We report a case of a 72-year-old male admitted in our Unit with anemia and a 10 cm liver neoplasm. Computed tomography scan showed 2 lesions respectively in the II, III and, VIII segment of the liver. Surgical resection of the larger liver mass was performed and the tumor appeared as a solid-cystic mass and a diagnosis of malignant mesenchymal tumor not otherwise specified, was made. One month later a Computed tomography scan detected a dishomogeneous gastric mass, 6 cm in diameter, in the greater curvature, confirmed by esophagogastroduodenoscopy...

Retroperitoneal fibrosis (RPF) is a very rare disease that is even more rare in the pediatric population. Even less common are idiopathic pediatric cases of retroperitoneal fibrosis, with a majority of reported pediatric retroperitoneal fibrosis cases being associated with secondary etiologies. We present an 11-year-old Caucasian female that was diagnosed with idiopathic retroperitoneal fibrosis using magnetic resonance imaging (MRI) to work-up severe bilateral hydronephrosis that was identified with retroperitoneal ultrasound...

Fistulous communications between the common iliac arteries and inferior vena cava are very uncommon and usually occur as a result of trauma, aneurysmal rupture, or endovascular repair. They can present with signs of high output cardiac failure including hypotension, venous congestion, and pulmonary hypertension. This case outlines the utility of CTA in diagnosing iliocaval fistulas and the importance of considering this diagnosis in a patient with signs of right heart strain and high output cardiac failure.

We report a case of vascular malformation arising from internal jugular vein discovered during radiological investigations for restaging of metastatic colon carcinoma of an adult male patient. Congenital absence of internal jugular vein is extremely uncommon. These developmental anomalies in general population are seen in about 0.05%-0.25%. The awareness of these vascular anomalies is extremely important to avoid unsafe complications, primarily in oncological patients, whom usually require the incannulation of neck veins for diagnostic procedures or intravenous therapy administration...

Chitayat syndrome is a rare genetic syndrome characterised by bilateral hyperphalangism, bronchomalacia, hallux valgus, and other facial dysmorphism including large anterior fontanelle, hypertelorism, and anteverted nostrils. Since the initial discovery, only few cases of Chitayat syndrome have been reported in the literature. Previous literatures showed the genetic link between 5 case reports, showing that a unique link of recurrent c.266A>G p.(Tyr89Cys) variant in the ERF gene may be the contributory genetic cause of Chitayat syndrome...

Round pneumonia is a disease commonly recognized in the pediatric age group, especially under the age of 8 years. Streptococcus pneumoniae is the most common agent causing this characteristic type of pneumonia. We herein report a case of a 6-year-old boy with only mild cough and low-grade fever who was then diagnosed with round pneumonia due to Chlamydia pneumoniae . He had multiple round opacities in the right lower lung field, and the symptoms subsided soon after oral administration of antibiotics.

To date, mammographic involvement in mixed connective tissue disease has not been described in the literature to the authors' knowledge. In addition, only 2 case reports have described panniculitis in mixed connective tissue disease. We present a patient with mixed connective tissue disease with coarse sheet-like calcifications on mammography bilaterally, which increased over time corresponding to rise in levels of anti-dsDNA. Biopsy showed fat necrosis with calcifications, chronic inflammation and fibrosis, vasculitis, as well as CD3, CD4, and CD8+ T cells and CD20+ B cells...

Nowadays tuberculosis has become a reemerging infectious disease due to the many forms of immunodeficiency. Patients with eating disorders like anorexia nervosa and bulimia are a susceptible group due to the immune impairment correlated with severe malnutrition and their prevalence and incidence is growing. We describe the case of a 31-year-old woman, with long-standing history of anorexia nervosa and bulimia, diagnosed with advanced pulmonary tuberculosis. This case underlines the importance on never neglecting even the slightest symptoms in patients with malnutrition and never excluding this pathology without a proper investigation...

Long-term cuffed hemodialysis catheters are being increasingly used in the management of patients with chronic kidney disease. These tunneled catheters are available in different types and characteristics. Patients undergo imaging, primarily chest radiographs to confirm the position of the catheter tip. It is essential to be aware of the normal imaging appearances of these catheters as they may simulate pathological appearance due to the shape of their tips. This knowledge will help avoid misdiagnosis and unnecessary medical interventions...

Remote Cerebellar Hemorrhage is a rare entity that manifests spontaneously after supratentorial craniotomy and spinal surgeries. We present a 53-year-old male who was admitted due to subdural hematoma along the left frontoparietotemporal convexity. After treatment of the subdural hematoma with craniotomy and evacuation, he developed remote cerebellar hemorrhage 1 week later. Brain computed tomography demonstrated the zebra sign. Follow-up imaging showed complete recovery without any neurologic symptoms or signs...

Frontal-orbital-ethmoid mucocele is a slow-growing retention cyst of the fronto-ethmoid complex secondary to blockage of the sinus ostia. It may produce significant disfigurement of the periorbital region necessitating surgical intervention. Prior to surgery, it is imperative to study the mucocele's extent through the variable patterns of ethmoid pneumatization as evident from clinical, imaging (computed tomogram) and endoscopic evaluation. This is illustrated in a case study of a 41-year-old woman presenting with fullness below the right eyebrow, progressive proptosis, and gaze restriction...

The mobile bearing Oxford Unicompartmental Knee Prosthesis (OUKP) is the most commonly used treatment of osteoarthritis confined to 1 compartment of the knee. Dislocation of the mobile bearing is an uncommon but recognized complication of the OUKP. Patients typically present with severe pain and reduced range of motion of the affected knee. Radiological evaluation of OUKP can be challenging and requires knowledge of the prosthesis components and common complication patterns. Dislocation of the bearing can easily be overlooked on plain radiographs as the bearing is radiolucent, distinguished only by radiopaque markers...

An osteoid osteoma is a benign bone tumor that arises from osteoblastic dysfunction and usually presents as nonspecific, nocturnal pain located in the diaphysis of long bones, with <1% occurring in the ribs. It is most commonly treated with nonsteroidal anti-inflammatory drugs or merely observed; when these treatments do no prove efficacious, either open surgery or interventional ablation are pursued. Herein, we report a rare case of an osteoid osteoma located in the rib of a 19-year-old male that was histologically diagnosed through computed tomography (CT)-guided biopsy...

The leakage of contrast material into the subdural space following intra-arterial or intravenous administration can present as hyperattenuating subdural collections on noncontrast head computed tomography (CT) scan, mimicking subdural hematomas. Such a finding can potentially initiate erroneous intervention or hinder thromboprophylaxis treatment. We report the time course of attenuation changes in enhancing subdural collections of a patient with suspected stroke following percutaneous coronary intervention...

Primary splenic angiosarcoma carries a poor prognosis and is among the rarest forms of malignancy. An overwhelming majority of patients with splenic angiosarcoma will develop metastases. However, osseous metastatic disease is rare. We present an 83 year old hispanic female who was diagnosed with primary splenic angiosarcoma on bone marrow biopsy performed for a hematologic workup. We highlight key historical, laboratory, imaging, and pathological features of splenic angiosarcoma. The synthesis of both imaging features and clinical history is essential for establishing early diagnosis in these patients...
