Onyambu, CK.  Submitted.  The pattern of chest radiographic findings in immunocompromised patients at the Kenyatta national hospital. Abstract

The pattern of chest radiograph findings were studied in 280 HIV positive individuals.
These were compared to 40 HIV negative patients who acted as controls. The
commonest disease seen was pneumonia 94 (33.9%), followed by pulmonary
tuberculosis 89 (3l.7%). Mixed infections were seen in 34 (12.2%) cases while PCP
occurred in 16(5.6%) cases. The pneumonia seen was more of bronchopneumonia than
lobar pneumonia in-patients with HIV (33.9) than HIV negative patients (23%).
The cases of pulmonary tuberculosis seen showed less upper lobe distribution than in
HIV negative patients. Most of the cases showed mid and lower zone distribution.
There are less cavitations than HIV negative patients. Also more cases with hilar and
mediastinal nodes were seen. There were 34 (12.2%) cases of mixed infection, which
constituted of 3 (1.1 %) cases of non-Hodgkin's lymphoma. These mainly presented
with hilar and mediastinal nodes. The clinical differentiating features were KS skin
nodules in-patients with pulmonary K.S.

Cerebral venous sinus thrombosis is an uncommon yet potentially life threatening condition which is often under-diagnosed or misdiagnosed because of the variability of the clinical signs and symptoms. The imaging findings are often subtle thus the need for a high index of suspicion. The superior sagittal and transverse sinuses are the most frequently involved. The correct diagnosis of cerebral venous thrombosis relies on neuroimaging studies. The two cases reported highlight the fact that the radiologist may be the first clinician to suspect and diagnose this condition. This ultimately affects prognosis as early diagnosis and treatment reduces morbidity and mortality.
