Colloid cysts arise from the roof of the third ventricle and are at risk for obstructing the flow of cerebrospinal fluid (CSF) and causing increased intracranial pressure. With advancements and increased frequency of imaging, colloid cysts are sometimes discovered incidentally. In these cases, the neurosurgeon is faced with the decision of whether to intervene or manage conservatively.
A 67-year-old man was discovered to have a colloid cyst when imaging was performed for transient neurologic deficits. CT and MRI brain revealed a 5mm lesion in the third ventricle with characteristics suggestive of the colloid cyst. Except for his initial presentation, the patient did not exhibit any symptoms and was followed with serial imaging. Four years after discovery, the colloid cyst regressed in size.
The evolution and resolution of colloid cysts remain elusive; however, the discovery of incidental colloid cysts due to more frequent and more advanced neuroimaging emphasize the importance of this topic. The fear of conservative management is acute decompensation due to obstruction of CSF. However, surgical risks may be avoided if these asymptomatic lesions regress and resolve without intervention. Conservative management is a viable option for patients with colloid cysts, who may not only avoid surgery but who might also rarely experience cyst resolution.

It can be a cause of opportunistic infections of different organs, especially the lungs. Fungal mastitis is a rare infection in healthy subjects. It is seen in breastfeeding females and immunodeficient patients. We herein report a rare presentation of aspergilloma in a 73-year-old female who presented with a palpable mass in the breast. She was under medical control due to plasmocytoma. In ultrasound examination the lesion was classified as BI-RADS 4b and subsequently biopsy (fine needle and core needle aspiration) was performed. Biopsy provided immediate results and excluded breast cancer. In this rare case report of breast aspergillosis, we emphasize the role of pathology in medical diagnosis.Adenomyomatosis of the gallbladder is defined as hypertrophy of the gallbladder mucosal epithelium that invaginates into a thickened muscularis propria, leading to the formation of intramural diverticula. It is typically considered a benign condition most commonly affecting adults and, rarely, children. In this case report, we present a case of gallbladder adenomyomatosis in a 3-month-old infant. The diagnosis was made incidentally on ultrasound examination of the abdomen, in an otherwise asymptomatic child with no laboratory test abnormalities and no underlying disease. The purpose of this case report is to make infantile adenomyomatosis and its implications known to clinicians, as the literature on this topic is limited. To the best of our knowledge, this is the youngest reported case of adenomyomatosis in the pediatric population.Scleroderma is a rare, autoimmune, chronic condition that affects the connective tissue by excessive collagen production. If diagnosed before the age of 16, it is referred to as juvenile scleroderma. There are two major types of the condition localized and generalized scleroderma. Localized scleroderma has a much higher incidence than the generalized type which is extremely rare among children and affects mostly adults. In either case, imaging can prove to be useful in both the diagnosis and monitoring of the disease. In this article, we aim to review the imaging findings that can be present in juvenile scleroderma, focusing on ultrasonography, magnetic resonance imaging, and classic radiography. Ultrasound provides high-resolution images in real-time dynamic examination. With high-frequency transducers, it may provide a considerable input into the imaging of skin and musculoskeletal involvement. Several findings might be present when using B-mode or Doppler modalities such as thickening and hypervascularization of the cutis and subcutaneous tissue, synovitis and tenosynovitis, as well as small calcifications. Magnetic resonance imaging is also useful to evaluate inflammatory skin infiltration or skin atrophy, as well as deeply located structures, including fasciae, muscles and joints that might not be seen on ultrasonography. This modality is, however, expensive and time-consuming, and might require sedition in children. Classic radiology can show soft tissue calcifications, acroosteolysis, contractures, and subluxations. Computed tomography, which requires a high dose of radiation, is generally avoided in children, except in very specific cases.Aim of the study Ultrasonographic examination of intraosseous jaw pathologies may reveal interesting incidental, mobile hyperechoic particles (“snowflakes”) in anechoic areas. Purpose of this study is to explain and discuss this snowing-like ultrasonographic feature of intraosseous jaw pathologies. Material and methods This study included 113 patients admitted to our clinic for examination 43 (38.05%) males and 70 (61.9%) females with a mean age of 34.9 ± 17.2 years (range 6-72 years). A total of 120 intraosseous lesions were evaluated prior to surgery using ultrasonography; these included non-neoplastic, odontogenic, and non-odontogenic lesions. Results In total, 5 (4.1%) of the 120 lesions exhibited snowing-like feature on ultrasonography, including 2 (1.6% of total) of 3 incisive canal cysts, 2 (1.6% of total) of 7 dentigerous cysts, and 1 (0.8% of total) of 19 odontogenic keratocysts. Conclusions Snowflakes evident on ultrasonography of intraosseous jaw lesions may be specific to certain pathologies. selleck kinase inhibitor Future studies correlating radiologic and pathologic features of intraosseous jaw lesions should focus on ultrasonographic snowing-like appearance in different types of lesions and explore why they occur.
