Nutcracker syndrome is a rare entity that corresponds to an abdominal pain following compression of the left renal vein during its passage between the aorta and the superior mesenteric artery, with a peak prevalence in adults between 20 and 30 years old, The typical clinical presentation includes hematuria, orthostatic proteinuria with or without flank pain. doppler ultrasound has a sensitivity of 78% and specificity of 100%, Both CT and MRI can show the compression of the left renal vein between the aorta and the superior mesenteric artery. We report the case of a young patient admitted to the emergency room for abdominal pain mainly localized in the left hypochondrium, with microscopic hematuria, a CT scan was performed showing a reduced aorto mesenteric angle with a compression of the left renal vein and collateralization of venous circulation of left gonadal vein.
Retrorectal tumors are rare diseases and they can be challenging to diagnose and to manage. Usually they have a slow growth and they are asymptomatic. When present, symptoms depends on the dimensions of the tumor and their position. Inside the retrorectal space may develope a wide variety of benign and malignant masses.
A 70-years-old, obese, female patient was admitted to our hospital referring pelvic and lower-back pain for six months. The retrorectal mass was incidentally detected on imaging, and treated with a modified Kraske procedure.
Pathological examination revealed a rare retrorectal epidermoid cyst. We also reviewed the informations present in the scientific literature about the incidence, diagnosis and treatment options of retrorectal tumors.
Even though the rarity and heterogeneity of these tumors, we agree with literature that their surgical management is mandatory in order to achieve a definitive diagnosis and to avoid complications including malignant transformation. The surgical approach should be tailored for each patient and according to tumor's features.

On presentation, the patient had severe stridor and tachypnea, with oxygen saturation less than 60%. As the patient presented alone to the ER, obtaining any history was not possible. Chest x-ray showed a huge right paratracheal mediastinal mass compressing the airway. The patient was not able to lie supine and was taken to the OR for intubation under fiberoptic bronchoscopy guidance. Bronchoscopic evaluation showed significant compression of the trachea from the right side. A small endotracheal tube (size 5) was successfully inserted. Then, the patient was taken for a chest CT with IV contrast. Chest CT showed a huge vascular mass compressing the trachea, the right mainstem bronchus, and the superior vena cava. The study showed the proximal innominate artery, followed by a pseudoaneurysm. There was an interruption of the right subclavian artery at its origin. Collaterals were seen supplying the right upper limb. Surgical resection was done. Postoperatively the patient gave a history of chest-penetrating injury in the right infraclavicular area, 15 years prior to presentation. The pseudoaneurysm of the innominate artery is a rare delayed complication of chest trauma.
Accelerated femoral head avascular necrosis after a single dose intra-articular steroid injection is a rare pathology. Few cases were reported in the literature. find more Most cases were managed with total hip arthroplasty.
In this study, we report two rare cases of destructive osteonecrosis of the femoral head. Both patients presented with hip osteoarthritis that failed nonoperative measures. A single intra-articular corticosteroid injection was administered for each patient. Both patients had femoral head destruction and significant resorption at 14 and 11 weeks, respectively. Septic arthritis was ruled out by blood tests and joint aspiration. Total hip arthroplasty (THA) was undertaken and histology reports confirmed the osteonecrosis. The postoperative follow-up was uneventful with satisfactory hip function.
Destructive osteonecrosis of the femoral head is a rare catastrophic potential complication of intra-articular corticosteroid injection. Hence, physicians must consider this complication when counseling patients before an intra-articular corticosteroid hip injection.

Localised amyloidosis of the urinary tract is rare and often presents with haematuria.
A 59 year old male presented with recurrent episodes of frank haematuria exacerbated by anticoagulation after a minor stroke. He had a background of hypertension, hypercholesterolaemia, and Parkinson's disease. Initial investigations did not reveal a cause, but eventual cystoscopic biopsy showed bladder mucosa expanded by deposits of amorphous, pale, eosinophilic, proteinaceous material and immunohistochemical staining revealed the presence of amyloid deposition. Workup for systemic amyloidosis was negative. A diagnosis of primary localised amyloidosis of the bladder was made. Trans-urethral resection was performed and annual cystoscopic surveillance was commenced. He was followed up for 11 years without recurrence.
A comprehensive literature review revealed 349 published cases of localised amyloidosis of the urinary tract, with a median age of 57 (interquartile range 49-69), and a male preponderance (1.5 to 1). Painless visible haematuria (65%) was the most frequent presenting complaint and the bladder was the most common site of involvement (71%). Transurethral resection was the most common form of management (42%) but a proportion of patients underwent more radical surgery (nephroureterectomy/nephrectomy 9%, cystectomy 1%). Median follow up was 33 months (interquartile range 12-108) and 35% of patients had recurrent disease. This patient represents a typical case of localised amyloidosis of the urinary tract.
This is the most up to date review of the literature describing localised amyloidosis of the urinary tract. The disease is rare, but salient to the urologist as it invariably mimics urinary tract malignancy.
