RESUMO
A 48-year-old gentleman presented to the ophthalmology department with progressive monocular vision loss, a relative afferent-pupillary defect, decreased color perception, headache, proptosis, and retro-orbital pain. This particular patient's demographics and disease course did not suggest a "typical" retro-bulbar optic neuritis and highlights the importance of avoiding presumptive steroid treatment in such "atypical" cases. Further investigations revealed a compressive optic neuropathy secondary to an orbital tumor (B-cell non-Hodgkin's lymphoma) and were subsequently treated by a multi-disciplinary approach. Early detection and commencement of treatment is a crucial determining factor in orbital lymphoma prognosis and is therefore an important differential diagnosis for an ophthalmologist to consider when evaluating patients with "atypical" optic neuropathies.
RESUMO
Primary synovial chondromatosis is a rare benign neoplastic process, in which cartilaginous nodules are produced in the subsynovial tissue. It has 3 main subtypes (intra-articular, tenosynovial and bursal). We present the case of a 61-year-old female, with a mass involving her right thumb for at least 5 years, which had recently increased in size. X-ray showed a soft tissue mass, without calcification or any underlying bony abnormality. Ultrasound and MRI showed a 6-cm mass surrounding the right flexor pollicis longus tendon of the right thumb. The patient went on to have surgical resection and was given a diagnosis of tenosynovial chondromatosis.
