Renal agenesis associated with contralateral ectopic ureter and hydroureteronephrosis.

Congenital anomalies of the kidney and the urinary tract such as renal agenesis and ectopic ureter have complex development. These anomalies have variable presentations and associations. In this report, we highlight the case of a young man with congenital renal agenesis presenting for a urinary tract infection. Abdominal and pelvic computed tomography imaging revealed the rare association of renal agenesis with contralateral ectopic ureter and subsequent hydroureteronephrosis. A urinary tract infection can be the presenting complication of such association, and a long follow-up is needed to anticipate the management.

Incidentally detected Non-Hodgkin's lymphoma of the breast. A case report with review of literature.

We report a case of primary breast lymphoma which was incidentally detected in a 71 year-old-female while investigating for pulmonary embolism with Computed tomography angiograph (CTA) of the chest. Primary breast lymphoma has no specific imaging features however may have better prognosis than breast carcinoma and management is non-surgical.

Abdominal aortic aneurysm and its association with duodenal obstruction: aortoduodenal syndrome.

Proximal small bowel obstruction in the region of the duodenum is an uncommon clinical entity. Our case, which involves obstruction of the third portion of the duodenum due to an abdominal aortic aneurysm (AAA), is even more unusual. A review of the relevant literature regarding duodenal obstruction due to extrinsic compression includes features that differentiate aortoduodenal syndrome from superior mesenteric artery syndrome. Management of these conditions range from conservative to surgical, of which now includes a more recent role of metallic stents in some instances.

Incidentally discovered type 1 split cord malformation in an adult patient.

Split spinal cord syndrome (SCM), an entity of spinal dysraphisms, occurs rarely in adults and is associated with tethered cord syndrome, which commonly presents with back pain. Besides clinical findings, neuroimaging by Magnetic resonance imaging or computed tomography is needed for diagnosis. We report a case of a previously healthy 51-year-old man who presented for right upper abdominal quadrant pain. A computed tomography scan of the abdomen and pelvis incidentally discovered the diagnosis of type 1 SCM. This case highlights that SCM can remain asymptomatic throughout life to be diagnosed at one point by neuroimaging. Whenever no clinical complications exist, no surgical intervention might be indicated.

Trans-urethral resection of bladder tumor (TURBT) and radiofrequency ablation of renal tumor: Rare etiologies of chyluria.

Chyluria is a rare entity which is caused by abnormal communication between the lymphatic system and the urinary tract, which allows the passage of chyle into the urine. Whenever symptomatic, chyluria presents with lower urinary tract symptoms such as dysuria and hematuria. Multiple imaging modalities can aid in diagnosis such as lymphoscintigraphy, retrograde pyelography, CT scan of the abdomen and pelvis, and magnetic resonance imaging. Numerous etiologies are associated with chyluria among which are surgical interventions. Partial and radical nephrectomy have been reported in a number of symptomatic and asymptomatic cases, while radiofrequency ablation of renal tumors has been very rarely reported. Herein, we report 2 cases of chyluria; one caused by trans-urethral resection of a bladder tumor and another by radiofrequency ablation of a renal oncocytoma. Fat-fluid level in the urinary bladder was seen on both precontrast and postcontrast images of CT scan of the abdomen and pelvis. Cystoscopy demonstrated no evidence of any abnormality of the urinary bladder.

Solid pseudopapillary Tumor of the Pancreas: Radiological and surgical review.

Solid Pseudopapillary Neoplasms of the pancreas are rare pancreatic tumors with low-grade malignant potential, typically affecting young females. In this review, we discuss the surgical anatomy; the imaging characteristics, and image reporting essentials for proper surgical planning along with the atypical features which should caution the physician regarding the risk of malignancy. We also discuss the common surgical procedures and organ preservation surgeries along with a comprehensive review of the literature.

An unresponsive COVID-19 patient.

Neurological manifestations and complications are increasingly reported in coronavirus disease-19 (COVID-19) patients. Although pulmonary manifestations are more common, patients with severe disease may present with neurological symptoms such as in our case. We describe a case report of a 50-year-old male without previous known comorbidity who was found unresponsive due to COVID-19-related neurological complications. During this pandemic, an emergency radiologist should be well acquainted with various neurological manifestations of COVID-19. In this article, we will discuss the pathogenesis, imaging findings, and differentials of this disease.

Foot and Ankle Hepatocellular Carcinoma Metastasis.

Bone is the third most common site of metastasis from hepatocellular carcinoma (HCC), the first two being the lung and lymph nodes, respectively. Metastatic HCC has been reported in the vertebrae, ribs, pelvis, and femur, which are more common sites of bone metastases. We present a case of HCC with metastasis to the distal tibia, fibula, and small bones of the feet as the only sites of bone metastasis, along with a brief literature review.
