Introduction: To report our experience of active surveillance of new bilateral masses after left laparoscopic partial nephrectomy for oncocytoma. Method: A 67-year old man underwent left laparoscopic partial nephrectomy for a renal mass and histology confirmed oncocytoma. At follow-up magnetic resonance imaging (MRI) showed new renal bilateral masses: hence, sonogram-guided percutaneous core renal biopsies were performed confirming the presence of oncocytoma in both kidneys. A re-biopsy was required because of an increasing of the left mass while a histological was also consistent with oncocytoma. Result: At follow of 8 years the patient is well and shows a normal renal function. Conclusion: Oncocytomas show minimal growth rate or progression. MRI has an important role in the appropriate follow-up of renal oncocytomas. Patients with biopsy proven oncocytoma may be managed conservatively by active surveillance (AS).

Objectives: We analyzed the magnetic resonance imaging (MRI) manifestations of fetal corpus callosum abnormalities and discussed their prognosis based on the results of postnatal follow up. Methods: One hundred fifty-five fetuses were diagnosed with corpus callosum abnormalities by MRI at our hospital from 2004 to 2019. Gesell Development Scales were used to evaluate the prognosis of corpus callosum abnormalities after birth. Results: Corpus callosum abnormalities were diagnosed in 149 fetuses from singleton pregnancies, and 6 pairs of twins, 1 in each pair is a corpus callosum abnormality. Twenty-seven cases (27/155) were lost to follow up, whereas 128 cases (128/155) were followed up. Of these, 101 cases were induced for labor, whereas 27 cases were born naturally. Among the 27 cases of corpus callosum abnormality after birth, 22 cases were from singleton pregnancies (22/27). Moreover, 1 twin from each of 5 pairs of twins (5/27) demonstrated corpus callosum abnormalities. The average Gesell Development Scale score was 87.1 in 19 cases of agenesis of the corpus callosum and 74.9 in 3 cases of hypoplasia of the corpus callosum. Among the 5 affected twins, 2 had severe neurodevelopmental delay, 2 had mild neurodevelopmental delay, and 1 was premature and died. Conclusion: The overall prognosis of agenesis of the corpus callosum is good in singleton pregnancies. Hypoplasia of the corpus callosum is often observed with other abnormalities, and the development quotient of hypoplasia of the corpus callosum is lower compared with agenesis of the corpus callosum. Corpus callosum abnormalities may occur in one twin, in whom the risk may be increased.

The increasing use of radiological examination, especially magnetic resonance imaging (MRI), will probably increase the risk of unintended discovery of bone marrow abnormalities in patients where a hematologic disease would not be expected. In this paper we present four patients with different hematologic malignancies of nonplasma cell types. In all patients the MRI bone marrow abnormalities represent an initial presentation of the disease. These case reports illustrate the importance of a careful diagnostic follow-up without delay of patients with MRI bone marrow abnormalities, because such abnormalities can represent the first sign of both acute promyelocytic leukemia as well as other variants of acute leukemia.

Abstract Objective To explore the feasibility of laparoscopic partial nephrectomy(LPN) in the treatment of renal hilar tumors. Methods Clinical data of 290 patients undergoing laparoscopic partial nephrectomy from January 2013 to August 2019 were retrospectively analyzed, including 27 patients with renal hilar tumors and 263 patients with non-hilar renal tumors. Perioperative data and follow-up results were compared between the two groups. Results Tumor size in Group A is smaller(2.97±0.88 vs 3.55±1.46,p<0.05), R.E.N.A.L. nephrometry score of Group A is higher(8.4±1.3 vs 6.5±1.7,p<0.01).The operation time, WIT and intraoperative blood loss in the Group A were slightly higher, but with no statistical difference (p>0.05). There was no significant difference between the two groups in intraoperative ultrasound rate, collection system repair rate, drainage time,postoperative hospital stay, and eGFR changes (p>0.05).The median follow-up period was 40 months. One patient with postoperative pathologic report of angiomyolipoma was found tumor recurrence and was currently undergoing regular reexamination. Conclusion Three-dimensional laparoscopic partial nephrectomy for renal hilar tumors is safe and feasible after detailed preoperative evaluation of the tumor and selection of appropriate surgical strategies.
