Popliteal cysts, or Baker cysts, are considered rare in children and may exhibit particular features, as compared with adults. We studied data from 80 paediatric patients with 55 Baker cysts, examined over a period of 7 years, and correlated clinical presentation with findings on ultrasonography and MRI. Prevalence of popliteal cysts was 57% in arthritic knees, 58% with hypermobility syndrome, ...

Intramedullary spinal epidermoid cysts are benign ectopic embryological growths with reported incidence of less than 1% of intramedullary tumors. In this case we report an unusual cervical intramedullary epidermid with liquid contents. A 40-year-old patient presented with progressive weakness of all four limbs of four months duration, bowel and bladder disturbances of two days duration, pain an...

Background: Spinal extradural arachnoid cyst is extremely rare. The longest SEACs that have been reported in previous studies involved no more than 5 spinal segments. This study presents a case of SEAC diagnosed from T9 to L4 and excised through a novel laminectomy/laminoplasty. Case presentation: A 22-year-old female presented with a 5-year history of progressive paraparesis and numbness in bo...

BACKGROUND Intraosseous arachnoid cysts are rare and difficult to diagnose. The purpose of this study was to describe the clinical and radiological semiology of petrous and sphenoid arachnoid cysts and to propose a specific management strategy. METHODS This was a retrospective, descriptive study of patients with arachnoid cysts, which utilized CT, MRI, and the patients' medical histories. R...

BACKGROUND This paper describes MRI findings of upper cervical subluxation due to alar ligament disruption following a vehicular collision. Incidental findings included the presence of a myodural bridge and a spinal cord syrinx. Chiropractic management of the patient is discussed. CASE PRESENTATION A 21-year old female presented with complaints of acute, debilitating upper neck pain with unre...

BACKGROUND Chronic intradiploic hematoma was first described by Chorbski and Davis in 1934. To date, only twelve cases have been reported in the literature. Chronic intradiploic hematomas have also been described as non-neoplastic cysts of the diploe, traumatic cysts, and giant cell repetitive granulomas. The term chronic intradiploic hematoma was coined by Sato et al. in 1994. CASE DESCRIPTI...

. Mediastinal cystic formations are well-shaped, often round that contain fluid and lined with epithelium. The main include congenital benign cysts (bronchogenic, duplicating the esophagus, neuroenteric, pericardial thymic cysts), meningocele, mature teratomas lymphangiomas. Many tumors (e.g., thymomas, Hodgkin's disease, germ cell tumors, mediastinal carcinomas, lymph node metastases, nerve ro...

A 73-year-old woman had progressive apathy, forgetfulness, and gait disturbance for 6 months. Neurologic examination showed inattentiveness, memory impairment, and broad-based gait. Noncontrast MRI was performed due to gadolinium allergy. MRI and contrast-enhanced CT scan revealed symmetric bilateral frontal cysts (figure 1A) and an anterior skull base nodule (figure 1, B and C). Surgery confir...

PURPOSE The purpose of this study is to identify the role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the classification of liver hydatid cysts (HCs) and their differentiation from simple cysts and liver abscesses. MATERIALS AND METHODS Twenty-two patients that were sent to our department with preliminary diagnoses of HCs or abscess were included in the study. Thirty lesions ...
