Bilateral Kohler's Disease: A Case Report.

Kohler's disease is characterized by osteochondritis of the navicular bone due to various factors like the lack of blood supply and late ossification of the bone. In particular, it is a disease of the pediatric age group, which has male preponderance. It may present with bony pain unilaterally or, at times, be asymptomatic and diagnosed accidentally. Clinical presentation and radiological investigations are the mainstay of diagnosis. This self-limiting condition requires only symptomatic conservative management. A surgical approach is not yet indicated. One such case of bilateral Kohler's disease is presented in this report. Here, we discuss the disease's presentation, examination, treatment, and prognosis.

Aneurysmal Bone Cyst of the Head of the Fibula: An Unusual Presentation.

Bone cysts are tumor-like lesions of bone. These are primarily of two types: simple or unicameral and aneurysmal bone cysts (ABC). An aneurysmal bone cyst (ABC) is a blood-filled cyst that usually occurs over the metaphysis of long bones, flat bones, and vertebrae. The symptoms of these cysts include pain and swelling over the area. It may consist of pathological fractures as well. The cyst is benign but may invade local tissue and erode bone. The investigations required are radiological and histopathological examinations that further confirm the diagnosis. The differential diagnosis includes giant cell tumor and telangiectatic osteosarcoma. Here, we discuss a case of an aneurysmal bone cyst of the head of the fibula, which is a rare site for ABC to occur (common sites are metaphyseal ends of the femur, humerus, tibia, scapula, and vertebrae). The treatment modalities have a wide range of options that range from en bloc resection to minimally invasive techniques such as selective artery embolization, sclerotherapy, and radiotherapy.

Thoracolumbar Extramedullary Myxopapillary Ependymoma: A Rare Case.

An intradural extramedullary myxopapillary ependymoma is a rare spinal cord tumor found in the thoracolumbar region of the spine. In this case report, we describe this case and review the various aspects of ependymomas. There are different types of ependymomas based on their location and histopathological appearance. Myxopapillary ependymoma is a non-invasive, slow-growing benign tumor that can present as a simple complaint of lower back pain to a severe stage like paraplegia.
