Enchondromas are the most common benign cartilaginous bone tumors of the toe. In contrast, chondrosarcomas are very uncommon in the foot. We report an unusual case of a chondrosarcoma arising in the great toe. The patient was a 62-year-old woman whose chief complaint was swelling of her left great toe. Radiography showed subtle punctate calcification and mild sclerosis and irregularity of the distal phalanx in the great toe. Magnetic resonance imaging showed extraskeletal growth. The distal phalanx was amputated. Histologic examination demonstrated a grade 1 chondrosarcoma. Two years after surgery, the patient was free of recurrence and lung metastasis.

AbstractArtificial intelligence (AI) holds the potential to revolutionize the field of radiology by increasing the efficiency and accuracy of both interpretive and noninterpretive tasks. We have only just begun to explore AI applications in the diagnostic evaluation of knee pathology. Experimental algorithms have already been developed that can assess the severity of knee osteoarthritis from radiographs, detect and classify cartilage lesions, meniscal tears, and ligament tears on magnetic resonance imaging, provide automatic quantitative assessment of tendon healing, detect fractures on radiographs, and predict those at highest risk for recurrent bone tumors. This article reviews and summarizes the most current literature.

Neuroretinitis from neurosyphilis is an uncommon finding in previously healthy young individuals. A 37-year-old presented with three days of painless, unilateral vision loss with an associated diffuse erythematous non-pruritic truncal rash. Physical exam demonstrated vision loss in the left eye. Fundoscopic exam showed unilateral peripapillary hemorrhage, papilledema and venous engorgement. Labs showed positive syphilis antibody qualitative. Magnetic resonance imaging demonstrated 12 millimeters of high right frontal lobe cerebrospinal fluid density. The patient was treated with benzylpenicillin and within 18 hours had improvement of his vision.

✓ The authors present an unusual case of intramedullary arachnoid cyst diagnosed in a patient after the lesion was resected. A wide decompressive surgery was performed and the lesion removed. Histopathological findings were consistent with the diagnosis of arachnoid cyst. Postoperatively the patient exhibited marked improvement in neurological status. To the best of the authors' knowledge, there is no case report of intramedullary arachnoid cyst reported in the literature. With the advent of newer neuroimaging modalities such as magnetic resonance imaging the number of cases of intramedullary arachnoid cysts encountered in the future may increase.

High Index Of Suspicion

Quadriceps tendon rupture usually occurs in adults and is rare in children. A six-year-old boy was playing at home and had a fall. He was unable to extend his right knee but there was no gap felt over the patella tendon or quadriceps. He was first seen by a family doctor and presented late to the surgeon three months after the injury. Radiographs and ultrasound were performed. The magnetic resonance imaging confirmed the findings of partial quadriceps tear. The patient was put in a cylinder case with the knee in extension for two months. Six months post-injury, he regained full range of motion without any complications. We present an unusual case of partial quadriceps tear in an otherwise healthy six-year-old boy that was treated successfully despite a delayed presentation. Besides a high index of suspicion, magnetic resonance imaging is a good modality to detect partial quadriceps tear in children.

ABSTRACTIntraosseous hemangioma is a rare bone tumor accounting for 0.7%–1.0% of all bone tumors. In the skull, frontal bone is the commonly involved bone. An 8-year-old female presented to our outpatient department with complaints of pain and swelling over forehead for 4 months. X-ray revealed a lytic expansile lesion involving frontal bone with sunburst pattern of bony spicules radiating to periphery of the lesion. Magnetic resonance imaging revealed the presence of a well-circumscribed lesion with both intra as well as extracranial components. Histopathology revealed a vascular tumor consisting of both small (capillary) and large (cavernous) sized vessels. A diagnosis of mixed type of hemangioma of the frontal bone was given. Recognition of hemangioma on radiology and confirmation by histopathology is essential for proper management as it might be confused clinically with other locally aggressive/malignant lesions.
