Successful excision of an atrial fibroma in a four-month-old male infant.

This report presents an infant who was initially admitted with a pericardial effusion. Subsequent evaluation led to the diagnosis of a primary cardiac tumor. Excision of the tumor which arose from the atrial septum was possible only by removing most of the free right atrial wall and a portion of the septal leaflet of the tricuspid valve. Reconstruction of the tricuspid valve leaflet by reattachment of chordae and a partial annuloplasty was done with the right atrial wall being replaced using pericardial tissue. The histology of the tumor was compatible with a fibroma, a type not previously reported in this location in the pediatric age group. Twenty-one months following operation, the child was restudied and the catheterization revealed mild to moderate tricuspid regurgitation and no recurrence of the tumor. The child is now 4 years of age and remains asymptomatic with normal growth and development and no evidence of fibromatosis.

Hemorrhagic infarction of fibroma. MR imaging appearance.

We experienced a case of hemorrhagic infarction of the ovarian fibroma and that indicated the characteristic following appearance: exhibiting a high signal intensity area observed at the periphery of mass on T1-weighted MRI (magnetic resonance imaging). It was thought that this appearance developed because hemorrhagic infarction was caused by subacute ovarian torsion. This is a useful finding for suspecting hemorrhagic infarction preoperatively.

CT and MRI of congenital sinonasal ossifying fibroma.

We report a 9-year-old boy with a sinonasal ossifying fibroma, probably congenital, with atypical findings on CT and MRI. CT revealed a soft-tissue density mass in the sphenoethmoidal sinuses, nasal cavity and right maxillary sinus with a few foci of calcification and with remodelling and destruction of the adjacent facial bones. MRI showed high signal on T2- and intermediate signal on T1-weighted images. A thin, partly enhancing outer shell and some nonenhancing septa were visible on contrast-enhanced images. MRI also showed the tumour to extend into the anterior cranial fossa. Subtotal removal was performed. We compare our findings with reports in the literature and discuss the differences from fibrous dysplasia.

Juxtacortical chondromyxoid fibroma arising in an apophysis.

We present a rare case of juxtacortical chondromyxoid fibroma arising in the lesser trochanter of the right femur which corresponds to an apophysis. Radiography showed a well-defined expansive lesion with a sclerotic margin measuring 5x3.5 cm in diameter in the lesser trochanter. On spin echo T1-weighted images, the lesion revealed low signal intensity similar to muscle. On spin echo T2-weighted images, the lesion revealed high heterogeneous signal intensity, which after gadolinium injection showed heterogeneous enhancement. The inner margin of the cortex was intact and adjacent bone marrow was of normal signal intensity. The outer margin of the lesion was also clearly defined and extension into adjacent soft tissue beyond the exophytic cortical outgrowth was not evident.

Fibroma of tendon sheath of the infrapatellar fat pad.

We report on a 13-year-old boy who was found to have a fibroma of the tendon sheath associated with the patellar tendon and within Hoffa's fat pad of the knee. This benign tumor has never been described in this location previously. The MRI characteristics are correlated with the histologic findings.

Chondromyxoid fibroma of the metacarpal.

This report describes a chondromyxoid fibroma which developed in the distal part of the second metacarpal of a 12-year-old girl. The tumor is rare, perhaps the rarest of all bone tumors, and the occurrence in a metacarpal of a young female is extraordinarily uncommon.

Chondromyxoid fibroma of the foot and ankle: 40 years' Scottish bone tumour registry experience.

Ten cases of histologically proven chondromyxoid fibroma (CMF) of the foot and ankle with a mean follow-up of 6.1 years were retrospectively reviewed using the Scottish Bone Tumour Registry. The patients' mean age was 19 years; there were six males and four females. The anatomical locations were five phalangeal, three metatarsal, one tarsal affecting body of os calcis and one distal tibial. The median delay in presentation was 4.5 months. The modes of presentation were pain only (n=4), painful lump (n=4) and painless lump (n=2). The typical radiological finding was an expansile, lobulated, cystic lesion. Cortical erosion was documented in 80% patients. In four cases, curettage alone was carried out, while five patients underwent curettage along with autogenous bone grafting. One patient with distal phalangeal CMF had a primary toe amputation. Two patients had recurrences 9 and 16 months after their initial curettage. Both of them were males with proximal phalangeal CMF, associated with cortical erosion. Foot and phalangeal CMF initially treated with curettage only should be closely followed up, as we observed a 20% recurrence rate within a 2-year period. Cases featuring cortical erosion require thorough curettage and may require autogenous bone grafting to prevent fracture.

Giant fibroma in the left ventricle of an infant: imaging findings in magnetic resonance imaging, echocardiography and angiography.

The diagnosis of a rare case of giant intraventricular fibroma in an infant by MRI in comparison with other imaging modalities, such as echocardiography and angiography, is discussed. For preoperative planning only MRI showed the myocardial infiltration. The myocardial blood supply of the tumor could be evaluated qualitatively by contrast-enhanced MRI, but the direct visualization of the distally located branches could only be assessed by coronary angiography. Magnetic resonance coronary angiography using the navigator technique failed to depict the distal part of the coronaries. The obstruction of the left ventricle outflow tract could be assessed and quantified by all imaging modalities.

Juvenile ossifying fibroma: CT and MR findings.

We describe the CT findings in four patients and the MR imaging in one patient with juvenile ossifying fibroma. Three lesions involved the maxillary sinus and extended to the surrounding structures; one lesion was confined to the maxillary bone. CT scan revealed well-defined, expansile lesions with variable amount of calcifications. On MRI one lesion had intermediate signal intensity with significant contrast enhancement.

Twisted ovarian fibroma with high signal intensity on T1-weighted MR image: a new sign of torsion of ovarian tumors?

Torsion of ovarian tumors is often difficult to diagnose, because of non-specific clinical, laboratory, and imaging findings. We report a case of twisted ovarian fibroma whose main characteristic was the presence of large areas of high signal intensity on both T1- and T2-weighted MR images due to the passive congestion of the mass. This previously unreported finding should be considered a sign of ovarian torsion and may facilitate prompt surgical intervention.

Desmoplastic fibroma of the skull in an infant.

CASE REPORT: A 1-year-old girl presented with a 10-month history of progressive protuberance of the left frontal skull. Magnetic resonance imaging and computed tomography demonstrated a large osteolytic interosseous mass extending to the frontal sinus and temporal base without any intracranial invasion. A fronto-temporo-parietal craniectomy of the outer skull table and excision of an interosseous tumor resulted in local dural exposure in the temporal area that was covered by cranioplasty. Pathological examination identified desmoplastic fibroma (DF) of the skull. The patient's cranial asymmetry was improved without recurrence of the tumor up to the 12th month after excision. DISCUSSION: In the literature, 11 cases of DF of the skull have been reported, two of which have involved children (one an infant). We report the second known infantile case of DF of the skull.

Juvenile (calcifying) aponeurotic fibroma of the neck.

A case of juvenile (calcifying) aponeurotic fibroma (JAF) arising in the neck of a 5-year-old female is presented. The lesion was misdiagnosed as fibrous hamartoma of infancy (FHI) on a superficial biopsy prior to total excision of the mass. Only one instance of JAF of the neck has previously been reported; the tumor is usually located in the distal extremities and often recurs following excision. FHI occurs most frequently at and about the axilla and shoulder, and does not recur in most instances.

Successful partial excision of an intramural fibroma of the left ventricle.

A report of the only surviving adult to undergo partial excision of an intramural cardiac left ventricular fibroma is presented. Good results were obtained by relieving outflow tract obstruction through partial excision of the tumor from the septum and left ventricle. The need for conservative surgical treatment of patients with this rare, benign tumor is emphasized.

Fanconi syndrome associated with a non-ossifying fibroma of bone.

A 20-year-old man presenting with osteomalacia was found to have the Fanconi syndrome, as evidenced by hypophosphatemia with hyperphosphaturia, glycosuria in the presence of normoglycemia, and generalized aminoaciduria. After removal of a non-ossifying fibroma of the left tibia, the renal tubular abnormalities promptly resolved with subsequent healing of the osteomalacia. A humoral factor released from the tumor may have caused the disorder in proximal renal tubular cell transport.
