Pulmonary subsolid nodules (SSNs) refer to the pulmonary pure ground-glass nodules and part-solid nodules. SSNs are frequently encountered in clinical settings, such as in screenings conducted with chest computed tomography. The main concern regarding pulmonary SSNs, particularly when they are persistent, has been a lung adenocarcinoma and the precursors to this condition. This review aims at describing the current understanding of the imaging features, histology, natural course, and to present the current management protocols based on the guidelines recently established by the Fleischner Society.

Primary pulmonary hypertension is a rar, incurable, and progressive clinical entity. When associated with pregnancy, the prognosis of primary pulmonary hypertension is worsened with maternal mortality rates of at least 50%. The patient was a 29-year-old mother in her 2nd pregnancy, with previous uncomplicated gestation, 5 years ago. She had been well until the 28th week of present gestation when she was admitted because of increasing dyspnea on exertion. She was a housewife with no remarkable family and past histories. We have experienced a patient with primary pulmonary hypertension in pregnancy. She was treated with an oral calcium-channel blocker and low-molecular-weight heparin and was delivered vaginally with good maternal and fetal outcome. So we report a case of primary pulmonary hypertension associated with pregnancy and review literature.

PURPOSE: To report brain metastasis of hepatocellular carcinoma presenting as homonymous hemianopia. CASE SUMMARY: A 51-year-old female with a history of hepatectomy and diagnosis of hepatocellular carcinoma (HCC) 19 months earlier was referred to our neuro-ophthalmology clinic for evaluation due to headache and decreased visual acuity over the past several months. Best visual acuity was 20/20, and the results of all other aspects of our examination were normal except Humphrey automatic perimetry, which showed complete left homonymous hemianopia. Brain magnetic resonance imaging showed a large mass in the right occipital lobe. Craniotomy and removal of tumor were performed. HCC was confirmed by histopathologic examination. CONCLUSIONS: Metastasis of hepatocellular carcinoma to the occipital lobe is extremely rare but can present as homonymous hemianopia. Therefore, clinicians should be aware of this when examining a patient with a history of HCC.

The authors analysed radiologic findings of the posterior fossa lesions as well as incisural and supratentorial lesions in 40 patients who were diagnosed by transfemoral serial vertebral angiography at Catholic Medical Center since October 1972 to April 1976. We also attempted to evaluate the diagnostic value in the diagnosis of the lesions according to the site of involvement. The tumors of the fourth ventricle or vermis demonstrated abnormal findings corresponding to the area of involvement, however the lesion could not be defined accurately with the study. Cerebellar hemispheric or tentorial tumors were diagnosed with considerable accuracy by vertebral angiography. Infratentorial vascular lesions were clearly demonstrated with serial vertebral angiography but the accuracy of diagnosis was argumented with subtraction technique. The evidence of compression of the brain stem was demonstrated with considerable accuracy by serial vertebral angiography. Furthermore exact site and direction of the compression could be outlined with the study. For the posterior temporal or occipital tumors which were not able to diagnose definitely with carotid angiography, considerable diagnostic accuracy was carried by the vertebral angiography. Definite diagnosis of the posterior third ventricle tumors or thalamic lesions was able to obtain with serial vertebral angiography.

OBJECTIVE: To measure the orientation of the facet joints of cervical spine (C-spine) segments in the sagittal plane, known as the pedicle-facet (P-F) angle, and to use these measurements to evaluate the relationship between the P-F angle and the amount of vertebral anterolisthesis in patients with degenerative cervical spondylolisthesis (DCS). METHODS: A retrospective case-control study was performed including 30 age- and sex-matched patients with DCS and 30 control participants. Anterior-posterior and lateral view radiographs of the C-spine were obtained in a standing position. The P-F angle at all cervical levels and the amount of anterolisthesis at C4-5 were measured from lateral view plain radiographs. RESULTS: The P-F angles at C4-5 were 141.14+/-7.14degrees for the DCS group and 130.53+/-13.50degrees (p=0.012) for the control group, and at C5-6 were 137.46+/-8.53degrees for the DCS group and 128.53+/-16.01degrees for the control group (p=0.001). The mean P-F angle at C4-5 did not correlate with the amount of anterolisthesis (p=0.483). The amount of anterior slippage did correlate with age (p<0.001). CONCLUSION: The P-F angle was intrinsically higher at C4-5, compared to C5-6, in both the DCS and control groups, which might explain the increased likelihood for anterolisthesis of C4. Higher P-F angles in the DCS group may be a predisposing factor to slippage. The P-F angle may interact with age to increase incidence of anterolisthesis with increasing age.

Myxomas are the most common primary benign cardiac tumor. In general, myxoma has a benign growth and chronic entity, so symtoms of myxoma are vague and mild. Therefore the association of an atrial myxoma with acute pulmonary edema and syncope appears to be very rare. Even though very rare, detection of myxoma is important because it is usually fatal in several cases if unrecognized and untreated. We experienced a case of left atrial (LA) myxoma presenting as acute pulmonary edema and syncope of unknown cause in 47 years old female patient. A mass located on left atrium was excised en bloc, and the patient recovered uneventfully. We report the case along with literature review.
