[Trans-sphenoidal spread of rhinopharyngeal neoplasms. Correlations between computerized tomography and magnetic resonance].

In 1957 Teoh observed, in an autopsic series of 31 patients with nasopharyngeal carcinoma, 3 cases of neoplastic spread through the marrow spaces of the base of the skull, without macroscopic bone alterations. In order to demonstrate in vivo this kind of neoplastic spread, CT and MR examinations of 35 patients with nasopharyngeal carcinoma were reviewed. In 3/26 cases the invasion of the marrow spaces of the clivus was demonstrated. In these cases CT showed only minimal alterations in spongiosa and cortices of the clivus, associated with intracranial soft-tissue tumoral components. MR imaging demonstrated, with great accuracy, the replacement of bone marrow in the clivus by neoplastic tissue of intermediate signal intensity on T1-weighted images. Tumor tissue was characterized by high signal intensity on T2-weighted images. The authors stress the greater utility of MR imaging in evaluating the permeative involvement of the base of the skull.

[Extra-abdominal spread of pelvic neoplasms. CT evaluation and radiotherapeutic implications].

Meyers and other authors have described the extra-abdominal spread of inflammatory abdominal diseases. Conversely, little attention has been paid to the extra-abdominal spread of pelvic neoplasms. The authors have detected, by means of CT, 17 cases of extra-abdominal neoplastic spread in a series of 203 patients with pelvic neoplasms. Neoplastic spread involved the inguinal region in 1 case, the buttock in 6 cases, and the ischiorectal fossa and/or perineum in 12 cases, with more than one region involved in some patients. In such cases CT showed the extension of tumoral tissue beyond the muscular walls of the pelvis. Recurrent pelvic carcinomas are the most common neoplasms spreading outside the pelvis. Surgical obliteration of the pelvic fasciae can explain such a behavior. Differential diagnosis is to be made with inflammatory pelvic diseases with extrapelvic spread. When a pelvic tumor spreads outside the pelvis it can be seen as a primitive gluteal or inguinal or perineal mass. CT demonstration of such an insidious event is mandatory for both a correct diagnosis and radiation treatment planning.

[Ultrasonic study of the pelvis in patients with Cooley's anemia].

Nowadays the role of sonography (US) as a method of first choice in female pelvic pathology, is well determined. The authors used sonography in 23 patients aged between 13 and 36 years, affected by thalassemia major, in order to determine biometric and structural data of both uterus and ovaries. Morphological and clinical-laboratory studies have been performed in order to have a complete vision about the delay in ovarian maturation, commonly seen in these patients. Many cases of hypoplastic uterus and micropolycystic ovaries have been found. US, simple and widely diffused method, allow the evaluation of uterine and ovarian pathologic conditions and the relationship with ovarian maturation delay, and their follow-up. In some cases US may have a value in previewing menarche, in association with clinical-laboratory data.

[Bronchogenic carcinoma with extramucosal development. Diagnostic problems].

Bronchogenic carcinoma is characterized by three different patterns of spread: endobronchial, the commonest, submucosal, and peribronchial. While the diagnostic yield of bronchoscopy is very high for endobronchial masses, both submucosal and peribronchial tumors are more difficult to detect, and standard forceps biopsy can be negative. In such cases transbronchial needle aspiration biopsy allows higher diagnostic accuracy. CT findings of extramucosal neoplastic spread are not specific. Thickening of the bronchial walls is the commonest sign, but CT is inaccurate in predicting whether bronchial thickening will result in endobronchial/extramucosal neoplasm, fibrosis or bronchial wall edema. Despite this inaccuracy, CT is complementary to bronchoscopy since it allows to: 1) detect a pathology in the bronchial walls, which appear thickened; 2) delineate the extent of extraluminal spread; 3) help plan transbronchial needle aspiration biopsy.

Perineural spread of nasopharyngeal carcinoma: radiological and CT demonstration.

Perineural spread is well known to be the most insidious form of tumour spread of a number of head and neck malignancies. However, perineural extension of nasopharyngeal carcinoma (NC) is a poorly recognized event. Four cases of perineural metastases from NC have been detected with pluridirectional tomography and CT. In 3 cases involvement of the Vidian nerve (nervus canalis pterygoidei) and pterygoid canal was observed. In a fourth patient, invasion of one pterygopalatine fossa and perineural spread along ipsilateral maxillary nerve with enlargement and erosion of the foramen rotundum was demonstrated. Radiological diagnosis of clinically unsuspected perineural tumour spread is important because it markedly influences treatment planning and prognosis of NC.

[X-ray computed tomography in pathology of the greater omentum].

CT examinations were reviewed in 19 patients with proved omental lesions (15 metastases, 1 lymphoma, 1 benign mesothelioma, 1 echinococcosis and 1 tuberculosis). Four distinct but aspecific patterns of omental pathology were identified with CT: omental caking; finely infiltrated fat with a "smudged" appearance; discrete nodules; cystic masses. CT is the most reliable radiographic technique to routinely evaluate omental lesions.

[Opacity of the pterygo-palatine fossa].

The pterygo-palatine fossa can be opacified because the invasion by pathologic tissue. This opacification, due to the loss of normal fatty content, has been found in 19 patients on 40 subjects affected by different maxillofacial pathology. The opacification of the pterygo-palatine fossa is a non specific sign and is generally associated with signs of bony involvement. This sign appears particularly usefull when the bony involvement is very slight and of in certain evaluation.

CT demonstration of pelvic hydatid cysts.

We describe the computed tomographic findings in two cases of bilateral hydronephrosis due to hydatid cyst located in the pouch of Douglas. In both cases this location was secondary to the spontaneous rupture of an hepatic cyst.

CT findings in hepatic involvement by Echinococcus granulosus.

The CT findings in hepatic involvement by Echinococcus granulosus are described. Pathognomonic signs of the hydatid nature of a cystic lesion are visualization of the cystic wall on plain CT, calcification of the cyst wall, daughter cysts, and membrane detachment.
