas in 26 families with only two homogeneous nonsecreting phenotype families consistent of silent GH and silent gonadotroph adenomas, respectively. We present the clinical, genetic, and morphological analysis of two silent pituitary adenomas occurring in a man and his daughter, and discuss the differential diagnosis associated with their histological, immunohistochemical, and ultrastructural features.

Double stenting procedure and coil embolization in a patient with carotid stenosis and incidental ipsilateral intracranial aneurysm. A case report and dosimetric evaluation.

We describe a case of incidental detection of an intracranial left ICA wide-necked aneurysm during digital subtraction angiography performed to assess a sub-occlusive and calcified stenosis in the extracranial portion of the same artery. Angioplasty and stenting of ICA stenosis, plus intracranial stent deployment across the aneurysm neck was performed during the same procedure. Aneurysm coil embolization was postponed to a further session one month later.

A study on maximum skin dose in cerebral embolization procedures.

Background And Purpose: It is essential to measure the skin dose of radiation received by patients during interventional neuroradiologic procedures performed under fluoroscopic guidance, such as embolization of cerebral aneurysms, which is regarded as a high-dose interventional radiology procedure. In this study, we report a method for evaluating maximum skin dose (MSD), an ideal marker of radiation-induced effects, based on an innovative use of radiochromic films.

Materials And Methods: Forty-eight procedures were studied in 42 patients undergoing embolization of cerebral aneurysms.

Contrast-enhanced versus conventional and color Doppler sonography for the detection of thrombosis of the portal and hepatic venous systems.

Objective: We conducted a prospective study to compare sonography, color Doppler sonography, and contrast-enhanced sonography for the detection and characterization of portal and hepatic vein thrombosis complicating hepatic malignancies.

Subjects And Methods: Three hundred sixteen patients with biopsy-proved hepatic tumors were studied at baseline and 3 months later with sonography, color Doppler sonography, and contrast-enhanced sonography. Thrombosis was defined as the presence of intraluminal echogenic material at sonography, absence of intraluminal color signals at color Doppler sonography, and presence of nonenhancing intraluminal area at contrast-enhanced sonography.
