2024年11月26日 · CT. CT is far superior in detecting intralesional fat and calcification. The reported prevalence of calcification in hamartomas on CT varies from 5 to 50%, while fat may be identified in up to 60% of hamartomas at CT. The fat components may be localized or generalized within the nodule.

Contrast CT revealed a lobulated >2 cm size lesion with central and eccentric popcorn calcification within suggestive of a benign etiology like pulmonary hamartoma. A pulmonary hamartoma is a benign neoplasm composed of normal but disorganized lung tissues, with variable components of cartilage, connective tissue, muscle, fat, and bone.

2019年7月21日 · Pulmonary hamartoma: characteristic radiographic and CT findings. (A) Composite image of posteroanterior (left) and lateral (right) chest radiographs show a well-defined, 5-cm right lower lobe mass. (B) Axial contrast-enhanced CT shows a smoothly marginated mass containing large amounts of central fat.

2024年8月12日 · Once found, or in the case of asymptomatic hamartoma, multiple diagnostic strategies are available to determine the nature of the lesion. On imaging, eg, chest radiographs or computed tomography (CT) scans, masses present as coin-shaped and solitary, with well-defined edges; they typically measure less than 4 cm in diameter.
Pulmonary hamartoma: CT findings. | Radiology - RSNA …
Forty-seven patients with a proved (n = 31) or presumed (n = 16) diagnosis of pulmonary hamartoma were studied prospectively by thin-section computed tomography (CT). CT criteria for hamartoma included a diameter of 2.5 cm or less, a smooth edge, and focal collections of fat or fat alternating with areas of calcification.
Imaging of Lung Hamartomas by Multidetector Computed …
Hamartomas constitute 8% of solitary lung nodules and 75% of benign nodules. Most are discovered on routine x-ray film and require further evaluation. Computed tomography (CT) is insufficient for a benign versus malignant diagnosis in about 30% of cases.
multidetector CT (MDCT) for the diagnosis of pulmonary ham-artoma has not been previously described in the English litera-ture. Accordingly, the purpose of this study was to describe the dynamic CT findings of pulmonary hamartoma presenting as a SPN as well as to correlate these findings with the histopatho-logic findings.

2024年3月1日 · CT scan revealed the typical findings of chest wall hamartoma, and the MR showed heterogeneous signal intensities of the mass on T1- and T2-weighted images. The MR also revealed more concisely a secondary aneurysmal bone cyst formation with multiple fluid-fluid levels on the T2-weighted image.
