Intramuscular Dissecting Baker's Cysts: A Case Series Highlighting Ultrasound Diagnosis and Differential Considerations.

Baker's cysts, commonly incidental findings, can occasionally present as intramuscular dissecting cysts within the medial gastrocnemius muscle. This case report highlights the ultrasound features and differential diagnoses of intramuscular dissecting Baker's cysts through the examination of three distinct cases: a 64-year-old woman with severe osteoarthritis, an 80-year-old man with a palpable mass in the popliteal fossa, and a 37-year-old man with early degenerative arthropathy. Each case was investigated using ultrasound, revealing fusiform hypoechoic fluid collections with heterogeneous echostructure parallel to the medial gastrocnemius muscle bundle and lacking posterior reinforcement. The clinical context and ultrasound findings were critical in differentiating these cases from other conditions, such as superficial thrombophlebitis, intramuscular seroma, and intramuscular myxoma. These cases emphasize the role of ultrasound in diagnosing intramuscular dissecting Baker's cysts. Accurate diagnosis requires careful consideration of ultrasound features in conjunction with clinical findings.

Aggressive Giant Cell Tumor of the Scapula in a 35-Year-Old Woman.

Giant cell tumors (GCTs) are a category of benign but locally aggressive tumors that are challenging to treat. GCT topography most often affects the epiphyseal and metaphyseal regions of long bones but rarely flat bones. We report the case of a 35-year-old woman with an aggressive GCT of the right scapula. Unfortunately, the late presentation of this case to the emergency department makes the scapulectomy more difficult to carry out effectively. As this case highlights, the lack of access to primary care and the lack of available family physicians in the community remains detrimental to good medical care in systems with limited resources.

Osteogenesis Imperfecta Type 3 in a 10-Year-Old Child With Acute Respiratory Distress Syndrome.

Osteogenesis imperfecta (OI) represents a group of rare connective tissue disorders characterized by excessive bone fragility. Type 3 is a rare form with new mutations; osteopenia and bone fragility are significant with numerous fractures, continuous and severe deformity of the spine, and long bones. Our case study concerns a 10-year-old male child admitted to the pediatric department of the State University of Haiti Hospital. OI type 3 was diagnosed based on both clinical and radiological assessments. Multidisciplinary care was initiated. Although the evolution was still unsatisfactory, characterized by intermittent episodes of dyspnea and left lung hypoplasia, he was stabilized after 28 days of hospitalization and referred to the orthopedics department for follow-up care.
