Septic arthritis of the wrist: A case of Parona space abscess in a rheumatoid arthritis patient with Charcot wrist.

Closed-space hand infections are considered an emergency requiring prompt management to avoid debilitating consequences and potential morbidity. Septic arthritis of the wrist is particularly uncommon in comparison to the large joints that are usually affected. We report a case of a 64-year-old female with known rheumatoid arthritis and neuropathic wrist, with superimposed septic arthritis of the wrist, complicated by abscess formation. Ultrasound and Magnetic resonance imaging revealed spread of infection to the midpalmar region and the space of Parona. Although collections in this space are extremely rare, if left untreated, they may lead to permanent disability. Incision and drainage of the abscess along with synovectomy of the affected wrist joint was performed. Streptococcus pneumoniae was the causative organism, despite the fact that Non-gonococcal and Staphylococcus aureus bacteria are the main causative agents of septic arthritis in adults.

Spontaneous Idiopathic Bilateral Sagittal Band Rupture: A Case Report.

Introduction: Extensor tendon subluxation or dislocation resulting from sagittal band rupture can be associated with snapping, catching, locking, pain, and swelling of the finger. Several etiologies were reported in the literature, with frequent mention of a traumatic rupture caused by a direct blow at the level of the metacarpophalangeal joint (MCPJ). The other causes of sagittal band injuries are degenerative disease, congenital infection, and rheumatoid arthritis. To our knowledge, we report the first case of spontaneous idiopathic bilateral sagittal band rupture. Case Report: We, herein, present the case of a seronegative 29-year-old female who presented with pain and swelling in the dominant hand for 4 days. Conclusion: Upon examination, she was found to have bilateral dislocation of the extensor tendons at the level of the (MCPJ) of the third and fourth digits. Any underlying cause was excluded, and the diagnosis was confirmed with a dynamic ultrasound study.

A case report: Osteomyelitis of the ischiopubic synchondrosis with abscess formation.

Osteomyelitis of the ischiopubic synchondrosis is an uncommon condition with high morbidity rates that present with nonspecific symptoms in the pediatric population. In this article, we report a case of a 10-year-old female who presented with right hip pain and fever following a trivial trauma. Laboratory tests revealed leukocytosis and elevated inflammatory markers. Despite negative blood culture and deceptively normal plain radiographs, magnetic resonance imaging demonstrated osteomyelitis of the ischiopubic synchondrosis with intra-osseous and intra-muscular abscess which was managed surgically by incision and drainage. We highlight the clinical importance of familiarity with such uncommon condition and the role of early magnetic resonance imaging in establishing the diagnosis to facilitate prompt surgical intervention.

A rare case of an intra-articular true lipoma of the ankle.

BACKGROUND: Most of the foot and ankle soft tissue tumors are benign. Although lipomas are the most common soft tissue tumors, intra-articular lipomas are an extremely rare entity. The majority of described cases of intra-articular lipomas occur in the knee joint. In particular, an intra-articular true lipoma of the ankle has not been reported. CASE PRESENTATION: We report the case of a 45-year-old woman who presented with a progressively growing ankle mass over 5 years, which started to restrict the range of motion. It was not preceded by any trauma or sports activity. On examination, a non-tender firm mass was evident on the lateral aspect of the right ankle joint with no signs of inflammation. It was non-compressible, non-mobile, and did not transilluminate. The clinical diagnosis was probable for a soft tissue ganglion. A radiograph revealed a soft tissue opacity over the anterolateral aspect of the tibiotalar joint. Magnetic resonance imaging (MRI) demonstrated a well-defined, multilobulated, encapsulated lesion located at the lateral aspect of the tibiotalar joint; with intra- and extra-articular components and an analogous signal intensity to fat. The patient underwent surgical excision of the tumor, and the histopathological examination showed mature adipose tissue representing an intra-articular lipoma. At the follow-up visit, the patient had complete resolution of symptoms and no active complaints. CONCLUSION: An intra-articular true lipoma of the ankle is an extremely rare tumor. MRI is an invaluable diagnostic tool to make a reliable diagnosis of intra-articular masses.
