Yong Sub SONG ; Chang Min PARK
Journal of the Korean Radiological Society 2018;78(5):309-320
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.

Heparin-induced thrombocytopenia (HIT) is a serious complication of heparin therapy. It represents initially as thrombocytopenia and is associated with venous or arterial thrombosis. It has been reported that platelet factor 4/heparin complex antibody plays an important role in the pathogenesis of HIT. Patients on hemodialysis have a high risk of developing HIT because heparin is administrated in hemodialysis as anticoagulant. Thrombocytopenia usually occurs 5 to 10 days after the onset of administration, but occasionally, it may occur rapidly in patients who have preformed antibodies from recent heparin use. We report here 2 cases of HIT with platelet factor 4-heparin reactive antibody in hemodialysis patients.

Cases of spontaneous regression of cerebral aneurysm remnant after incomplete surgical clipping have been rarely reported. This paper reports the regression of an aneurysm remnant after incomplete surgical clipping during postsurgical follow-up. A 50-year-old male presented with subarachnoid hemorrhage because of rupture of an anterior communicating artery aneurysm. An emergency clipping of the aneurysm was performed. A cerebral angiography, which was performed two weeks postoperatively, revealed an aneurysm remnant. The patient refused additional treatment and was discharged without apparent neurological deficit. One-year follow up cerebral angiography demonstrated a partially regressed aneurysm remnant.

A Bednar tumor is a rare pigmented subtype of dermatofibrosarcoma protuberans (DFSP). The clinical and histopathological findings of Bednar tumors are identical to DFSP, except for the presence of melanin-containing cells within the lesion. We present a case of a Bednar tumor on the left anterior chest of a 58-years-old woman. It was presented as an asymptomatic, firm, hyperpigmented 1.8x2.7cm sized nodule with surrounding erythematous patch which had been present for over 35 years. The tumor was treated by wide local excision of the lesion. There has been no evidence of recurrence during a 1 year follow-up period.

PURPOSE: To compare the causes and clinical manifestations of pediatric ocular injuries according to grade level. METHODS: We retrospectively reviewed the medical records of 78 children, 15 years and younger, who had been hospitalized for pediatric ocular injuries, classified them into three groups according to grade level, and compared their clinical manifestations. RESULTS: Eighteen (23.1%) were preschoolers, 39 (50.0%) were elementary school students, and 21 (26.9%) were middle and high school students. The most common causes of injury included toys and household goods at home in the preschool group, toys and sporting activity at home and school in the elementary school group, and sporting activity at school in the middle and high school group. The incidence of ocular injury was higher in the 'without supervision group' (57.7%); however, in the preschool group, it was higher (72.2%) even in the 'supervision group' (P<0.05). In the preschool group, the incidence of perforating ocular injury (P<0.05) and the rate of surgical treatment (P<0.05) were higher than those of other groups. CONCLUSIONS: The causes and clinical manifestations of pediatric ocular injury were different according to school degree. The incidence of pediatric ocular injuries can be decreased more efficiently by recognizing these differences.

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.
