An Infratemporal Meningioma: A Diagnostic Dilemma
A 46-year-old male presented with painless, recurrent bilateral ear discharge and an enlarging right temporal swelling. There were no neurological deficits. Imaging revealed an enhancing, soft tissue mass at the right infratemporal region involving the right temporalis muscle with a small, enhancing intradural component and associated hyperostosis of the greater wing of the right sphenoid bone. Tumour debulking of the right temporalis tumour was performed. Tumour invasion of the right temporalis muscle was noted intraoperatively. Histopathological result was consistent with fibrous meningioma WHO Grade 1 involving surgical...

Pancreatic Neuroendocrine Tumor presenting as a diffuse pancreatic enlargement, case report and review of literature
We present a case report of a 41-year-old female who underwent clinical work-up for abdominal pain, loss of appetite and weight loss for the past year. Ultrasound, computed tomography, and magnetic resonance imaging show diffuse homogenous pancreatic enlargement without contour deformity or a focal mass. Lymphoma and autoimmune pancreatitis were suggested based on imaging findings but IGg4 level and other lab data were normal. Endoscopic ultrasonography confirmed the diffuse enlargement of the pancreas without peripheral structures involvement. The pathological results of multiple fine-needle aspiration biopsy from all par...

Magnetic Resonance Imaging Appearance of Erythema Nodosum: A Case Report
We present a case of an 18-year-old female with a history of recurrent streptococcal infections over the years, who developed pain and swelling in the left ankle. To evaluate the persistent ankle swelling, the physician ordered a magnetic resonance imaging (MRI) of the left lower extremity. The MRI appearance of EN has not been described in detail in the literature so far. (Source: Journal of Radiology Case Reports)

Malignant transformation in a sciatic plexiform neurofibroma in Neurofibromatosis Type 1 - imaging features that aid diagnosis
A 41-year-old Asian male with NF1 and bilateral sciatic plexiform neurofibromas, presented with unintentional weight loss, increasing size of a left thigh mass associated with increasing pain and radiculopathy. MRI of the left thigh demonstrated imaging features suspicious of malignant transformation. The patient had a new left lung mass, demonstrating avid FDG uptake, raising suspicion for metastasis. Surgical resection of the left thigh mass confirms malignant transformation in a preexisting sciatic plexiform neurofibroma. Diagnosis of malignant transformation in a nerve sheath tumour can be challenging. MRI remains the ...

Extramedullary Plasmacytoma of the breast in a patient with Multiple Myeloma
Extramedullary plasmacytoma of the breast is rare. It is important to recognize the imaging findings and include it as a differential consideration in multiple myeloma patients with a breast mass. A 74-year-old woman undergoing chemotherapy for relapsed multiple myeloma presented with a palpable mass in her right breast. A screening mammogram four months prior was unremarkable. She underwent a diagnostic right mammogram which showed two well-circumscribed hyperdense masses. An ultrasound of the right breast showed mixed echogenic masses with indistinct margins and increased vascularity. Ultrasound guided biopsy confirmed t...

Penile Mondor's disease: Imaging in two cases
Penile Mondor ' s disease is a rare and under-recognized benign genital condition consisting of an isolated thrombosis of the dorsal superficial vein of the penis. Symptoms do not show distinctive features and there are asymptomatic cases. The patients usually present with a cord-like induration at dorsum of the penis. Diagnosis is usually made based on history and physical examination. The role of imaging in Mondor ' s disease is to identify the intravascular thrombus. In case of diagnostic uncertainty, Grey scale and Doppler ultrasound can be useful to detect the extent of thrombosis demonstrating echogenic material with...

Involvement of the Mediastinal Subpleural Pulmonary Parenchyma on Chest CT in COVID-19 patients: A Case Series
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). First identified in December 2019 in Wuhan, China, it has since become a global pandemic. Although the reference standard for SARS-CoV-2 diagnosis is real-time reverse transcription polymerase chain reaction (RT-PCR), computed tomography (CT) is recommended for both initial evaluation and follow-up. The CT findings in COVID-19 are varied, but typical ground-glass opacities are usually reported to occupy a peripheral costal subpleural distribution. Here we report eight confirmed COVID-19 c...

Appendicitis mimicking the CT appearance of an appendiceal mucinous neoplasm
We describe a case of a 50-year-old man who presented with a markedly dilated " mass-like " appendix with minimal inflammatory changes on a computed tomography scan. Radiological findings were suspicious for an appendiceal neoplasm/mucocele (i.e. low-grade mucinous neoplasm). However, the post-surgical histopathological diagnosis did not concur with the radiological diagnosis and instead demonstrated findings compatible with acute appendicitis without neoplastic change. In this case report we provide a histopathological correlation and an explanation as to how this may have happened with the hope of helping radiologists av...

Spontaneous bronchobiliary fistula: Case report
Bronchobiliary fistula (BBF) is a rare condition that results from the communication between the bile ducts and the bronchial tree. It is characterized by the presence of bile in the sputum as pathognomonic symptom, and it is often associated with suspicious pneumonia. The most common causes include infections (e.g. echinococcosis), hepatobiliary surgery, blunt torso traumas, tumors and percutaneous transhepatic procedures. Opinions about BBF treatment are still controversial as it can be treated by both conservative and surgical procedures, while pharmacological treatments are only rarely used. This case report presents a...

Co-existent Epicardial Paraganglioma and Anterior Mediastinal Thymoma
We report a case of a middle-aged woman with two mediastinal masses, originally believed to be a single tumor or primary malignancy with adjacent metastasis on Computed Tomography (CT) that were further delineated with Magnetic Resonance Imaging (MRI) and [68Ga]-DOTA-(Tyr3)-octreotate (DOTA-TATE) Positron Emission Tomography-Computed Tomography (PET-CT) and surgical pathology as two distinct entities: left epicardial paraganglioma and anterior mediastinal thymoma. A comprehensive discussion of both entities is included. (Source: Journal of Radiology Case Reports)

An aortic wall to vertebral body fistula presenting as a lytic lesion
There have been multiple reported cases of aortic fistulas but few cases of aorta to vertebral body fistulas and no aortic wall to vertebral body fistulas have been reported. Here we present a case of a patient who is status post thoracic aortic aneurysm (TAA) repair and found to have a lytic vertebral body lesion. Biopsy of the mass revealed blood products without evidence of malignancy and further investigation revealed a fistulous tract between the aortic wall and the vertebral body causing a vertebral body hematoma.

Atypical Unilateral Sacroiliitis Secondary to Mechanical Stress Injury
We report for the first time a case of atypical unilateral sacroiliitis secondary to mechanical stress injury. Unilateral sacroiliitis can be caused by a variety of etiologies. The first diagnosis to rule out is infection since it requires urgent treatment to avoid its serious consequences. Spondyloarthritis can be manifested by unilateral sacroiliitis in its early stage. Sacral fractures should always be looked for on the imaging modalities performed. In our case, no signs of infection or systemic disease were found. No fracture was seen on the imaging examinations and we had negative cultures on the computed tomography-g...

Isolated thoracic duct injury from blunt force trauma
We describe a case of an isolated thoracic duct injury resulting in the development of bilateral chylothorax following a motor vehicle collision in the absence of any other definable injury. We outline the initial patient presentation and diagnosis. After failing a trial of conservative management the patient underwent lymphangiography followed by thoracic duct ligation with pleurodesis. This case highlights the importance of recognizing thoracic duct injury following trauma. (Source: Journal of Radiology Case Reports)
