Deep cerebral venous thrombosis mimicking influenza-associated acute necrotizing encephalopathy: a case report
Abstract Background Acute necrotizing encephalopathy is one of the most devastating neurological complications of influenza virus infection. Acute necrotizing encephalopathy preferentially affects the thalamus bilaterally, as does deep cerebral venous thrombosis, which can lead to misdiagnosis. Case presentation A 52-year-old Japanese woman infected with seasonal influenza B virus presented to the emergency care unit in our hospital with progressive alteration of her level of consciousness. Bilateral thalamic lesions were demonstrated by magnetic resonance imaging, leading to a tentative diagnosis of acute necrotizing encephalopathy. However, she had deep cerebral venous thrombosis, and the presence of diminished signal and enlargement of deep cerebral veins on T2*-weighted imaging contributed to a revised diagnosis of deep cerebral venous thrombosis. Anticoagulant therapy was initiated, leading to her gradual recovery, with recanalization of the deep venous system and straight sinus. Conclusions To the best of our knowledge, these results represent the first report of deep cerebral venous thrombosis associated with influenza infection. It is clinically important to recognize that deep cerebral venous thrombosis, although rare, might be one of the neurological complications of influenza infection. In the presence of bilateral thalamic lesions in patients with influenza infection, deep cerebral venous thrombosis should be considered in addition to acute necrotizing encephalopathy. Delays in diagnosis and commencement of anticoagulant therapy can lead to unfavorable outcomes
Parenchymal renal rupture due to an obstructive ureteric calculus in an incompletely duplicated renal pelvis and ureter
Introduction Parenchymal renal rupture due to a ureteric calculus is extremely rare and an emergency. Case presentation A 54âyearâold man was brought to the emergency room with left back pain without trauma. Computed tomography showed left parenchymal renal rupture with an incompletely duplicated renal pelvis, ureter, and an 11âmm ureteric calculus in the ureterovesical junction. A ureteral stent was placed, and the patient was treated conservatively as his vital signs were stable. We performed transurethral lithotripsy after resolution of the perirenal hematoma. Conclusion To best of our knowledge, this report is the first to present a case of parenchymal renal rupture due to a ureteric calculus in an incompletely duplicated renal pelvis and ureter. Ureteric calculus within an incompletely duplicated renal pelvis and ureter is at risk of parenchymal renal rupture. Therefore, the aggressive treatment of ureteric calculus could be important
A case of midâureteral stricture with ipsilateral atrophic kidney in a young adult
Introduction Most congenital ureteral strictures occur at the ureteropelvic or ureterovesical junction in children. Midâureteral stricture is very rare and can cause congenital hydronephrosis. Only a few studies have reported on coexisting midâureteral stricture with ipsilateral atrophic kidney in young adults. Case presentation A 16âyearâold girl presented with repeated urinary tract infection. Computed tomography revealed a right atrophic kidney and hydroureter. Retrograde pyelography showed a midâureteral stricture. Laparoscopic nephroureterectomy was performed, and histological examination revealed midâureteral stricture with hyperplasia of the fibrous connective tissue and an atrophic kidney. Conclusion Midâureteral stricture in a young adult is extremely rare. Appropriate imaging studies including retrograde pyelography are necessary for accurate diagnosis of midâureteral stricture
Two cases of pelvic hematoma after prostatic urethral lift surgery
Introduction There are few reports of pelvic hematoma after prostatic urethral lift. Here, we report two cases of pelvic hematoma in Japan. Case presentation The first case was a 71âyearâold man with benign prostatic hyperplasia who underwent prostatic urethral lift. Although the procedure was uneventful, he experienced lower abdominal pain the day after the operation. CT revealed a hematoma in the right pelvis; however, it was manageable with conservative treatment. The second case was a 68âyearâold man. The procedure was uneventful; however, 6âdays after the operation, a subcutaneous hematoma appeared in the lower abdomen. CT revealed a hematoma in the left pelvis. We then performed pelvic hematoma removal surgery. Conclusions Pelvic hematomas after PUL may requires attention, particularly in men with the narrow pelvises. Appropriate compression of the prostate and a high lithotomy position procedure could effectively avoid the occurrence of pelvic hematomas
