Computed tomography appearances in the linear sebaceous naevus syndrome.

The appearance of C.T. of the head in 11 cases of the linear sebaceous naevus syndrome are presented. From these it is argued that the pathology represents a disorder of neuronal migration and organisation rather than differentiation. Since three of the cases had evidence of CNS tumour in addition to two in the literature, it would appear that a further aspect of this disorder is a failure of growth constraint. This is paralleled by a similar tendency in the skin lesion which should be considered premalignant. Normal intelligence is rare in this condition and co-exists only with a normal C.T. scan. The early onset of fits is not necessarily associated with subsequent mental handicap.

[Atypical presentation of distant metastases from hepatocarcinoma].

Hepatocarcinoma (HCC) is the most frequent primary malignant hepatic tumour. These tumours usually develop in cirrhotic liver; for this reason, periodic screening using alphafetoprotein determination and abdominal ultrasonography is considered in cirrhotic patients with preserved hepatocellular function. This strategy allows early detection of HCC, increasing the proportion of curable tumours. The most frequent metastasic dissemination is portal vein neoplasic thrombosis, being unusual the occurrence of spread metastases in other organs. We present 3 cases of atypical HCC metastasis with non specific clinical manifestations which initial diagnosis was wrong. Because of a longer survival of these patients in recent years, spread metastasis might be considered in patients with known HCC and non specific symptoms.

Nodular trichoblastoma with adamantinoid features.

We report a cutaneous tumor characterized by follicular differentiation and adamantinoid features that we consider to be part of the histopathologic spectrum of trichoblastoma. Previously, similar lesions have been reported in the medical literature as cutaneous lymphadenoma or lymphoepithelial tumor of the skin.

Tumor invasion of the anterior skull base: a comparison of MR and CT studies.

Seven patients who had tumors arising in the anterior face or paranasal sinuses and invasion of the anterior skull base were evaluated with magnetic resonance (MR) and high resolution CT. Magnetic resonance was superior in evaluating tumor encasement of the carotid artery and invasion of the cavernous sinus; for assessing the relationship of the tumor to the anterior brain, optic nerves, and optic chiasm; in providing coronal images free from dental artifact; and in determining tumor extent within the infratemporal fossa. Bone destruction was more easily observed on CT than MR.

Neurologic implications of glomus tumors in the head and neck.

Seventy-six patients with glomus tumors were evaluated. The incidenc- of cranial nerve paralysis in 37 percent and the incidence of intracranial extension is 14.6 percent. Jugular foramen syndrome is associated with 50 percent, and hypoglossal nerve involvement with 75 percent incidence of posterior fossa extension. Horner's syndrome is associated with 50 percent of middle cranial fossa invasion. The incidence of CNS tumor involvement with cranial nerve paralysis (not including VIIth nerve) is 52 percent.

MRI in Sturge-Weber syndrome.

Five children (3 girls, 2 boys, aged from 1 to 18 years) presenting with Sturge-Weber syndrome were explored by MRI with contrast injection in 2 cases. The respective positions of CT and MRI are discussed: CT is the method of choice to display leptomeningeal calcifications. MRI seems to be more accurate than CT to determine the location of the lesions and to demonstrate the enhancement of the angioma after contrast injection.
