Rare Case of Primary Posterior Mediastinal Hydatid Cyst with False Aortic Aneurysm

Hydatid cystic disease caused by the parasite Echinococcus granulosus is one of the major health problems in underdeveloped countries. Mediastinal localization is very rare. We report a rare case of hydatid disease in the posterior mediastinum with an enormous aorta defect. The patient underwent vascular graft placement without shunting or bypass.

Bovine Arch

A 24-year-old man presented with rapidly progressive dyspnea due to mixed aortic stenosis and insufficiency. Unicommissural unicuspid aortic valve, ascending aortic aneurysm, and a bovine arch were identified on computed tomography angiography. Uncomplicated surgical mechanical valve replacement and ascending aortic graft placement improved his symptoms. Aortopathy is common in unicuspid valve patients.

Magnetic Resonance Scanning

Incidental extracardiac findings (ECFs) are commonly noted on cardiac imaging. The majority of the ECFs are noticed on computed tomography (CT), cardiac magnetic resonance scanning, and myocardial perfusion imaging. Although transthoracic echocardiography (TTE) is a widely used cardiac modality, there is scarcity of data describing ECF on TTE. ECFs have the potential to alter patient management. We present a rare case of a cystic mass seen in the posterior mediastinum on TTE, which led to further evaluation and diagnosis of esophagitis with ulceration.

Mediastinal Seminoma

We report an atypical case of posterior mediastinal seminoma. Mediastinal seminomasare a rare form of tumor usually located in the anterior mediastinum. Our casepresented as a diagnostic challenge because of the difficulty of differentiating the primarymediastinal mass from a primary lung neoplasm. Our case highlights the fact thatseminomas may occur in the posterior mediastinum and the importance of consideringa broad differential diagnosis, especially in cases of poorly differentiated carcinoma ofthe mediastinum.

Pouch Of Douglas

Abstract Hydatid cyst is a zoonotic infection and a significant public health problem in low- and middle-income countries. A 79-year-old female patient was presented to the gynecology outpatient department with complaints of pain in the abdomen and difficulty in micturition, with a mass palpable per speculum. The ultrasound was suggestive of an ovarian cystadenocarcinoma, whereas computed tomography of the abdomen favored hydatid cyst with adnexal neoplasm as a differential diagnosis. Considering the contradictory findings, a frozen section was sent to confirm the diagnosis, which showed hooklets of Echinococcus granulosus/hydatid cyst under the microscope. This was a rare case of pelvic hydatid cyst mimicking ovarian malignancy and was associated with a less-preferred mode of investigation (frozen section). This article focuses on how a frozen section, despite its limitations and being expensive, can still be considered for accurate patient management.

Renal Malignancies

Localized Cystic Disease of the Kidney (LCDK) is an extremely rare benign disease in pediatric population. Although its management is conservative and generally requires no treatment, the unfamiliarity with the disease can expose such patients to misdiagnosis as renal malignancies or uncertainty for proper treatment. We report such a case in an infant and review the current literature.

Abstract Background Neurofibromatosis comprises neurofibromatosis type 1 (NF1) and type 2 (NF2). Major tumor type of NF1 are neurofibroma recognized as benign peripheral nerve tumor, malignant peripheral nerve sheath tumor (MPNST), and glioma. Case presentation We report a woman with a special condition, whose tumors in body surfaces were benign neurofibroma and tumors in posterior mediastinum are MPNST. The chest-enhanced CT suggested a round soft tissue density in posteriormediastium. The diagnosis was established by pathology and immunohistochemistry. A single-stage thoracoscopic mediastinal mass resection was performed. The whole operation went smoothly and the CT scan of lungs did not show relapse of tumor three months later. Conclusions The appearance of neurofibroma should draw particular attention to the possibility of developing MPNST. More careful imaging examinations should be carried out, and pathological examination could diagnose it.

Indirect Hemagglutination Test

We present a patient with symptoms of abdominal pain and frequent urination due to a huge mass in the retrovesical region. All imaging modalities revealed a cystic mass containing small daughter cysts located between the urinary bladder and rectum. Its characteristics led us to suspect the presence of a hydatid cyst, and an indirect hemagglutination test for Echinococcus granulosus was found positive. No other involvement of hydatid cystic disease was detected. The primary site for the hydatid disease was therefore regarded as the pelvis, on which only a few cases have been reported previously. The patient started albendazole therapy, but refused operation. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions of the world.
