Mycotic Pulmonary Artery Aneurysm a Rare Complication of Ventricular Septal Defect With Infective Endocarditis: A Case Report.

Introduction: Pulmonary artery aneurysms encompass a wide range of presentations and forms. Mycotic aneurysms represent a particular subset of focal dilatation of the vessel wall with high morbidity and mortality rates. Herein, we report the case of a 32 year old patient, with a prior history of ventricular septal defect presenting with a mycotic pulmonary artery aneurysm associated with infective endocarditis and septic emboli. Case presentation: We present the case of a 32 year old male with known history of congenital ventricular septal defect presented to the emergency department with signs of sepsis and dyspnea. Blood cultures were positive for methicillin-sensitive Staphylococcus aureus. An echocardiogram found evidence of endocarditis with multiples intra cavitary vegetations. A CT angiogram demonstrated major right ventricular dilatation, multiple nodules and peripheral opacities, scattered throughout the lungs, indicative of septic emboli. Segmental saccular dilatation of the left lateral basal pulmonary artery consistent with a mycotic aneurysm formation was found. The patient was started on intravenous antibiotics and given the overall satisfactory evolution a conservative approach was pursued. The patient was discharged with antibiotics and scheduled for surgical repair of the ventricular septal defect. Conclusion: To our knowledge, mycotic aneurysms associated to congenital heart malformation like ventricular septal wall defect remains a rare condition with few reported cases in the literature. Being aware of this entity is important for every practicing radiologist to allow for early diagnosis and treatment.

Sigmoid diverticulitis mimicking a urinary bladder tumor: A rare case report.

Urothelial cell carcinomas represent the vast majority of urinary bladder tumors. However, many inflammatory and non-neoplastic conditions can mimic a urinary bladder malignancy. In that matter, diverticulitis can progress into colovesical fistula formation with a bladder wall abscess that can mimic a pseudo mass. Nonetheless, the presence of a bladder wall mass, usually requires pathologic examination. We report the case of a 60 year old woman with recurrent urinary infections due to a focal bladder mass revealing a colovesical fistula as a complication of sigmoid diverticulitis.

Chronic abdominal pain revealing a gastrointestinal stromal tumor.

Gastrointestinal stromal tumors (GIST) are mesenchymal neoplasms most frequently seen in the stomach and small intestine, arising in the muscularis propria of the intestinal wall. Given its nonspecific clinical presentation, it can represent a diagnostic challenge, especially in abdominopelvic locations. Lesion evaluation of abdominopelvic tumors can be difficult and lead to misinterpretation in assessing their origin. We report the case of an 84-year-old woman with a voluminous small bowel GIST mimicking a uterine neoplasm.

Adrenal Abscess in a Chronic Hemodialysis Patient: A Case Report.

Adrenal gland abscesses are rare lesions usually reported to be caused by fungal pathogens and typically through hematogenous spread from other primary sources of infection. Imaging has always been known to play a major role in the characterization of focal adrenal lesions. However, given the rare occurrence of abscesses in this location, making the right diagnosis remains challenging. We report the case of a 39-year-old man with chronic renal disease on hemodialysis presenting with signs of sepsis and left upper quadrant pain revealing a left adrenal gland abscess.

Ollier disease: A case report and literature review.

Ollier disease is an uncommon disease characterized by several enchondromas and an asymmetric distribution of cartilage lesions, which can vary significantly in size, location, age, and gender. The primary symptom of this condition is a nonossifying chondrocyte mass or hamartomatous chondrocyte growth in the metaphysis of a short or long bone. Specific cases can progress to chondrosarcoma or osteosarcoma. X-ray is the most fundamental diagnostic technique for skeletal illnesses. In this article, we present a case of Ollier disease from Mother and Child Hospital IBN SINA, Rabat, Morocco.

A rare case: Spontaneous gastric fistula from a hydatid cyst of the liver.

The hydatid cyst is a worldwide anthropozoonosis, which constitutes a health issue in Northern Africa. It may involve any organ, but it mostly affects the liver. This often asymptomatic disease can lead to multiple complications. Among them, spontaneous fistulization of a hepatic hydatid cyst in the stomach is exceptional even in endemic countries. We report the case of a 38-year-old female with febrile biliary colics due to a hydatid cyst of the liver fistulized in the stomach. The diagnosis was established based upon different clinical, biological and mainly radiological features. She received surgical treatment with satisfactory postoperative outcome.

Diffuse malignant peritoneal mesothelioma mimicking ovarian cancer.

Diffuse malignant peritoneal mesothelioma (DMPM) and peritoneal carcinomatosis have similar computed tomography imaging features. Peritoneal carcinomatosis is a known metastatic site for many malignancies and particularly gastrointestinal tract and ovarian cancers. Also, DMPM can masquerade as an ovarian epithelial neoplasm, with very similar clinical presentation and an overlap in imaging findings. When no evident primary tumor is detected other than the peritoneal disease, primary malignant mesothelioma should be considered. Since accurate diagnosis is essential for treatment management, the gold standard in differentiating between these two entities lies in histological analysis. We report a case of DMPM that was initially misdiagnosed as an ovarian cancer, where the biopsy of a peritoneal nodule was able to correct and confirm the diagnosis of DMPM.

Nutcracker syndrome: A rare cause of chronic pelvic pain and left back pain.

The Nutcracker Syndrome is a rare and often unrecognized cause of chronic pelvic pain and left back pain. These symptoms are due to the left renal vein compression between the aorta and the superior mesenteric artery (anterior nutcracker) or between the aorta and the spine (posterior nutcracker). The variety of clinical manifestations make the diagnosis difficult and commonly delayed. Therefore, imaging plays a key role in correcting the diagnosis by confirming the left renal vein stenosis and ruling out any differential diagnosis. Treatment options are discussed by a multidisciplinary team involving urologists, nephrologists and vascular surgeons for each patient. We report the case of 2 patients presenting chronic pelvic and lower back pain in whom clinical investigation and CT imaging findings were consistent with a nutcracker syndrome.
