Radionuclide angiocardiography: use in the detection of myocardial rhabdomyoma.

A neonate with a large rhabdomyoma of the heart was evaluated with radionuclide angiocardiography. The images revealed a "cold" area on the inferior surface of the heart which displaced the left ventricle. The findings were correlated with radiographic angiocardiography and were verified at surgery and autopsy. The value of this noninvasive technique in the evaluation of a seriously ill neonate is stressed.

Rhabdomyoma of the head and neck demonstrated by prenatal magnetic resonance imaging.

A case of fetal rhabdomyoma (myxoid type) of the head and neck demonstrated on prenatal magnetic resonance imaging (MRI) is presented. This benign tumor of skeletal muscle is uncommon and should not be confused with its malignant counterpart-rhabdomyosarcoma. With the increasing use of ultrafast MRI, the radiologist is more likely to encounter head and neck masses in the fetus.

Cardiac rhabdomyomas in a newborn baby. Early diagnosis and treatment.

Cardiac tumours are rarities in newborn infants. The majority of them are rhabdomyomas as a manifestation of the basic disease-tuberous sclerosis. The clinical picture may vary from serious arrhythmias to A-V valve obstruction and gross myocardial dysfunction. Therefore these patients are extremely poor candidates for invasive diagnostic procedures and surgical treatment. Our patient had intrauterine cardiac arrhythmias, and a prenatal echocardiogram showed features of A-V septal defect malformation. Therefore the echocardiogram was repeated soon after birth and it revealed intracardiac tumours. The patient was operated on the first day of life and four intracavitary tumours were successfully removed.

Intracardiac rhabdomyomas in neonates: report of three cases.

Three cases of intracardiac rhabdomyomas in neonates are presented. All were diagnosed by ultrasound, one prenatally and two directly after birth. Two of the patients were operated on during the neonatal period. The operations were carried out on the ultrasound findings alone. One patient was considered inoperable and died at three weeks of age. The two surviving patients have no cardiac symptoms and involution of the tumors has taken place. Two of the three patients have shown signs of tuberous sclerosis.

Cardiac rhabdomyomas in tuberous sclerosis.

Echocardiography was performed in 60 people with tuberous sclerosis (TSC) to ascertain the prevalence of cardiac rhabdomyomas at different ages. Twenty-five of 43 children, but only 3 of 17 adults, had tumors, the difference being highly significant. The number and absolute size of the tumors in those who had any were much the same throughout childhood, although the tumors in adults were smaller. Four cases of prenatal tumor recognition are also described; all four later showed signs of TSC, although none had tumors at birth. One of these four is already included in the series of 60, and one single tumor was removed surgically; in the other two the tumors regressed, as they did in the only three infants in the group of 60. The evidence presented herein, together with some published case reports, suggests that echocardiography may afford the most useful diagnostic test for TSC in early infancy and also that a conservative policy should be followed in the management of symptomatic tumors.

Laryngeal rhabdomyoma in a dog.

A 4-year-old spayed female Golden Retriever was presented for investigation of progressive loss of bark, continuous panting and increased upper respiratory noise. Examination of the larynx and pharynx under general anaesthesia identified a spherical 5 x 3 cm mass involving the right arytenoid cartilage. Cytological examination of fine needle aspirates from the mass suggested the tumour was a carcinoma, however histological examination in association with immunoperoxidase and histochemical staining identified the mass as a laryngeal rhabdomyoma.

Immunochemistry and electron microscopy of head and neck rhabdomyoma.

Rhabdomyomas are rare benign tumours originating in skeletal or cardiac muscle. Extracardiac tumours are usually situated in the head and neck. Four cases are presented, three arising in the larynx and the other in the cervical region. All four cases were studied by light and electron microscopy, and in three immunohistochemical staining for myoglobin, desmin, and vimentin was carried out to study the diagnostic features of the lesions and their histogenesis.

Laryngeal rhabdomyoma in a golden retriever.

A three-year-old male golden retriever had had progressive dyspnoea, exercise intolerance, stridor, and a modified bark for five months. A mass 2 cm in diameter was present dorsal to the right side of the larynx. Histological examination revealed cross-striations in some elongated cells, consistent with a diagnosis of rhabdomyoma, a diagnosis which was confirmed by positive immunohistochemical staining for myoglobin and desmin. The mass could not be removed without total laryngectomy and a permanent tracheostomy and the dog was euthanased.

Intra-atrial rhabdomyoma causing chylopericardium and right-sided congestive heart failure in a dog.

A six-year-old Staffordshire bull terrier had a four-week history of progressive lethargy, ascites and exercise intolerance. A mass 3 cm in diameter obliterating the right atrial lumen was detected by echocardiographic examination. There were lactescent pericardial and serosanguineous pleural effusions. Histological and immunochemical examinations showed that the mass was a primary rhabdomyoma.

[Tuberous sclerosis associated with rhabdomyoma in the left ventricular outlet tract].

We report a 2-month old newborn with a family history of adenoma sebaceum, achromic spots and renal lithiasis. Echocardiography-magnetic resonance imaging showed a solitary pediculated rhabdomyoma in the left ventricular outlet tract causing a severe systolic aortic valve obstruction. Surgical excision was carried out through the aortic valve with no valvular lesions. The patient presented multiple seizures 24 hours after surgery with good response to medical therapy. Ten days later, computed tomography showed a spot lesion in the subependimary area in the posterior position of the parietal horn, compatible with a hamartoma associated with tuberous sclerosis.

Multiple cardiac rhabdomyomas detected in utero.

Prenatal fetal echocardiography studies detected large multiple cardiac rhabdomyomas and led to the diagnosis of tuberous sclerosis. Despite episodes of bradyarrhythmias and severe lung compression in utero, the neonate did well and was discharged home on day 20 of life. On day 30 of life, the infant expired at home from cardiac arrest secondary to arrhythmia.

Left ventricular intramyocardial rhabdomyoma suggested by coronary angiography.

Coronary angiography, left ventriculography, and magnetic resonance imaging (MRI) indicated that a 45-year-old male with a left ventricular intramyocardial tumor had adult type rhabdomyoma. The tumor was in the lateral wall of the left ventricle, making catheter biopsy unfeasible. Because the undeveloped tumor does not project into the cavity of his left ventricle, the patient had no symptoms. Angiography and MRI are beneficial in diagnosing intramyocardial tumors which other methods do not confirm.

Rare benign neoplasms of the larynx: rhabdomyoma and lipoma.

Two rare benign tumors of the larynx are presented. The first case is a recurrent multifocal rhabdomyoma, the second a lipoma of the larynx. Both tumors were growing beneath a normal-looking mucosa; deep biopsies were necessary to obtain a histologic diagnosis. Lipomas can be diagnosed by CT or MRI. A review of the literature of these two rare benign tumors is also presented.

Adult rhabdomyoma in fine needle aspirates. A report of two cases.

BACKGROUND: Adult rhabdomyoma (ARh) is a rare, benign tumor arising most frequently in the head and neck region and sometimes mimicking malignant tumors clinically. Correct preoperative evaluation of this tumor is of crucial importance as its treatment is complete excision only and not radical surgery. CASES: Two patients with ARh, one tumor presenting near the submandibular gland and the other in the thyroid area, are reported. The first tumor was correctly diagnosed by fine needle aspiration cytology. The second, clinically suspected to be a colloid goiter, was preoperatively diagnosed as such cytologically as well. After the tumor was excised, reexamination of the cytologic specimen disclosed follicle cells admixed with single cells from ARh; these had been interpreted as colloid fragments at the time of primary evaluation. CONCLUSION: Fine needle aspiration evaluation of ARh may be problematic due to the rarity of the tumor and to the similarity of the tumor cells to normal striated muscle and to other tumors in which cells with abundant granular cytoplasm are characteristic. With an awareness of the cytologic features of this uncommon tumor, cytopathologists can render a correct diagnosis.

Evolution of cardiac rhabdomyoma in tuberous sclerosis complex.

The objective of the study was to define the longitudinal evolution of cardiac rhabdomyomas (CR) in patients with tuberous sclerosis complex (TSC). A cohort of patients with TSC who had undergone videotaped echocardiographic (ECHO) examination during the 10-year interval (1984-1994) were retrospectively studied by reviewing and quantifying the CR appearance and associated cardiac abnormalities in sequentially obtained ECHO examinations. Sixteen patients with TSC (8 males) underwent a total of 35 recorded studies. Ten of the 16 (62.5%) had CR identified at initial study; none were found in the atria. Localization was the ventricular walls as compared with the ventricular septum by a ratio of 2:1. The number of CRs sequentially studied declined as follows; initial study: 23 lesions in 10 patients; second study: 16 lesions in 8 patients; third study: 12 lesions in 5 patients; and fourth study: 4 lesions in 2 patients. Total CR size index declined at each study as follows: initial index of 2,684; second index of 1,746 (-35% from initial); third index 1,141 (-57% from initial); and fourth index 705 (-74% from initial). Complete spontaneous regression of CR was seen by age 6 years with prolonged gradual resolution thereafter. Two patients had bicuspid aortic valves and two had conduction defects. Patients with TSC who have CR can be expected to experience a decline in both the number and size of CR over time; early complete regression on ECHO occurs before age 6 years.
