A 27-year-old man presented with intermittent right knee pain for 1 year with no previous trauma. Physical examination revealed only tenderness over the patella. Typical fluid–fluid levels were visible on magnetic resonance imaging (MRI), which highly suggested aneurysmal bone cyst (ABC) of the patella. After removal of a large window of thin cortical bone, curettage and bone grafting followed by cerclage wiring was performed. Histology confirmed the initial diagnosis of primary ABC of the patella. At the final follow-up visit at 71 months after surgery, the patient had normal joint activity with no pain or evidence of recurrence. Previous publications indicated patellectomy in the initial series, but curettage and bone grafting have more recently provided excellent results and good graft incorporation in most cases, even for aggressive lesions. In our patient, thorough curettage and bone grafting through a wide cortical window followed by cerclage wiring fixation and figure-eight sutures was a successful treatment option for primary ABC of the patella without articular disruption.

Access to the cystic lesion of the talar body without damage to the articular surface is difficult. This case report is about a 23-year-old man who had a symptomatic huge cystic lesion in the left-sided talus bone. Radiograph and CT scan showed an expansile lytic lesion within the talar body. The MRI revealed a well-defined lesion with fluid-fluid levels. The needle biopsy aspirate was haemorrhagic, and hence a diagnosis of the aneurysmal bone cyst was made. As the lesion was beneath the talar dome with an intact neck and head, a medial approach with medial malleolar osteotomy was performed. The lesion was curetted out, and the cavity was filled up with a morselised bone graft. The limb was splinted for 6 weeks, and complete weight bearing was started after 3 months. At 1-year follow-up, the lesion was found to be healed up, and the patient was pain-free with no recurrence.

Key findings that aid in the diagnosis of an aneurysmal bone cyst are: 1) typically the patients are young individuals less than 20 years old; 2) an expansile bone lesion is bordered by a thin, low signal intensity rim mass; 3) the lesion is inhomogenously increased in signal on T2-weighted images; and 4) multiple fluid-fluid levels are seen with the mass on T2-weighted magnetic resonance imaging scans.

Abstract Objectives Congenital frontoethmoidal encephaloceles are associated with a shallow sloping forehead. We (1) sought to determine if early repair reverses abnormal forehead slope, and (2) assessed a modification of the fetal profile (FP) line to assess results. Design Study of two cases. Participants Newborns with frontoethmoidal encephaloceles repaired prior to the age of 4 months with cranial base bone grafting. Main Outcome Measures Forehead slope was assessed using a modification of the FP line, defined as the line that passes through the anterior border of the mandible and nasion, on pre and postoperative magnetic resonance imaging (MRI) in the midsagittal plane. A modified FP (mFP) line anterior to the forehead was “ − ”, while a posterior (normal) mFP line was “ + .” The largest distance from the mFP line to the forehead was measured. Results Both infants underwent bifrontal craniotomy, excision of encephalocele, and repair of cribriform plate defect using full-thickness autologous parietal bone before the age of 4 months. Preoperatively, the mFP line was −20.6 mm in case 1, and −9.8 mm in case 2. In both cases, follow-up MRI showed excellent reversal of forehead slope and normal calvarium development. The mFP line improved to +7.4 (age = 16 months) in case 1, and +7.6 (age = 11 months) in case 2. The parietal bone donor site ossified completely within 3 months in both cases. Conclusion Early repair with bone grafting can promote normal frontal bone development and improve forehead slope. The mFP line is a useful method to measure degree of forehead slope.

<p class="abstract">Aneurysmal bone cyst involving the hand are a rare occurrence especially in the proximal phalanx. We report a case of 5 years old female child with proximal phalanx aneurysmal bone cyst treated without bone grafting. Magnetic resonance imaging may show fluid filled spaces but definite diagnosis can only be obtained histologically. It is a benign lesion still it can involve growth plate hence intervention is necessary. The treatment includes curettage with or without bone grafting.</p>

The Subject

ABSTRACT Aneurysmal bone cyst is a cystic lesion that mimics a true neoplasm clinically and radiologically. They are most commonly located in the metaphysis of the long bones, and their occurrence in the calcaneum and transverse process of vertebra has rarely been reported. Aneurysmal bone cyst has various differential diagnoses and histopathology is needed to confirm the diagnosis. Although aggressive, these benign lesions require simple curettage and bone grafting. However, a recurrence rate of up to 59% is reported and needs continuous follow-up. Two cases of aneurysmal bone cyst diagnosed based on X-ray and magnetic resonance imaging in one of the cases and subsequent correlation with histopathology are reported in this communication. The literature on the subject is scanty and hence the report. How to cite this article Tyagi S, Hans P, Kumar H, Mohan V. Radiology of Aneurysmal Bone Cyst at Uncommon Locations: Report of Two Cases.

Fluid Levels

Aneurysmal bone cysts (ABC) are rare, benign, expansile lesions of bone often found in the metaphyses of long bones in pediatric and young adult population. Multiple fluid levels are typically seen on imaging with magnetic resonance imaging (MRI) or computed tomography (CT). We describe a case of a primary ABC in the fibula of a 34-year-old man diagnosed on ultrasound with a mobile fluid level demonstrated sonographically.

Objectives: We analyzed the magnetic resonance imaging (MRI) manifestations of fetal corpus callosum abnormalities and discussed their prognosis based on the results of postnatal follow up. Methods: One hundred fifty-five fetuses were diagnosed with corpus callosum abnormalities by MRI at our hospital from 2004 to 2019. Gesell Development Scales were used to evaluate the prognosis of corpus callosum abnormalities after birth. Results: Corpus callosum abnormalities were diagnosed in 149 fetuses from singleton pregnancies, and 6 pairs of twins, 1 in each pair is a corpus callosum abnormality. Twenty-seven cases (27/155) were lost to follow up, whereas 128 cases (128/155) were followed up. Of these, 101 cases were induced for labor, whereas 27 cases were born naturally. Among the 27 cases of corpus callosum abnormality after birth, 22 cases were from singleton pregnancies (22/27). Moreover, 1 twin from each of 5 pairs of twins (5/27) demonstrated corpus callosum abnormalities. The average Gesell Development Scale score was 87.1 in 19 cases of agenesis of the corpus callosum and 74.9 in 3 cases of hypoplasia of the corpus callosum. Among the 5 affected twins, 2 had severe neurodevelopmental delay, 2 had mild neurodevelopmental delay, and 1 was premature and died. Conclusion: The overall prognosis of agenesis of the corpus callosum is good in singleton pregnancies. Hypoplasia of the corpus callosum is often observed with other abnormalities, and the development quotient of hypoplasia of the corpus callosum is lower compared with agenesis of the corpus callosum. Corpus callosum abnormalities may occur in one twin, in whom the risk may be increased.

Aneurysmal Bone Cysts

PurposeWe have reviewed a series of 150 aneurysmal bone cysts treated over the last 20 years.Patients and MethodsThe lesions were principally located in the tibia, femur, pelvis, humerus, and spine and, in most cases, presented the imaging appearance originally described by Jaffe and Lichtenstein as a blowout with thin cortices.ResultsOnly one of the patients was believed to have an osteoblastoma of the spine with secondary development of an aneurysmal bone cyst, and none of the patients developed additional lesions. The patients were treated primarily with curettage and implantation of allograft chips or polymethylmethacrylate, but some patients were treated with insertion of autografts or allografts. The local recurrence rate was 20%, which is consistent with that reported by other centers.ConclusionAneurysmal bone cysts are enigmatic lesions of unknown cause and presentation and are difficult to distinguish from other lesions. Overall, the treatment is satisfactory, but it is possible that newer approaches, such as improved magnetic resonance imaging studies, may help diagnose the lesions and allow the physicians to plan for more effective treatment protocols.
