■二水合焦磷酸钙(CPPD)疾病,也被称为焦磷酸盐关节病或假性痛风,定义为关节软骨内的CPPD沉积。它于1962年首次描述。发生CPPD疾病的代表性部位包括最常见的膝关节,然后是腕关节.关节肿胀和疼痛是最常见的临床表现,典型的鉴别诊断是退行性关节炎。微观上,当在偏振光下检查时,样品显示出许多正双折射菱形晶体。
■我们介绍了一名70岁的女性,患有右侧疼痛性坐骨神经痛,并伴有患肢酸痛和笨拙。她的最终诊断是不寻常的腰椎硬膜外肿瘤假性疼痛,值得注意。椎板切除术后切除肿瘤CPPD沉积。随后,她的症状在术后减轻,无需更多镇痛药.她的神经功能得到了适当的恢复。
■这是一份罕见的报告,用于在不熟悉的腰椎硬膜外位置提供假性活动,这是一个意想不到的诊断。对于临床医生来说,对正在进行的疾病实体进行精确的初步诊断可能很困难,因为这种病理的临床表现与其他常见的退行性腰椎疾病相似。
UNASSIGNED: Calcium pyrophosphate dihydrate (CPPD) disease, also known as pyrophosphate arthropathy or pseudogout, is defined as CPPD deposition within the articular cartilage. It was first described in 1962. The representative locations where CPPD disease occurs include the most common knee joint, followed by the wrist joint. Joint swelling and pain are the most common clinical presentations, and the typical differential diagnosis is degenerative arthritis. Microscopically, the specimen demonstrates numerous positively birefringent rhomboid shaped crystals when examined under polarized light.
UNASSIGNED: We present a 70-year-old female with right painful sciatica accompanied by coexisting affected limb soreness and clumsiness. Her final diagnosis was unusual lumbar extradural tumoral pseudogout that was worth noticing. Tumoral CPPD deposition was excised after laminectomy. Subsequently, her symptoms were abated postoperatively without a need for more analgesics. Her neurological function was properly recovered.
UNASSIGNED: This is a rare report to proffer pseudogout in an unfamiliar lumbar extradural location, which is an unexpected diagnosis. Making a precise tentative diagnosis for the ongoing disease entity might be difficult for the clinicians because the clinical manifestations of this pathology are similar to those of other common degenerative lumbar spinal diseases.
